SOURCE: IBM ThinkPad T22 won't turn on

You have what is known as the Blink Of Death (BOD). There are several things that seem to work, but none of them ALWAYS work.
What works most of the time for most users seems to be the following. Remove the main battery. Remove the AC adapter / charger. Press and hold the power button for at least ten seconds. While holding the power button down, plug the AC adapter / charger into the unit. If you are using a Ni-CAd or LI-ON battery, you should NOT leave the battery in the computer all of the time the AC adapter / charger is connected to the unit. NI-CAD's develop a memory of sorts with repeated short re-charge cycles. LI-ON batteries a limited number od re-charge cycles and they have microprocessors inside the battery housing that are there to attempt to evenly control the charge to the individual cells. Google Blink Of Death for more information.

Good Luck,

If your saying that the battery is blinking. In my opinion it sounds like it could be a dc jack charging issue. Lets first start with doing a hard reset of your device. Hold down the power button for 30 seconds without the charger plugged in. Then reconnect the charger and try powering the device on. Try to identify if there is a pattern in which the battery LED is blinking. Does it just consistantly flash, Or do you notice it blink three times and then pause. We can try to troubleshoot this further if you have any issues after gathering this information.

Reboot IBM think pad A21e

There are two possibilities, the hard drive has issues or windows has corrupted files. If you have a cd installation disc for a fresh install, try to see if the operational system will load, no change! the hardware should be checked in the event it needs to be replaced.

Worked fine yesterday - will not turn on today - kitchen

When you say the machine is dead do you mean you are getting no LED lights at all or do you mean it is not booting up? No power and no post are two different things. With no power you get absolutely nothing at all. With no post you may have some LED lights but nothing comes up on the screen. You said power and power supply tested ok. How are you testing it? I need more info please.

It sound's Like the AC power that is sawder on the mother board is broken that's how it explains some times it works and some times it doesnt. I would try taking it to you local PC shop. Ask them to check your AC Power Outlet on the motherboard.

DC400 not powering on

It could very well be a problem with a blown fuse/capacitor within the power supply, since these things are smaller it would be a good idea to take it to a local tech to have it opened up and checked out.

Good luck!
