Simple problem? Pls help: Thinkpad T410 boot error

2016-07-03, 16:29 PM

I have a Lenovo Thinkpad T410 which I left outdoors overnight after a BBQ... No rain but likely some humidity.

 

Symptoms?

Initially, screen remains black, nothing happens upon pressing power button. However, computer is still alive since power button is shinin

- After Unplugging/reconnecting the CMOS battery cable: machine booting, showing following two errors after some time:

0271 Date and time error—Neither the date nor the time is set in the computer.
[Solution in the manual]: Run BIOS Setup Utility to reset the time and date.

0251 System CMOS checksum bad— Default configuration used.
[Solution in the manual]:
1. Charge the backup battery for more than 8 hours by connecting the ac adapter.
2. Replace the backup battery and run BIOS Setup Utility to reset the time and date.

 

I tried:

  • Removing The backup battery (CMOS)
  • Replacing the backup battery (CMOS) - I bought a new one
  • Battery, only running on DC-power
  • HDD
  • RAM x2
  • DVD-drive
  • Keyboard
  • Power button discharge as suggested on various sites to discharge (or whatever) the power; To press the power button 10 times followed by pressing it for 30 sec...

I tried to reset the time in the BIOS, however, I'm unable to navigate with the keys> nothing happens when I try going up and down between the options with the keyboard - I tried pressing many keys simultaneously, and I do get the familiar beep when you press a lot of keys randomly, so the keyboard is working fine. Then I noticed incidentally that the screen light goes up and down if I press the keys changing this, meaning it's like the Fn (function) key is constantly pressed. So I also tried cleaning the keyboard and removing the CTRL and Fn/key but this didn't help either.

 

In fact, my problem is identical to those in: https://forums.lenovo.com/t5/ThinkPad-T61-and-prior-T-series/T43-Hangs-on-boot-up-screen/td-p/71260

The solution there was to try pressing the GPU, however, its not dedicate one, can't see that would help?

 

Many many thanks!!
