Remove the hard drive and RAM. See what it does. It should go into BIOS and complain. If it doesn't you have a motherboard issue as it won't POST.

Try taking the batter out and booting using just the power cord and Vice Versus'. Also when the power is plugged in does the charging light (Battery Indicator) blink or light up? If you know the Power Supply is good, then the Mother Board may have fried. If it's under warranty, take the Hard Drive out and send it in.

Power problem


If you have already tested and changed the RAM then from your description and the things you have done, it looks like you have a faulty motherboard.
This computer is too old to consider replacing the motherboard, if you could get one. If it was me I would put my money towards a new one.
You could use the hard drive, put it into and USB hard drive adapter case and use it as an external USB hard drive.

I have 2 ibm thinkpads t40, on one of the systems the lcd inverter and screen get no power but when i take the lcd and connect it to the 2nd ibm tkpad it works fine, What would be wrong with the one lap...


On the second Thinkpad laptop, that doesn't show a display with an LCD screen.
Plug a VGA monitor into the VGA port on the back of the laptop.
Hold the Fn key down, tap once on the F7 key (Toggle your display over to an external monitor)

Give the VGA monitor a few seconds to come on. (It's a VGA monitor)

Do you have a display on the external monitor? No? You May have a bad GPU then. (Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU )

Fix? Change out the motherboard. Possibly Ebay has one, dunno.

VGA monitor has a display? Then you may have a bad Inverter. The Inverter provides power for the LCD screen. Inverters go bad.

Are both Inverters the same? (Laptop to laptop)
BE SURE. The Inverter MUST match the LCD screen!
Check the numbers on both Inverters. If they are the same, switch the good one over to the 2nd laptop. See if you have display now.
No?
Then it's the GPU.

IBM Thinkpad T40 Powers on but only the fan works nothing else


you may have knocked your hard drive lose
are you getting any error messages
you can take the hard drive out put it back in and start up pc to see if that helped.
If the hard drive was'nt the problem you may have caused something else to be lose.
Shut pc down and try hard drive first
