  • Is my laptop battery dead?

    - by Josh
    Recently my laptop battery will get extremely hot (definitely hotter than it should get) when I charge it. After that I usually end up removing it once it's fully charged to let it cool down, which takes a couple hours... Question is, is my battery dead? My last battery I had that died just ended up lasting 2 - 3 minutes on battery, no weird heat issues. And is there any way to possibly fix this? Probably not but I won't be able to get a replacement anytime soon. UPDATE: A few days ago when this happened and it cooled down, assuming it was fully charged, I ran my laptop on battery, and the battery life lasted about 10 minutes and then the laptop shutdown. I then plugged it in later and charged it back up, and for a while I had a orange light blinking on my laptop - which I assumed meant the battery was dead, especially since I got 10 minutes battery life. Then today, I turned my laptop on and was surprised to see that the battery was at 20% and charging (it's been plugged in since the incident above, so it should have been fully charged when I shut it off) I let it charge up, and as usual it got pretty hot around the time it was fully charged. So I turned my laptop off and pulled the battery out to let it cool down Now the thing is, just now I tried running it on battery, and it's been going for an hour now... so maybe its not dead? (also the orange light is no longer blinking...) Thanks in advance if anyone knows whats going on, and how to fix it, if its fixable =] EDIT: Some info if it helps... my laptop is about 2 years ago, and it's an Asus K50ID. I know laptop batteries usually don't last more than a year but I'm trying to keep this one going for as long as I can.

  • What precautions should I take once defective RAM has been replaced?

    - by DustByte
    I recently discovered that my RAM is faulty (MemTest86+). I am waiting for new RAM to be sent to me.  It was through sheer luck that I discovered something was wrong. I was copying a large amount of big files and decided to verify the copies by their checksums. I discovered strange discrepancies, and noticed that checksum computation for the same file was not consistent. Now, this is the only problem I have encountered; no BSOD, no crashes, no errors. In a sense this makes me more worried than if I would have had massive crashes. I have no idea for how long the RAM has been faulty, and I have no idea if corrupt bits have been saved into files on my hard drives. I do know the RAM was fine two months ago (tested it back then). I am a user of Adobe's Lightroom and I am worried that photos or the catalog itself could carry corrupt data. Question: what should I do once new healthy RAM has been installed? Reinstall Windows (I'm using Windows 7, 64 bit)? Is there a risk that I will be presented with nasty surprises in the future if I don't? What about personal files? I have backups of some of the files but for newer files I'm not sure I can even trust the backups. It's going to take me many hard hours to manually replace files with older versions, or compare checksums.

  • "An unknown error occurred" while downloading documents

    - by Scarlet Riley
    I have a 3 year old MacBook Pro and lately I've been getting an error message when I try to download something to my machine, this is what it says: Download error /Users/scarletriley/Downloads/the name of document goes here- no spaces of course! could not be opened, because an unknown error occurred. Try saving to a disk first and then opening the file. What does this mean, and what should I do to fix it?

  • Cannot find wireless driver for HP laptop

    - by rodey
    I have an HP laptop (model: dv7-1267cl, Windows 7 64-bit Home Premium) and I cannot find the wireless driver for the laptop. I am need of a different version because my wireless connection under Windows is flaky and unreliable. I have problems printing to my wireless printer and logging in to and using several sites like reddit.com, phoenix.edu and facebook.com - I get several "page cannot be displayed" messages while using my wireless connection. I disable my wireless adapter and use an ethernet cable and it all works fine. I also used an Ubuntu Live CD to confirm that there is not a problem with the hardware. This is software/driver issue. The drivers were auto installed by the OS. The Device Manager shows the wireless adapter as Atheros AR5009 802.11 a/g/n WiFi Adapter. I have checked the HP website for my laptop and they do not have wireless drivers listed for that model wireless adapter. I have also checked with atheros.com and I do not see my model adapter on their list of available hardware. Device Manager lists the Hardware ID's for my adapter as: PCI\VEN_168C&DEV_002A&SUBSYS_1381103C&REV_01 PCI\VEN_168C&DEV_002A&SUBSYS_1381103C PCI\VEN_168C&DEV_002A&CC_028000 PCI\VEN_168C&DEV_002A&CC_0280 A search for the first Hardware ID turned up this question from experts-exchange.com. tl;dr A driver does not exist for that model adapter.

  • Recover harddrive data

    - by gameshints
    I have a dell laptop that recently "died" (It would get the blue screen of death upon starting) and the hard drive would make a weird cyclic clicking noises. I wanted to see if I could use some tools on my linux machine to recover the data, so I plugged it into there. If I run "fdisk" I get: Disk /dev/sdb: 20.0 GB, 20003880960 bytes 64 heads, 32 sectors/track, 19077 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Disk identifier: 0x64651a0a Disk /dev/sdb doesn't contain a valid partition table Fine, the partition table is messed up. However if I run "testdisk" in attempt to fix the table, it freezes at this point, making the same cyclical clicking noises: Disk /dev/sdb - 20 GB / 18 GiB - CHS 19078 64 32 Analyse cylinder 158/19077: 00% I don't really care about the hard drive working again, and just the data, so I ran "gpart" to figure out where the partitions used to be. I got this: dev(/dev/sdb) mss(512) chs(19077/64/32)(LBA) #s(39069696) size(19077mb) * Warning: strange partition table magic 0x2A55. Primary partition(1) type: 222(0xDE)(UNKNOWN) size: 15mb #s(31429) s(63-31491) chs: (0/1/1)-(3/126/63)d (0/1/32)-(15/24/4)r hex: 00 01 01 00 DE 7E 3F 03 3F 00 00 00 C5 7A 00 00 Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) (BOOT) size: 19021mb #s(38956987) s(31492-38988478) chs: (4/0/1)-(895/126/63)d (15/24/5)-(19037/21/31)r hex: 80 00 01 04 07 7E FF 7F 04 7B 00 00 BB 6F 52 02 So I tried to mount just to the old NTFS partition, but got an error: sudo mount -o loop,ro,offset=16123904 -t ntfs /dev/sdb /mnt/usb NTFS signature is missing. Ugh. Okay. But then I tried to get a raw data dump by running dd if=/dev/sdb of=/home/erik/brokenhd skip=31492 count=38956987 But the file got up to 59885568 bytes, and made the same cyclical clicking noises. Obviously there is a bad sector, but I don't know what to do about it! The data is still there... if I view that 57MB file in textpad... I can see raw data from files. How can I get my data back? Thanks for any suggestions, Solution: I was able to recover about 90% of my data: Froze harddrive in freezer Used Ddrescue to make a copy of the drive Since Ddrescue wasn't able to get enough of my drive to use testdisk to recover my partitions/file system, I ended up using photorec to recover most of my files

  • VMWare shared folder out of sync

    - by JochenJung
    After booting the guest system, the shared folders are in sync and all works well. But as soon, as I make a change to one of the files on my host system (Windows 7), the file on the guest system (Ubuntu) looses its last characters and still has the old version. So the actual change is not synced. However the version on the guest gets truncated. If I delete the file on the host and create a new one with new content, everything is in sync again. It all started happening when I updated VMWare player 6.0.1. And its happening for my Ubuntu guests only (Redhat works fine). How can I tell VMware tools to force a sync on the shared folders? Host: Windows 7 Guest: Ubuntu 12.04.3 LTS VMWare: 6.0.1 build-1379776 VMWare-Tools: VMwareTools-9.6.1-1378637.tar.gz

  • Speeding up remote X sessions

    - by Alexander Gladysh
    I have a remote machine running Ubuntu 11.10 Server, to which I connect via SSH from OS X 10.7.3: Host remote.example.com ForwardX11 yes ForwardX11Trusted yes Sometimes I want to launch a GUI application there (most notably, gitk). But UI is rather slow. Both remote machine and my own Mac have good internet connection. Ping between them is about 55ms, and there is no packet loss. Is there something I can do to speed things up? Setting up some other remote desktop solution is an option, but I'd like to avoid it since I don't need this application very often.

  • Windows XP: saving large files on network share stalls

    - by mklhmnn
    When I transfer larger files (a few hundred MB) on a network share (either Buffalo LinkStation or other Windows machine) from my Windows XP Pro SP3, it always stalls. Smaller files are no problem, reading from a network share is also no problem. I already had this problem on my notebook and now on my desktop machine, so I assume that it most likely is no driver problem. Does anybody have a clue what could be the problem — or better: the solution?

  • XP shared folders not accessible after BIOS changed

    - by stijn
    Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

  • What are "build-essential" & "build-dep"?

    - by Adam Siddhi
    I am researching how to install Ruby 1.9.1 in Xubuntu 10.04 and I came across the command build-essential and build-dep multiple times. Sometimes it is followed by packages and sometimes it is both preceded and post-ceded by packages. The 2 examples I am looking at are: sudo apt-get install build-essential zlib1g zlib1g-dev zlibc libruby1.9 libxml2 libxml2-dev libxslt-dev sudo apt-get build-dep ruby1.9 and sudo apt-get install ruby irb ri rdoc ruby1.8-dev libzlib-ruby libyaml-ruby libreadline-ruby libncurses-ruby libcurses-ruby libruby libruby-extras libfcgi-ruby1.8 build-essential libopenssl-ruby libdbm-ruby libdbi-ruby libdbd-sqlite3-ruby sqlite3 libsqlite3-dev libsqlite3-ruby libxml-ruby libxml2-dev

  • Combining videos and recording sound over them

    - by Javier Badia
    This is the idea: I want to have a video where I appear twice. With pictures this is easy: you take two pictures of yourself without moving the camera, once in each corner of the room, and then combine half and half with MS Paint. What free Windows program can do this with videos? Also, I later want to record some more sound over it. Will that same program allow me to do that, or do I need something else?

  • tile a window with a hotkey on Ubuntu

    - by Eli Bendersky
    On Windows I use an AutoHotKey script to tile the active window to the left half of the screen, the right half, or a few other options. Does Ubuntu/Gnome have a program that would allow me to do that? If not, do you have an idea how to create this programmatically, or at least can point me to a resource?

  • Using a named pipe to simulate a serial port on a VMware virtual machine (linux host and client)

    - by Dave M
    Trying to write a python program to create a simulated data stream and feed it, through a named pipe, to a VMware virtual machine. The host is running Ubuntu 11.10 and VMware player 5.0.0. The Vm is running Ubuntu netbook 10.04. I am able to get the pipe working on the local machine but I am not able to get the pipe to pass data through the virtual serial port to the programs running on the virtual machine. #!/usr/bin/python import os # # Create a named pipe that will be used as the serial port on a VMware virtual machine SerialPipe = '/tmp/gpsd2NMEA' try: os.unlink(SerialPipe) except: pass os.mkfifo(SerialPipe) # # Open the named pipe NMEApipe = os.open(SerialPipe, os.O_RDWR|os.O_NONBLOCK) # # Write a string to the named pipe NMEAtime = "235959" os.write(NMEApipe, str( '%s\n' % NMEAtime )) Test to see if the python program is working on the host machine (displays 235959 if data is passing through the pipe) $ cat /tmp/gpsd2NMEA 235959 Serial port as defined in the VMware .vmx file: serial0.present = "TRUE" serial0.startConnected = "TRUE" serial0.fileType = "pipe" serial0.fileName = "/tmp/gpsd2NMEA" serial0.pipe.endPoint = "client" serial0.autodetect = "FALSE" serial0.tryNoRxLoss = "TRUE" serial0.yieldOnMsrRead = "TRUE" Test to see if the serial port in the VM is receiving data $ cat /dev/ttyS0 or $ minicom -D /dev/ttyS0 or $ stty -F /dev/ttyS0 cs8 -parenb -cstopb 115200 $ echo < /dev/ttyS0 None of these display any data from the python program.

  • USB cable model for Kodak EasyShare Z740

    - by Robert Munteanu
    I've lost the original USB cable for my Kodak EasyShare Z740, and I can't figure out which model I should replace it with. I did not find the original parts, as the camera is pretty old. I did find the cable on the Kodak site, but I I've tried both mini-USB and micro-USB and neither fit. Alternatively, bonus points for pointing out a dealer in Bucharest, Romania which has the original part. N.B. I do use a card reader now, but I find it more convenient to use the cable.

  • NTFS permissions weird inheriance (second take!)

    - by Wil
    A complete re write of my previous question, in a different context. Basically, the issue is that when I create a new user within a new group, the new user has various permissions over various folders. I have deleted the group "users" from this user object, and it is simply a member of the group "test". I have created a folder called c:\foo, when I go to effective permissions under the security tab, I can see that the user "lockdown" has various permissions. As far as I can see, there is nothing that should allow lockdown access. The moment I remove users from this list, it behaves as I would expect, which makes me believe that for some strange reason, the users group behaves like the everyone group and is controlled by the system. That being said, I cannot understand this as under the list, it is not there - and further to this, with the same permissions as the first picture, guest does not have access. This has stumped me and any help is appreciated! (Tested in Windows 2003 and 2008) edit - Should also say that if I go to Effective Permission for the group the user is in, there are no boxes checked, so it is somehow just the user that is getting the permissions from somewhere.

  • Free software for connecting to a Nokia phone to transfer music

    - by Nathan Fellman
    What free software is there for connecting to a Nokia phone? Nokia recently "upgraded" their PC Suite with a music manager that isn't compatible with my phone, and frankly, PC Suite sucks so much that I'd be happy not to use it. Is there any other free software for connecting a PC to a Nokia phone? Specifically, I'm looking for something that I can use to transfer music.
