• Melting plastic around DC-in jack in laptop

  - by Ove

  I recently noticed that the plastic around the DC-in jack of my laptop was warped (melted) a little bit. Since I noticed, I have done some experiments, and saw that the metal tip of the charger heats up very much when I am gaming, or performing CPU-intensive work (it's so hot that i can't hold it between my fingers). When I am using Windows normally (web browsing, music, video), the tip is not hot. I tried using another charger from a compatible laptop, but its metal tip overheated as well, so the problem is not caused by the charger. I have been using this laptop for gaming for 1.5 years and I never had this problem. When gaming I always use a laptop cooler. Dust is not the problem (i cleaned out the dust), and the CPU and GPU temperatures are not higher than when I got the laptop. The only thing that is excessively hot is the charger tip. Because I bought my laptop from the USA, sending it to warranty and back would cost more than the laptop's value, so I need to fix it myself. I have googled around, and I saw that the problem might be the DC-in jack that is located on the motherboard of the laptop. I plan to take the laptop apart and see if it has become loose, and soldering it in place if it has. My questions for you are: Did anyone deal with this problem in the past? Did anyone manage to fix it? Is the DC-in jack the culprit in this case? Or is it possible for the problem to be caused by another part on the motherboard? Is there any way I can check the DC-in jack with a multimeter? What should I measure (resistance, etc)? EDIT: My laptop is a Sager NP5135 (aka Clevo B5130M). I also posted on NBR, including some pictures: link

• Laptop shuts down randomly without warning

  - by Robert P.

  My Asus Zenbook UX32V turns off randomly when I'm working on it. This happens both when the computer is recently turned on (5 minutes), and after being on for several days. I'm not running any heavy software The laptop is not heating The fan is not working on the maximum capacity (it's not heating) It happens when the laptop is lying still on the table It is no warning, it simply goes black It happens both when charging and on battery My guess is that it suddenly lose power somehow. What puzzles me is that I can flip the laptop upside down, sideways, shake it, etc. without it shutting off. This makes me think it's not something that's loose causing occasional short-circuits. I realize that the laptop probably doesn't like flipping and shaking, but it was the best way I could troubleshoot. I rarely turn the computer off, only have it in hibernate or sleep mode (most often hibernate). I've never experienced that the laptop is off when I wake it up from sleep mode. I've had the problem for a few months and it happens 2-8 times a week. Specs: Asus Zenbook UX32V Windows 8.1 (it happened in Windows 8.0 too) Intel i5-3317U CPU @ 1.70GHz The laptop is approx 1.5 years, but it has a small dent on one of the sides that probably voids the warranty. The dent has been there since week one and I don't think it's related to the problems I'm having now. Does anyone have a clue what might cause this, and how it might be fixed? I've read all other questions (some of which are listed below) that seem related to my issue, but none report the same behavior as I'm experiencing. Most report heavy games, heating etc. Asus N53J Laptop randomly shuts down Laptop is randomly shutting off Computer shuts down without warning My laptop acer aspire 5720 suddenly turn off randomly Computer randomly shutting down Windows 8.1 randomly shuts self down ASUS K55VM Laptop unexpectedly shuts down

• I dropped my hp laptop and it has been on the startup repair screen for hours now--what can I do?

  - by tiy

  I dropped my hp laptop (I have windows 7). There was a blue screen with the cursor. It took about an hour or two for the startup repair screen to appear. Then it says to wait at least an hour. I've been charging my laptop for around a day now and the same screen, with a bar with blue moving, is still there. It says it's fixing disc errors. What can I do to get to the windows screen with usernames and pictures/fix it? thanks.

• Laptop battery life drastically decreased compared to Windows 7

  - by Aron Rotteveel

  I am running Ubuntu 10.10 on my Dell Studio XPS 1640 and have about one hour of battery life in it, compared to about 2.5 hours running on Windows 7. This is with wireless and bluetooth on, but still, the difference seems incredible. What could be causing such a difference and is there a way to close the gap without losing core functionality? EDIT: here's some output from powertop. This is with bluetooth turned off and Wifi turned on. The output seems pretty normal to me, but as indicated, this is about 1 hour of battery life on a full battery... Wakeups-from-idle per second : 476.2 interval: 10.0s Power usage (ACPI estimate): 2.5W (1.2 hours) Top causes for wakeups: 30.0% (167.2)D chrome 21.0% (117.3) [extra timer interrupt] 13.9% ( 77.4) [kernel scheduler] Load balancing tick 3.4% ( 18.9)D xchat 7.1% ( 39.8) [iwlagn] <interrupt> 5.9% ( 32.9) AptanaStudio3 3.9% ( 21.6)D java 2.7% ( 14.9) [TLB shootdowns] <kernel IPI> 2.5% ( 14.1) docky 1.8% ( 10.0) nautilus 1.6% ( 9.0) thunderbird-bin 1.0% ( 5.5) [ahci] <interrupt> 0.9% ( 5.0) syndaemon 0.8% ( 4.3) [kernel core] hrtimer_start (tick_sched_timer) EDIT: after changing /proc/sys/vm/laptop_mode to 5 (it was set to 0), wakeups seem to have decreased, although usage still seems far too high: Wakeups-from-idle per second : 263.8 interval: 10.0s Power usage (ACPI estimate): 2.6W (0.9 hours) EDIT: I seem to have discovered the main cause: I was using the open source ATI Drivers. I recently installed the official ATI drivers and laptop battery life seems to have doubled since. EDIT: last edit. The previous 'solution' of installing the official ATI drivers turns out to be a non-solution. Although it does increase battery life, my laptop resolution is maxed out at 1200x800 after a reboot. (Please note that this problem does not need answering in this question as it is a seperate case)

• Wake laptop when lid is opened?

  - by crackout12

  I have a SAMSUNG laptop, which by the experience in the last months, has been a great one. I am actually implementing some functionality to it, and since I noticed, I am able to wake up my laptop from sleep by just opening the lid on Windows 7, however, I need to press to power button to wake up in Ubuntu. Using a program called i-nex, I noted that the kernel DOES dettect a "lid switch", and I am looking forward to use it to wake up function. Any ideas? UPDATE: Thanks @yossile for bringing up some clues! However, output of command cat /proc/acpi/wakeup does not show the LID device. I still tried the second set of commands you gave me with no effect. Then I tried experimenting, guessing that LID should be named by other value, so I tried enabling the others. No victory so far. But I noticed that devices that did not have any pci listings were disabled at all time no matter what I tried. Here is the output of command cat /proc/acpi/wakeup: root@samsung:~# cat /proc/acpi/wakeup Device S-state Status Sysfs node PCE4 S4 *disabled pci:0000:00:04.0 SBAZ S4 *disabled pci:0000:00:14.2 P0PC S4 *disabled pci:0000:00:14.4 GEC S4 *disabled PE20 S4 *disabled pci:0000:00:15.0 PE21 S4 *disabled PE22 S4 *disabled pci:0000:00:15.2 PE23 S4 *disabled PWRB S5 *enabled So maybe it could be that LID is either GEC,PE21, or PE23? Still, there is /proc/acpi/button/lid/LID/state file which shows that LID is opened. Any more ideas?

• Do higher resolution laptop displays matter for programmers?

  - by Jason Baker

  I'm buying a new laptop that I'll be using mainly for programming. A couple of options that really intrigue me are the Asus Zenbook UX31A and the new Retina Macbook Pro. It's obvious that the high-resolution displays on these laptops is useful for entertainment, photo-editing, and other things. My question is this: Do these displays provide any benefit for programmers? Do these displays make code any easier to read? Are they any easier on the eyes after a whole day of staring at the screen?

• Closing lid freezes laptop

  - by trampster

  Closing the lid on my dell studio 15 which is running ubuntu 10.04 freezes the screen. This is a new problem in ubuntu 10.04 which did not exist in 9.10 I have tried playing with all the settings in System-Preferences-Screensaver but nothing seems to make any difference. (please note the Power Management settings are accessible from here so I have tried those too.) I don't need hibernate or suspend. I just want to be able to close the lid, and then open it and still have a working laptop. Is their a settings somewhere that will make Ubuntu ignore the lid closing?

• Screen Brightness Stuck on high on an HP dv7t laptop

  - by theJollySin

  I have an otherwise fully-functioning install of Ubuntu 12.04 on my HPdv7t laptop. When I press the 'brightness buttons' on the keyboard the associated images appear on my screen to say I am increasing/decreasing the screen brightness. When I go into "System Settings" I can move the 'brightness slider bar' up and down. But none of that changes the fact that my screen is stuck on the highest brightness setting. ANY clues on how to fix this would be greatly appreciated. This giant 17-inch monitor is blinding, and this is making it hard to code for any length of time.

• What Is The Proper Laptop Battery Care While Running Laptop Solely On Battery?

  - by Boris_yo

  Because of convenience, I had to move my laptop to another room away from room where I always ran laptop on UPS without using battery. Since so far I always run laptop on battery, I question the proper usage to prolong battery life. Currently I run laptop on battery with power supply so battery is constantly being charged until it is full 100% and when it is, I disconnect power supply and continue working until battery meter shows 10% remaining. That's when I plug in power supply and let it charge until 100% once again while I work. But it takes a lot of time to fully charge laptop while working since my power supply is 60W which should be the reason of such slow charge and I think the kind of charger that I use is express charger. The thought of charging laptop until full, all while doing my work makes me think that if it takes way more time to charge, it might keep battery running warm for the period of charging time which brings me to question about whether I should keep running laptop as I've described above or it would be better to leave power supply constantly connected to laptop to keep battery between 99%-100%? On one hand it won't keep battery warm but it will try to frequently supply charge to battery once it gets 99% to replenish charge to 100% (which might reduce battery life?). On the other hand if I'll keep working solely on battery and recharge it when below 10%, the battery will get warm but only when charged. Can anybody suggest the correct way of running laptop on battery to ensure better battery life? Dell Latitude E6420 Windows 7 64-bit

• Is my laptop good enough to support my development needs? [closed]

  - by KodeSeeker

  I have an ASUS Pentium-R Dual Core CPU running at 2.20Ghz. It has 4 gb of built in ram, currently running a 64 bit Windows 7 . I just started graduate school and Im wondering whether I should go in for a new laptop or just repair the nagging battery on my current one. My requirements include - -Ability to support IDE's - I may end up running Eclipse, Visual Studio's and the like to help with my work. - Ability to run multiple VM's (not concurrently). Im currently running a Ubuntu 12 and 9 as VM's (not sure if this is overloading the system) - I'm a non gamer so I really dont care about a minor glitch caused by running a uber heavy game. -In addition I will have heavy use of Office Application Software and will be using my computer to watch movies and stream media. Looking forward to your replies and suggestions!

• How to Install Mac OS X Lion on Your HP ProBook (or Compatible Laptop)

  - by Usman

  There’s nothing more satisfying than building a hackintosh, i.e. installing Mac OS X on a non-Apple machine. Although it isn’t as easy as it sounds, but the end result is worth the effort. Building a PC with specific components and installing Mac OS X on it can save you thousands of dollars you might spend on a real Mac. And now, it’s time to step into the portable world. Today we will show how you can turn an HP ProBook (or any compatible Sandy Bridge laptop) into a 95% MacBook Pro! Why should (or shouldn’t) you do it? Let’s clarify whether or not it should be done. Firstly, we all know Apple makes awesome laptops. The design, build quality, and the aesthetics (not to mention, the glowing Apple) would make you crave for one. Secondly, all these Apple laptops are bundled with Mac OS X, which (for some people) is the most user-friendly and annoyance-free operating system. Digital artists, musicians, video editors, they all prefer Mac for a reason. So the verdict is, if hardware design is what you really look for, you should get a real Mac, and we are not at all stopping you from doing so. But if you’re only concerned with the OS (and saving a few bucks in your pocket), you may consider giving this a shot. But remember, it may not perform as good as a real Mac does. The results vary, so hope for the best, and proceed with caution. Why HP ProBook?

  Hi Linux Community, After been temporary impressed with the newb Windows 7 and after intensly using it I find my self struggling with the ever slow and buggy windows OS once again. It's Time to go with the Ubuntu/Linux way for a better and faster tomorrow. Unfortunately in my country most Users/Business use Windows based Systems.

• Problems with Intel Video Resolution on Acer Laptop Wide Display

  - by ricstr

  I have an ACER Aspire 5332 laptop which I have just installed Ubuntu 12.04 x64, which is causing some issues with the video display on boot and video resolution. First and foremost, it will only boot past the purple screen if GRUB has been edited to replace 'quick splash' with 'nomodeset'. Secondly, once it has booted with the the 'nomodeset' option, it does not allow me to change the resolution higher or lower from 1024 x 786. Is it OK to use the 'nomodeset' for normal use? Will this compromise performance of other devices? The video card is an on-board one, integrated within the Intel GL40 chip-set. The display is a wide-screen LCD, and under Windows could operate under various resolutions. Ideally I would like it to operate on a resolution to fit the wide-screen display as it a bit stretched out at the moment, and less desktop space as I am used to. I believe the optimal resolution is 1366 x 768. Below is some information from the terminal which may be useful. ricstr@Aspire-5332:~$ lspci | grep -i VGA 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) ricstr@Aspire-5332:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 0.0*

• Can you help diagnose why this laptop running ubantu has crashed and seemingly died

  - by krhodes

  Love any suggestions you have to this problem. My laptop had Window Vista on previously (sorry). Something went wrong, I can't remember, and I tried to reinstall but couldn't, installed a replacement second hand HD, and installed Ubantu instead. It worked ok for a little while, before crashing. I ended up reloading Ubantu three times. It works for a while after (say 3-5 hrs of domestic web browsing), and then crashes. When I turn it on now, it comes up with some options to restart in safe mode, run tests and so on. I can't get it to start normally. I'm not going to re-install again. Below are screen shots of what happens when I follow some of these test options. These screen shots mean nothing to me. Any ideas? Surely I can fix this.... http://i1219.photobucket.com/albums/dd434/keithrhodes1/P1050109.jpg http://i1219.photobucket.com/albums/dd434/keithrhodes1/P1050105.jpg Thanks in advance for any suggestions Keith

• Which powerful laptop, with UK keyboard and 8gb ram

  - by RobinL

  I've been searching high and low for high spec laptops compatible with Ubuntu. The lack of coherent information on the topic is high (considering the number of people who apparently want a good laptop with an OS operating system). So I thought you may have some advice. My requirements: a) has = 8Gb ram b) is compatible with Ubuntu c) has a UK keyboard and charger d) does not cost the Earth Which would you go for? Does anyone have good experience with high-end laptops running Ubuntu? So here's some background research: Samsung Series 7 looks great, but has various problems on Ubuntu, including: poor battery life, touchpad does not work, graphics card not fully supported and sucks power when it does (see [here] and [here], for example). Other options on the [wish list] include: the sensible [Acer] (possibly n.1 choice, but not sure about graphics card compatibility or battery), a nice looking [HP Pavilion dv6-6c56ea], which also has incompatibility issues (see [here] and [here] and check ubuntuforums) And another [Acer] which may be best due to its simplicity and cheapness. Other sub-questions: didn't Dell offer Ubuntu support for decent laptops (above 6Gb ram their offerings are scarce); what about pre-installed options such as those provided by System76? If it weren't for the UK keyboard and charger, I'd probably go for this [amazing-looking] [machine]. Many thanks for any advice, P.s. Apologies for lack of hyperlinks; I'm a noob so only allowed 2 :( All 10 links are available here though for the interested reader :) Robin

• Anything such as a usb laptop charger?

  - by iNinja

  I am looking for a laptop charger that requires no power outlet but instead utilizes a usb port of another computer to charge my laptop. That is, I am seeking a usb-to-laptop port charger, NOT power outlet-to-laptop's usb charger. Is such a product even possible? I am guessing no since the usb port would not be able to supply enough electricity to power the laptop, even to maintain the battery (not charge it).

• Share laptop Wi-Fi with router set up as access point via ethernet cables

  - by obie

  I have an ADSL modem which serves as a wireless router. There's a laptop connected to it through cable. On the other room I have a laptop which is connected through the router wirelessly. Since I have other appliances that need to get connected but are not Wi-Fi capable I have another Wi-Fi router. How can I share the second laptop's Wi-Fi with the second router so that the router can then serve as an access point to give internet to my other appliances through ethernet cables? I want something like this: INTERNETMODEM (WIFI)LAPTOP 1 (WIFI)LAPTOP 2 (WIFI)Router 2 (ETHERNET)DREAMBOX & WDTV What I've tried so far is opened the admin interface of router 2 then set static IP 192.168.100.13 and disabled the DHCP. The DHCP of the main router starts with 192.168.100.1 then I hooked up router 2 with the laptop 2 through Cat5 cable but for some reason it's not working.

• Two virtual computers using one laptop?

  - by JP19

  Hi, I have a laptop and an external display. I am able to use the external display either as extended desktop OR duplicate desktop. I also use a separate keyboard and mouse. So effectively, the laptop acts just as a box without display. I want to know is it possible to use the laptop as 2 virtual PCs. (with separate control). I.E., one person uses the laptop as a laptop, and other person can simultaneously connect a keyboard and mouse and the external display and effectively get a second PC. OS I am using - windows (thought solution for other OSes are welcome). Laptop is a Dell Precision M6300. thanks JP

• 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.
