    My IBM Thinkpad R40 won't start up either. Mine is type 2723. I do believe that the power supply is good. I have turned it on with just the battery in, and I've turned it on with the AC adapter plugged into the wall without the battery inside of it. So I think both power supplies are good.

    When I press the power button, all of the lights come on (battery, caps lock, number lock, and sleep (the crecent moon one), except for the wireless connection light and the cylinder-looking light, which I think is usually the one that blinks when the computer is "working" or loading something.

    So, I press the power button and most of the lights come on for a second, then go off leaving only the battery and the zigzag in a circle lights on. If there's a disk in the laptop, it spins for a couple seconds then stops, and the same goes for the fan. It comes on for like a second, then it stops. The screen never comes on.

    Please Help!!! If anyone can lend any advice at all...

    I've tried creating a boot-up disk, but your screen has to actually come on for this to work. My computer won't come on, so I can't even attempt to get it to boot from the disk. I've also tried that press the power button 10 times in a row, holding for 10 seconds each time, then 30 seconds on the 10th time. This has not worked for me.

    Some people have said that pressing down on their computer in certain places has gotten it to start, but I don't know where to press.

    Please help, anyone... :-(

Since I haven't heard back, I'm going to give you a couple of thing to try. Check the power supply with an ohm meter to see if it's getting power to the machine. If there are no lights at all and the power supply is good, then the problem is with the motherboard. Have a tech check it to see exactly where the problem is. More than likely it's with the power management chip, if so, then the board will need to be replaced.

Blank screen ibm r40e

This is generally a memory problem. Remove the memory, and try them one chip at a time in each slot. If the memory isn't the issue, then try removing the battery and starting with the supply only. Both battery and memory can cause this, but the beep code is generally for the memory, no beeps with the battery. If both check good, then test the power supply with an ohm meter for the proper output. If these three check good, then the problem will lie within the motherboard, and you will need to take it in for a professional diagnosis in order to track down the exact problem area. You might also look on IBM's support site for the beep/sound error codes and any troubleshooting for the exact code you have.
