Computer won't work past login screen

I let my comp die while it was unplugged. It hibernated then shutoff when too low. When i turned it on later it did the system resume and worked fine. Next time i turned on though it got to the log screen and when i clicked on my account it stayed on the welcome screen with the loading icon for over 5 min and then finally showed a gray black screen with the only message after another 20 mins of "Failure- Security options" Also i finally got startup repair to run and it said "Root cause found: Unspecified changes to system configuration might have caused the problem.

Repair action: System files integrity check and repair.

Result: Failed. Error code=0x490
Time taken: 460671 ms

    To Main: No i didn't install anything recently i didn't know for a fact was compatible. Already tried that and for some reason all my restore points were erased, that and i noticed my anti virus protection (avast!) has been corrupted or altered somehow.
    To geez: I did manage to get safe mode going and downloaded easybcd but following the instructions for resetting the boot files did not help... oddly enough when i brought it in to get checked it started working completely normally, go figure, and then crashed again 2 or 3 boots later. Checked event viewer log and found "bad block" disk warnings periodically all the way back to oct of last year, but saw them about every 3 seconds for 2 days straight when i checked around the time of initial crash. My OS drive is almost full of info i don't want to lose and I was hoping i could fix this somehow by myself, even though i realize it's probably a hard disk crash. Any ideas on self fix that would help me keep my data would be greatly appreciated. btw how do you copy files from a disk if you need admin clearance and your in safe mode on an admin account but it still won't let you?

From that error, it is likely one of 2 things. Either the bootloader is corrupted, which you can try to repair with the following tools:

http://neosmart.net/wiki/display/EBCD/Recovering+the+Vista+Bootloader+from+the+DVD

Worst case for a software error, clean install of Windows to resolve.

Or the hard drive is having a hardware failure and it is effecting the boot sector of the HDD. If it is a HW failure, you may be able to run diags to see if a fault is found. If the drive is bad, it will need to be replaced

    If you have file copy errors on a failing hdd, your best option is to remove the HDD from the system and attach it to a functional system (Easiest way is to use a multifunction USB HDD adapter) using a system with a functional OS, you should be able to access data that is not in a damaged sector.



    If that doesn't work, then most likely option is send the disk to a data recovery specialist (Expensive) like drivesavers.com

Thinkpad issue


You probably think it is going into hibernation mode when really your getting the black and blue screen(very dark blue) This is a result of your windows failing. Your windows has been corrupted and the fix is to purchase a new windows xp,7,or vista. If you purchased it from the store they should have you on warranty, But if it bootlegged you may have to purchase a new one.

Hope this helps ^^. Please dont forget to rate, Thanks

Make sure that your computer isn't going into Standby or Hibernate mode. You can test this by briefly pressing the power button and wait to see if the screen comes back on.

Dell D600 Battery Causes Screen to go Black


Laptop batteries normally just last for a few years, depending on usage. If your battery is almost done, it may report a 'full' status, but just have the capacity to feed your laptop for a few minutes.

You may check this by disconnecting current while your laptop is started up. If low battery capacity is the cause, the same will happen within a few minutes.

Laptops normally go in standby on low battery, to avoid data loss.

Laptop battery won't charge - Acer Aspire 4520


Since is shows it as charging then your power cable should be working. So it looks like a battery issue but batteries just don't die unless a cell inside dies then they will stop working. Try taking the battery off and making sure that the connections are clean then put it back in. If that doesn't work give the battery a good full charge then bring the battery and laptop back to where you bought it and get them to test the battery to see if a cell died.

Sometimes when I turn my laptop on, I hear the computer winding up then it stops. The screen remains blank. Sometimes I have to restart the computer 4 or 5 times before it comes on. And sometimes when it...


Yes, WinXP's relationship with your laptop's drivers has gone sour, like Pet Sematary. Bury your laptop...no wait, just reload the laptop's drivers (Dell or Toshiba or whatever) so hibernate works correctly...or un-fiddle with any hibernate/sleep/low-power utilities you use. Alternately consider that your laptop's reading signals from the battery or a cooling fan; telling XP or the BIOS that component is not in tolerable condition, and thus shutting down.

Have your feet rolfed while you fix that situation up.
