Thinkpad t20 freezes on reboot - Computers & Internet

Your CMOS battery is low you need to replace it ASAP

The 2647-27U requires PC100 Type Ram, not PC133.

Hi, During the boot at the THINKPAD SCREEN press the Thinkvantage key ( Blue button ) it will launch rescue and recovery and allow you to reboot factory. This only works if you did not corrupted/deleted the rescue and recovery hidden partition on the HDD. Otherwise you will need the rescue and recovery CD to proceed. IBM/Lenovo support should be able to provide you the CD. Might be a defective hdd aswell, in this case to make sure you can run a DFT test, www.google.com -> Look up for " Test DFT " ( Drive fitness tool from hitachi, will make an hardware diag if hdd failure - error code 0x00 = everything fine, other code = Issue - You can look up for accurate code explanation on hitachi website ) thanks and have a nice day J-

is there an indicator lights that acknowledging there is power or none?

the internal coin cell battery has gone bad, it needs to be replaced.

Sounds like a virus. See is you can start it in safe mode. If you can, do a virus scan.



Let me know if your problem is solved and rate me as FIXYA!

Remove the cmos battery from the motherboard, small round, for about 5 seconds. Replace & reboot. This will clear passwords. Hope this helps.

Hi,

For security reasons this solution can't be given out, you must re-install the Operating System to factory settings.

Please rate my solution when possible....!

Good Luck....!

Cheers

your computer is full of virus better install a anti-virus and scan your computer for virus and delete them.

This error can be caused by one or more of the below possibilities:

HDD
Power suply
Ram
Cooler dont work propertly
Or you are infected with virus
But most of those problem happent when HDD is damanged!
