Question about IBM ThinkPad T40 2373 Notebook
I HAVE MY LAPTOP AND WHEN I TURN IT ON IT WILL NOT DISPLAY. THE POWER LED COME ON AND THAT IS ALL THAT HAPPENS.
CAN YOU ADVISE WHAT I CAN DO THE RUN SOME TEST
Get to the mainboard
there is a jumper near the cmos battery usually shows the
word (jbat) near it , try to change its position for some
seconds while power is off , this way will clear cmos and set the
mainboard bios to default settings.
start the system hit delete or F2 to enter setup then exit saving changes.

I have repaired count less T40's with this issue, it's normally caused by a bad Ram chip, try pulling one of the sticks out (if you have 2) and powering on with just one, if that doesn't work try the same chip in the other ram slot, then try the other ram chip. I maybe a bad system board, but most of the time it's the ram.
