helo

go to the link below to get further assistance
but basically to reset the password, follow these steps.

If the Power-on password (POP) is forgotten and the Supervisor password is known, simply go into the ThinkPad BIOS setup utility and reset the Power-on password, otherwise try the following:
  1. Turn off the computer.
  2. Remove the battery pack.
  3. Remove the backup battery (CMOS battery --size of coin- located on mainboard, requires you to remove the plastic cover on rear on computer)
  4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed.
  5. Reinstall the backup battery and the battery pack.
    Note: Some ThinkPad systems have the ability to reset the Power-on passwords in the ThinkPad BIOS setup utility if a Supervisor password has been set.

It sounds like your system board is gone. It will need to be replaced. A used board goes between 150 -300 dollars. For someone to check it will still need to be disassembled.

remove the battery large.
then run on AC pack only
#1 top failure of all mobile PC is that battery, so unplug it
then test with AC pack only.
work now.? and all vents must be clean, end to end. not just fan.
there i no fuse it uses current regulator, imagine genius magic electronics fuses that never blow out, and bingo.

OK big battery out, an RTC coin cell fresh.
then fan blows.
next is BIOS, do the BIOS screens work if not the mobo is dead.
have 2 RAM stick on the 2 slots>? try one at a time
run the PC with all modules removed, (options)
remove hdd?
remove, dvd drive.
think like this. Get bios working first
learn that modules can short, and when they do the power regs shut down.
so we unplug all things to the mob,
until only 1 ram and cpu remains.
see? (this is called power overload fault isolation tactics)
even the screen only can be dead, you never mention text showing
you can test the mobo with external screen via that rear (?)_ VGA jack what if that worked, did you learn something here, sure.
this pc has tons of modules to pull, even bluetooth. wifi, sound and more. if you look at all parts inside or sold by ebay, bingo. lots

It helps to know what device model and OS you are using though the following steps for changing from pattern lock to slide are for Android OS 4.0 (Ice Cream Sandwich):
1. Unlock your Android device
2. Find the Applications menu and select "Settings"
3. Under the "PERSONAL" group, select " Security"
4. Under "SCREEN SECURITY" group, select "Screen Lock"
This will ask for the security pattern first.
5. The options for screen lock will appear, select "Slide" and you are done!
Hope this helps.
