  • MacBook Pro battery capacity 65K mAh

    - by Alexander Gladysh
    I have a 15" MacBook Pro 3.1 (that is Late 2007 model AFAIR). I've bought it new a couple of years ago. Recently its on-battery power lifespan became very short (30 to 10 minutes). When my notebook turns itself off due to "low battery" and I press the small button on the battery itself, all LED lights are alight, indicating full charge. When I plug in the power adapter, my Mac displays that "battery is fully charged, finishing charging process" (I have a Russian OS X 10.5.7, so that is a rough translation), but the LEDs on battery itself display (seemingly accurate) status that there are one or two "LEDs still not charged". My battery have as few as 37 recharge cycles (yes, I've neglected calibration over the time I've used it). Battery info programs like iBatt2 report battery capacity of 65 337 mAh (with by-design capacity of 5600 mAh). I get it that something went wrong with battery electronics. I've tried resetting my Mac's PRAM and SMC, it did not changed anything. Now I'm trying to recalibrate the battery, but looks like it does not help as well. Will try to recalibrate it several times in a row. I'd buy a new battery if I knew if it is battery fault, not a notebook's. Any suggestions? Update: After recalibration, my battery status now displays battery capacity of 1500 mAh. But with every recalibration (or simply when I use notebook without power adapter plugged in) this number changes in the range from 200 mAh to 1700 mAh. LEDs on battery now are synchronous with what nodebook thinks on the charge level. Also I've noticed that cycle count changes rather slowly. It is now 39, it was 37 when I've started recalibration, and I went through the process at least ten times... So, the main question is: does it look like that replacing the battery would help me (or does it look like this is notebook's problem)? I guess I should try replacing the battery.

  • How to get the correct battery status?

    - by GUI Junkie
    At this moment, ever since I installed Ubuntu on this machine, the battery status says: not present. Looking at this answer, however, I find that /proc/acpi/battery/BAT1/info (sometimes its /proc/acpi/battery/BAT0/info, use tab complete to help) has the following info: present: yes design capacity: 4400 mAh last full capacity: 4400 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 300 mAh design capacity low: 132 mAh cycle count: 0 capacity granularity 1: 32 mAh capacity granularity 2: 32 mAh model number: BAT1 serial number: 11 battery type: 11 OEM info: 11 In accordance to this answer, I've checked the /proc/acpi/battery/BAT1/state file: present: yes capacity state: ok charging state: charged present rate: unknown remaining capacity: unknown present voltage: 10000 mV The acpi -b command returns: Battery 0: Unknown, 0%, rate information unavailable Any suggestions on getting the battery info updated?

  • Brand new battery is 100% charged but at 0% capacity

    - by Chris Conway
    I just bought a brand new battery to replace one that had seemingly died. I followed the instructions that came with the battery and charged it overnight, then ran my computer on battery until it was in a critical state and charged it overnight again. Now the battery appears to be 100% charged and at the same time at 0% capacity—when it's plugged in it doesn't charge and when it's unplugged the computer immediately goes into low power mode. I've taken the battery out and checked the contacts. I've rebooted the system with and without the battery. Nothing seems to help. I'm not sure if I should blame the battery, the laptop, the charger, or the power management software for this state of affairs. The obvious answer would be the battery but I bought this battery because another year-old battery exhibited similar behavior—I assumed it was dead and a Dell tech came to the same conclusion. I'm loathe to order another new battery without first exploring other explanations. What can I do to diagnose this problem? Here's the /proc info: $ cat /proc/acpi/battery/BAT0/state present: yes capacity state: critical charging state: charged present rate: 1 mA remaining capacity: 0 mAh present voltage: 9754 mV $ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 6600 mAh last full capacity: 6789 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 660 mAh design capacity low: 200 mAh cycle count: 0 capacity granularity 1: 66 mAh capacity granularity 2: 66 mAh model number: DELL WK serial number: 4043 battery type: LION OEM info: SMP

  • Netbook performs hard shutdown without warning on low battery power

    - by Steve Kroon
    My Asus EEE netbook performs a hard shutdown when it reaches low battery power, without giving any warning - i.e. the power just goes off, without any shutdown process. I can't find anything in the syslog, and no error messages are printed before it happens. I've had this problem on previous (K)Ubuntu versions, and hoped updating to Ubuntu Precise would help resolve the issue, but it hasn't. The option in the Power application for "when power is critically low" is currently blank - the only options are a (grayed-out) hibernate and "Power off". I have re-installed indicator-power to no effect. The time remaining reported by acpi is unstable, as is the time remaining reported by gnome-power-statistics. (For example, running acpi twice in succession, I got 2h16min, and then 3h21min remaining. These sorts of jumps in the remaining time are also in the gnome-power-statistics graphs.) It might be possible to write a script to give me advance warning (as per @RanRag's comment below), but I would prefer to isolate why I don't get a critical battery notification from the system before this happens, so that I can take action as appropriate (suspend/shutdown/plug in power) when I get a notification. Some additional information on the battery: kroon@minia:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/PNP0C0A:00/power_supply/BAT0 vendor: ASUS model: 1005P power supply: yes updated: Fri Aug 17 07:31:23 2012 (9 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 33.966 Wh energy-empty: 0 Wh energy-full: 34.9272 Wh energy-full-design: 47.52 Wh energy-rate: 3.7692 W voltage: 12.61 V time to full: 15.3 minutes percentage: 97.248% capacity: 73.5% technology: lithium-ion History (charge): 1345181483 97.248 charging 1345181453 97.155 charging 1345181423 97.062 charging 1345181393 96.970 charging History (rate): 1345181483 3.769 charging 1345181453 3.899 charging 1345181423 4.061 charging 1345181393 4.201 charging kroon@minia:~$ cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charging present rate: 332 mA remaining capacity: 3149 mAh present voltage: 12612 mV kroon@minia:~$ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 4400 mAh last full capacity: 3209 mAh battery technology: rechargeable design voltage: 10800 mV design capacity warning: 10 mAh design capacity low: 5 mAh cycle count: 0 capacity granularity 1: 44 mAh capacity granularity 2: 44 mAh model number: 1005P serial number: battery type: LION OEM info: ASUS

  • Forked-daapd with alternative soundcard

    - by Mah
    I am trying to configure forked-daapd on my computer, and everything goes well except that in configuration file I can not set a new value for the line corresponding to soundcard. This is the default code in the config file: #card = "default" I want to use a soundcard called "DG2", which is the soundcard no.1 and has a first device that ALSA recognizes as no.0. So, I change the line to the following: card = "hw:DG2,0" I restart the daapd service and the next time I play a file through iTune remote, I get a message in my server log file saying that it can not play the file because the device is busy. Any change in the device name will return a different error, saying that the device does not exist. I am pretty sure no other uses this external device, and I don't understand why I get this message. I have tried hwplug as well, with no result.

  • SMART Status Data Interpretation - Disk Utility

    - by Mah
    Last week my external harddisk (Seagate Barracuda 1.5TB in a custom enclosure) showed signs of failure (Disk Utility SMART Pre-failure status - several bad sectors) and I decided to change it. I bought a new HDD (Seagate Barracuda 2TB) and connected it to my Ubuntu box with a SATA to USB cable that could not report SMART status. I copied all the contents of the old HDD to the new HDD (one partition with rsync, the other with parted cp) and then gently replaced the old HDD with the new one inside my aluminum enclosure. For obscure reasons after reconnecting the new HDD through the old enclosure, the Linux box could not detect my partitions. I recovered the partitions with testdisk and restarted the computer. After the restart I checked the SMART status of the new HDD an I get this: Read Error Rate --------------- Normalized 108 Worst 99 Threshold 6 Value 16737944 I got a high value on the Seek Error Rate as well. Wondering why this happens I copied 2 GB directory from one partition to the other and rechecked the SMART status (5 minutes later). This time I got the following: Read Error Rate --------------- Normalized 109 Worst 99 Threshold 6 Value 24792504 As you see there has been an increase in the error rate. I am unable to interpret these numbers. Is my new hard disk already dying? What are the acceptable values in these fields for Seagate hard disks? Then why the assessment is still good? While I could get temperature and airflow temperature data from my old HDD, I can not fetch them for the new one. I noticed that my old hdd had got really hot sometimes. Is it possible that the enclosure is killing the harddisks due to high temperature?... Thanks

  • Macbook pro asks me to "Service Battery"

    - by Uwe Honekamp
    A couple of weeks ago I checked the battery and at that point in time (after 160 load cycles) it still had a capacity of 5000 mAh. Today, my 2006 macbook pro tells me via the battery menu to "Service Battery". According to Coconut Battery the current capacity is only 1590 mAh. The corresponding help text suggests contacting an Apple Authorized Service Provider (AASP) to have the computer checked. Before I decide to throw money at the AASP I'd like to understand what the AASP could possibly do to eliminate the problem. Isn't it more likely that the battery simply broke at 160 cycles and needs to be replaced? Are there any means by software or firmware to influence battery behavior? Of course, the computer hardware might be broken but how could this result in the described effect? And yes, I'm currently trying a calibration cycle but I have some doubts that it will save the day.

  • Cannot get temperatures in Dell Studio 1558

    I could never get proper temperatures on my Dell Studio 1558. lm-sensors and acpi give wrong readings. The output of sensors is, $ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +26.8°C (crit = +100.0°C) temp2: +0.0°C (crit = +100.0°C) acpi -V gives me, $ acpi -V Battery 0: Full, 100% Battery 0: design capacity 414 mAh, last full capacity 369 mAh = 89% Adapter 0: on-line Thermal 0: ok, 0.0 degrees C Thermal 0: trip point 0 switches to mode critical at temperature 100.0 degrees C Thermal 0: trip point 1 switches to mode passive at temperature 95.0 degrees C Thermal 0: trip point 2 switches to mode active at temperature 71.0 degrees C Thermal 0: trip point 3 switches to mode active at temperature 55.0 degrees C Thermal 1: ok, 26.8 degrees C Thermal 1: trip point 0 switches to mode critical at temperature 100.0 degrees C Thermal 1: trip point 1 switches to mode active at temperature 71.0 degrees C Thermal 1: trip point 2 switches to mode active at temperature 55.0 degrees C Cooling 0: LCD 0 of 15 Cooling 1: Processor 0 of 10 Cooling 2: Processor 0 of 10 Cooling 3: Processor 0 of 10 Cooling 4: Processor 0 of 10 Cooling 5: Fan 0 of 1 Cooling 6: Fan 0 of 1 I suspect even hddtemp gives bogus readings as its always at 46 $ sudo hddtemp /dev/sda /dev/sda: ST9500420AS: 46°C I have gone through some bug reports and some used to have the same problem after resuming from suspend. But I always have this problem. I had updated to the latest BIOS from Windows a couple of weeks ago, will updating from Ubuntu change anything? CORRECTION: hddtemp's readings do change. Its now at 45.

  • How to calibrate ASUS k52f battery on Ubuntu?

    - by cutalion
    I'm not sure if the problem is in software or my battery is dying, I'll move my question to another forum if it's not a SO question I have a problem with the battery on my laptop - ASUS K52F. It shows incorrect information about capacity. When I unplug the charger it can work some time, but then it will power off without any warnings. Sometimes it will power off right after I unplug the charger. Here is some info I could get: > uname -a Linux alligator 3.5.0-18-generic #29-Ubuntu SMP Fri Oct 19 10:26:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux > acpi -i Battery 0: Charging, 99%, 18:25:15 until charged Battery 0: design capacity 5235 mAh, last full capacity 69964 mAh = 100% > cat /sys/class/power_supply/BAT0/uevent POWER_SUPPLY_NAME=BAT0 POWER_SUPPLY_STATUS=Charging POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CYCLE_COUNT=0 POWER_SUPPLY_VOLTAGE_MIN_DESIGN=10800000 POWER_SUPPLY_VOLTAGE_NOW=9246000 POWER_SUPPLY_POWER_NOW=176000 POWER_SUPPLY_ENERGY_FULL_DESIGN=**48400000** POWER_SUPPLY_ENERGY_FULL=**646822000** POWER_SUPPLY_ENERGY_NOW=**643588000** POWER_SUPPLY_MODEL_NAME=K52F-44 POWER_SUPPLY_MANUFACTURER=ASUSTek POWER_SUPPLY_SERIAL_NUMBER= I noticed, that POWER_SUPPLY_ENERGY_NOW and POWER_SUPPLY_ENERGY_FULL are greater than POWER_SUPPLY_ENERGY_FULL_DESIGN.

  • Dell Studio 1737 Overheating

    - by Sean
    I am using a Dell Studio 1737 laptop. I have been running Linux and have ran Windows recently for a very long time. I upgraded to the 10.10 distribution and since that distro, it seems that for some reason all Linuxes want to push my laptop to extremes. I have recently upgraded to Ubuntu 12.04 since I heart that it contains kernel fixes for overheating issues. 12.04 will actually eventually cool the system, but that is after the fans run to the point it sounds like a jet aircraft taking off and the laptop makes my hands sweat. In trying to combat the heat problems I have done the following: I installed the propriatery driver for my ATI Mobility HD 3600. I have tried both the one in the Additional Drivers and also tried ATI's latest greatest version. If I don't install this my laptop will overheat and shut off in minutes. Both seem to perform similarly, but the heat problem remains. I have tried limiting the CPU by installing the CPUFreq Indicator. This does help keep the machine from shutting off, but the heat is still uncomfortable to be around the machine. I usually run in power saver mode or run the cpu at 1.6 GHZ just to error on safety. I ran sensors-detect and here are the results: sean@sean-Studio-1737:~$ sudo sensors-detect # sensors-detect revision 5984 (2011-07-10 21:22:53 +0200) # System: Dell Inc.

  • Oracle Linux / Symantec Partnership

    - by Ted Davis
    Fred Astaire and Ginger Rogers sang the now famous lyrics:  “You like to-may-toes and I like to-mah-toes”. In the tech world, is it Semantic or is it Symantec? Ah, well, we know it’s the latter. Actually, who doesn’t know or hasn’t heard of Symantec in the tech world? Symantec is thoroughly engrained in Enterprise customer infrastructure from their Storage Foundation Suite to their Anti-Virus products. It would be hard to find anyone who doesn’t use their software. Likewise, Oracle Linux is thoroughly engrained in Enterprise infrastructure – so our paths cross quite a bit. This is why the Oracle Linux  engineering team works with Symantec to make sure their applications and agents are supported on Oracle Linux. We also want to make sure the Oracle Linux / Symantec customer experience is trouble free so customer work continues at the same blistering pace. Here are a few Symantec applications that are supported on Oracle Linux: Storage Foundation Netbackup Enterprise Server Symantec Antivirus For Linux Veritas Cluster Server Backup Exec Agent for Linux So, while Fred and Ginger may disagree on how to spell tomato, for our software customers, the Oracle / Symantec partnership works together so our joint customers experience and hear the sweet song of success.

  • Laptop drains of quickly with battery

    - by Shyam
    I am a user since years in ubuntu and I have not come across this problem with ubuntu till date. My battery drains off immediately after I unplug my AC power. The options I tried: 1) checked the battery state with : cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 392 mAh present voltage: 12476 mV Initially it was showing charging state: charging after 5mins it started displaying as charged. ! Based on that if I remove my AC Power it shows low battery notification. 2) When I run acpi : acpi -b Battery 0: Unknown, 9% The battery state shows as unknown. But initially when we plug-in to AC adapter acpi -b Battery 0: Charging, 9%, 13:04:00 until charged 3) When the check the same with : upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:02/PNP0C09:00/PNP0C0A:00/power_supply/BAT0 vendor: HP power supply: yes updated: Thu Nov 1 16:06:40 2012 (20 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 4.2336 Wh energy-empty: 0 Wh energy-full: 33.1128 Wh energy-full-design: 33.1128 Wh energy-rate: 5.6052 W voltage: 12.474 V time to full: 5.2 hours percentage: 12.7854% capacity: 100% technology: lithium-ion Is the power stats output, It says 5hrs to charge completely, If I charge it even more than 5hrs and unplug the AC power, It again cribs stating LOW BATTERY !! The same thing does not happen with Windows7. Any suggestions/ help will be greatly appreciated.

  • How to rebuild a Li Ion laptop battery?

    - by spoulson
    I have an aging Gateway NX560XL laptop. The battery is toast and a new one, even aftermarket, starts at $130. So, to experiment, I began tearing apart the old battery to see what can be done. I found it used 8 standard size 18650 Li Ion cells arranged two cells parallel then in series (like: ====). Some online shopping revealed ~$7-13/ea replacements depending on mAh output. My plan is to load test to determine the bad cells and replace only those, as I read that typically only 1 or 2 may be bad. I'm proficient with soldering, however these cells are attached with welded tabs. Some of them broke during disassembly and I'm not sure how to reattach them. What I found online are cells like these that have solder tabs pre-welded to the ends so I can solder wires onto. Is there any guide available that provides the instructions and parts to do this kind of rebuild?

  • MacBook says to replace battery. Should I?

    - by Palantir
    Hi! My MacBook says that battery is not charging, and the battery is completely empty (in fact, pressing the button on the battery illuminates no LEDs). If I plug the power adapter off the mac shuts off immediately. I tried with a spare adapter, and it won't charge it. System information says it has 380 cycles. The battery is 2.5 years old. System profiler says the battery has 0 mAh of capacity, and that it should be replaced. Should I just buy a new battery, or should I bring it to an apple point, and leave it there? They can take a look at it (it's on AppleCare), they told me that they will repair it is there is anything wrong with the charging circuit, but they won't give me a new battery. They will keep the laptop for 10 working days at least... I hate when this happens :P

  • Should I use UPS with my laptop to extend the battery life?

    - by Mehper C. Palavuzlar
    I recently bought a new Vaio laptop which has a 4400 mAh battery. I will use it at home most of the time, and I have an unused uninterruptible power supply (UPS). Should I remove the battery and connect my laptop to UPS? If I do that, how much does it effect the battery's life? I know that batteries stand longer when kept in half-charged in a cool place, but their lifespan decreases in time due to age effect as well. So is it worth to keep the battery out of my laptop, use a UPS instead and mount it when necessary? or should I continue to work with battery mounted?

    I have been using Ubuntu 11.04 on DELL Inspiron 14R (N5010) laptop for last three months. Before I switch to ubuntu my laptop battery used to give 2.5 hrs to 3 hrs back-up. But since I have been using ubuntu, it has been reduced to 1hr to 1.5 hrs at max. I tried following commands: $ cat /proc/acpi/battery/BAT0/state which gave result as present: yes capacity state: ok charging state: charged present rate: 1 mA remaining capacity: 4400 mAh present voltage: 12407 mV then I tried $ acpi -b the result was.. Battery 0: Unknown, 100% when I gave command as $ upower -i /org/freedesktop/UPower/devices/battery_BAT0 the result was.. native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 model: DELL W7H3N08 serial: 7114 power supply: yes updated: Sat Nov 24 11:25:34 2012 (21 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: fully-charged energy: 48.4748 Wh energy-empty: 0 Wh energy-full: 48.4748 Wh energy-full-design: 48.9595 Wh energy-rate: 0.011017 W voltage: 12.408 V percentage: 100% **capacity: 52.9253%** technology: lithium-ion Someone please let me know, what is going wrong with my laptop?

Obviously I did something wrong, but what? Here's the script. /*Dom controllers*/ $dom = new DOMDocument(); $dom->loadHTML('index.html'); $id = $dom->getElementById('contact_us'); $p = $dom->appendChild(new DOMElement('p')); $op = $dom->getElementsByTagName('p'); /* Dem POST vars used by dat Ajax mah ziggen, yeah boi*/ if (isset($_POST['Home']) && isset($_POST['About']) && isset($_POST['Contact']) && isset($_POST['sexyText'])){ $home = $_POST['Home']; $about = $_POST['About']; $contact = $_POST['Contact']; $text = $_POST['sexyText']; trim($home); trim($about); trim($contact); trim($text); } function post(){ global $dom, $id, $home, $about, $contact, $text, $textp, $p, $op; $textp = $dom->createTextNode($text); $p->appendChild($textp); $id->replaceChild($p, $op); $dom->saveHTMLFile('index.html'); } post(); echo 1; ?> The error happens at the replaceChild function.

  • Problem with develop of XML Schema based on an existent XML

    - by farhad
    Hello! I have a problem with the validation of this piece of XML: <?xml version="1.0" encoding="UTF-8"?> <i-ching xmlns="http://www.oracolo.it/i-ching"> <predizione> <esagramma nome="Pace"> <trigramma> <yang/><yang/><yang/> </trigramma> <trigramma> <yin/><yin/><yin/> </trigramma> </esagramma> <significato>Questa combinazione preannuncia <enfasi>boh</enfasi>, e forse anche <enfasi>mah, chissa</enfasi>.</significato> </predizione> <predizione> <esagramma nome="Ritorno"> <trigramma> <yang/><yin/> <yin/> </trigramma> <trigramma> <yin/><yin/><yin/> </trigramma> </esagramma> <significato>Si prevede con certezza <enfasi>qualcosa</enfasi>, <enfasi>ma anche <enfasi>no</enfasi></enfasi>.</significato> </predizione> </i-ching> This XML Schema was developed with Russian Dolls technique: <?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.oracolo.it/i-ching" targetNamespace="http://www.oracolo.it/i-ching" > <xsd:element name="i-ching"> <xsd:complexType> <xsd:sequence> <xsd:element name="predizione" minOccurs="0" maxOccurs="64"> <xsd:complexType> <xsd:sequence> <xsd:element name="esagramma"> <xsd:complexType> <!-- vi sono 2 trigrammi --> <xsd:sequence> <xsd:element name="trigramma" minOccurs="2" maxOccurs="2"> <xsd:complexType> <xsd:sequence minOccurs="3" maxOccurs="3"> <xsd:choice> <xsd:element name="yang"/> <xsd:element name="yin"/> </xsd:choice> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:sequence> <xsd:attribute name="nome" type="xsd:string"/> </xsd:complexType> </xsd:element> <!-- significato: context model misto --> <xsd:element name="significato"> <xsd:complexType mixed="true"> <xsd:sequence> <xsd:element name="enfasi" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema> For exercise I have to develop an XML Schema to validate the previous XML. The problem is that oxygen says me this: cvc-complex-type.2.4.a: Invalid content was found starting with element 'predizione'. One of '{predizione}' is expected. Start location: 3:6 End location: 3:16 URL: http://www.w3.org/TR/xmlschema-1/#cvc-complex-type why? is it something wrong with my xml schema? thank you very much
