• Computer HP laptop dv7 randomly stops, error Kernel-Power 41

  So my new laptop has stopped 3 times in the last 2 weeks, randomly.  No BSOD, no nothing, just nearby.  kinda like if you have unplugged or removed the battery.  He always turns on no problem.  All 3 times it was plugged in and the battery is charged.  In the event log is as follows:

  3 event errors are the same.  By chance I hear that the first accident was while I was surfing the net with IE8, it was the only common thing and 1 single tab - on yahoo.com.  The next crash I played Stalker through Steam.  And finally, when I had only Firefox running with 1 Tablet and I was not even touching the keyboard or the touchpad, I just read the screen, lol.

  Any help would be greatly appreciated!

  I thought I found the problem, but it always stops at random.  I called HP and they said that it's probably the motherboard.  I think that's their standard answer if they have no idea what is the problem.  In any case, I have to send it back, I got it for Christmas.  Now I have to use my old laptop for several days.  I am not happy that nobody cares, have a good day.

• X 201 random stop with new battery

  Hi all

  I use my X 201 for 4 years now without any problems. The original battery is tuyanteries out, I replaced it with a 9Cell Duracell (Sanyo) one.

  Since then and only when I use the new battery, this disconnected, my laptop randomly stops without warning. No overheating problem.

  Win7 newspapers pointing powerfailure (power core to restart shows error 61)

  (I have no idea) the reason for this behavior odd ii) the remedy

  I would gladly buy a new Lenovo battery if only I was sure to solve the problem...

  best regards and thanks!

  Christophe

  .

  Hi all

  I contacted the community because my new Sanyo battery would be suddunly and turn off at random, causing of course my Thinkpad X 201 to close.

  Here's what I found: aft uf the battery, there is a slide button to lock it once you insert it into the battery tray.

  On battery 6cells, simply insert, yo hear a click, and the battery is locked.

  On the battery 9 cells (at least on the shot I bought) the sliding button must be moved manually to the "Locked" position If you don't move it, the PC starts normally, but stops abruptly after 10, 30 or 50 min, come anytime.

  Problem solved. I hope this can help!

• HARD drive randomly stops

  Then, I had this problem for about two months now, increasingly more often.

  My laptop (Pavilion Dv6 - 1350eb) would just freeze or stop for no apparent reason. because it was during the course of the demanding graphically programs (inventor/autocad) I took the laptop overheated.

  then it started to happen when my laptop fell asleep - it would break, en no error no reports were given.

  last month, that accidents are extremely common, sometimes my laptop does not even (HDD led flashes orange)

  and I sometimes get error reports.

  disk tried to write in the ROM, irl not equal and other errors
  .

  After reinstalling my OS, the problem persists, so that's where I think that the HARD drive is broken - analyzes the hard drive with the startup check fails every time.

  So now, I bought a new HDD (same brand, same model), and my laptop does exactly the same thing; randomly stops running, no error message, hdd led, flashes orange when restart.

  Any ideas what this could be?

  Baru,

  I'm glad to hear that you're getting it taken care of.

  Accumulation of heat and the failure of HARD drive are some of the main reasons for freezing.

  The heat can be the thermal paste that need to be replace, the fan who needs to be replaced or maybe even just to clean the system with a can of compressed air and get rid of dust inside the system.

  I would like to know how everything goes.

• STOP errors and gel on WinXP Home on Pavilion laptop

  Hello

  I'm having a problem with a laptop HP Pavilion ZT3000. I started to have errors of random stop (STOP 0 a, 4th STOP, STOP C1) or the computer just freeze.

  I did a check through the memory with Microsoft memory diagnostic, as well as MemTest86 +.  No errors not found after vigorous testing.

  I also checked the hard drive for errors. After a test is important, some not found errors.

  I can't measure the temperature of the CPU with a software like many downloadable programs do not read the temperature of the CPU of this HP Pavilion chipset platform.

  I have completely deleted the computer and installation of Windows XP from scratch. Subsequently STOP re error - manifest.

  I even tried to install Windows 7 on this system, but which did not succeed because there aren't has no drivers for many functions on Board (WiFi, sound, etc.).

  What else can I do to try to resurrect the Windows XP operating system for this laptop? I wouldn't like it undesirable because of these stop errors. In safe mode, the computer plant to the same extent, but safe mode isn't as usable as Normal XP mode.

  Thank you

• Why has my laptop started to randomly stop before turning off

  Original title: computer power questions

  Why has my laptop started to randomly stop before turning off? I had no problem with this computer at all for more than a year. I tried to run all the updates available, but of course, it turned off before she finished. Sometimes it will run fine then others that it is a nightmare. can anyone help please? I would be very happy to help!

  Hello

  Could be heat related - try using a small fan to blow into the air intakes to see if that helps.
  It is just like it loses power or stop it in the normal way?

  Remove ALL power and reinstall all the memory cards and cables (both ends where possible).
  in fact, remove and replace - don't do not just tight. Remove the dust bunnies and clean the
  air vents. Check that fans are working (before and after opening the case). When your laptop on all the
  You can do is to reinstall the memory and clean the vents (still may try to add a small fan as a
  test).

  This sounds like material so if the above does not help you then probably need the help of a
  real computer store (not of leeks and glances at a Best Buy or other department stores) or the system
  Support from the manufacturer.

• Computer daily and random stops with laptop Vista Ultimate

  I use a laptop Toshiba Qosmio with Vista Ultimate.  The machine stops completely randomly on its own and I have to restart - which can take up to four minutes - I get a message in an unexpected way, the machine closed and restarted in XXXX seconds.

  This morning I got Excel (2007) and Word (2007) open and use my webmail (work and personnel).   I use Internet Explorer.  It is quite frustrating and I don't know where to start to try at the source of how correct the problem or address.  The machine is not quite 3 years and Vista Ultimate came installed on the machine.  I installed the Service Packs 1 and 2 on the machine.  I'm also trying to determine if I should Windows 7 would avoid most of these stop random downs.

  Satellite A100-S2211TD, OS is Windows XP Home Edition of recovery disk,

  I have updated the BIOS to 2.20 and laptop was working fine. The old installation of Windows factory has worked well.
  After a few weeks, I tried to use the recovery disk to remove the noise from the HARD drive.
  The recovery of disk task completed and the computer restarted.
  I got the stop error message
  STOP: 0x0000007B (0xFA335528, 0xC0000034, 0x00000000, 0x00000000)
  I removed the memory that I have entered over the past two years and return the PC in the factory scene.
  However, recovery will not be finished (he worked to restore).

  I am able to boot in dos with a separate boot disk (Dr. back, windows does not start, not even in the safe control mode) and I did chdsk of the disc and disc is fine.

  I've never used before recovery disc, the only thing different is BIOS 2.20 instead of 1.50.
  WEB of TOSHIBA said that if you upgrade the BIOS most 2.00 you can not return to 1. XX

  Hello

  The A100-S2211TD doesn t support the Intel Chipset!
  This laptop was equipped with the ATI graphics card and the graphics driver on the Toshiba page contains us the graphics driver and chipset driver!

  Have you received 100% good recovery CD?

  In your case I would try to install Win XP from the Microsoft CD to check if the same error would appear if no drivers are included in the CD of the OS.

• Equium M50-244 run the Stop error after DVD playback

  If anyone can help with tips here. All watching my laptop DVD crashes with a runtime stop error which forces a closing down of the system. It's then a capricious beast in reverse that the screen remains blank and does not start start. When it decides to launch it is slow at the start and has on occasion crashed again. Report error screen Windows indicating that this is a MISTAKE STOP RUN is launched. On the game, the system slows down considerably, which means that next time I want to spend on the laptop should I go through t - he or she does not start into a nightmare. This is starting to get a little boring

  Hello

  With RUN the STOP ERROR do you mean the blue screen of death (BSOD) or what?
  What DVD player program did you use?
  Have you tried using different applications such as WinDVD or PowerDVD?

  However, I think that we should focus on the system slow downs.
  This could be caused by the high temperature if the temperature rises to a higher level, the system attempts to limit the performance of the processor.
  This reduced heat production, but slows down the performance of the laptop

  Overheating pourrait causes that the shut downs as s possible BSOD checks then perhaps you should try the cooling modules if they work at full capacity.
  Cleaning of the fan could probably contributes to
