My t20 comes on sometimes, and after it's been on for a while and I restart it, ( after an update, for example) it won't come back on...and I don't know for sure if the fan is coming on when it's running, either
If you are talking about the Boot, HDD, Bios password, then the only one way to recover it is to implement a chip on the systemboard to shorcut the protection or to contact Lenovo for a systemboard replacement.
Unfortunalty, no other ways other round.
Thanks and have a nice day
How did you set the password?
Did you buy this laptop from someone?
If you did you need to get the password from that person.
There is no backdoor password available and removing the BIOS battery will not remove the passowrd because the password is stored on an EEPROM chip.
You need the password to boot up the laptop and then into the BIOS configuration to remove the power on password.
The Innaccessable Boot Device message means one of 2 things:
1: your hard drive has died - not much here, must replace drive.
2: The master boot record has become corrupt. Without any media, this will be hard to fix. You will need to boot to the Windows CD and either run the recovery console or perform a windows repair to fix this issue.
