Question about IBM ThinkPad T22 2647 Notebook
When i press the power button it just blink and theirs nothing on the screen
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.

Well,I left my computer sitting without the battery for about 1 week inserted it and it worked well for about 1 hour so i had enough time to save important information,i hope this helps if you have info you need to access important things.

Try removing both main and backup battery (under main battery, remove 1 screw then gently remove - made need to lift out a bit w/small screwdriver or paperclip) then let sit with no power 24 - 48 hours. Then leaving batteries out plug in to AC and try to start - you should get the BIOS error that time is set wrong go ahead and set this and finish booting and if everything works, DO NOT SHUT OFF but back up critical data. Then turn off and see if it will restart. If it won't it is probably a bad capacitor and leaving the batteries out allows the cap. to fully discharge. I am searching for more info but haven't found a sol. yet so you either pull the batteries and wait 2 days or leave the laptop on - screen open but you can let the screen turn off just don't let it hibernate or go to standby.

1. Reseat the memory chip(s), and try again.
If that doesn't work:
2. Remove the battery, Hard Disk drive, wireless card, any PCMCIA cards, floppy drive, CD drive and all but one memory chip. Try again, and see if it comes up any farther.
If that doesn't work:
Swap to the other memory chip (if you have a second.one)
At any point, if it comes up to further than it did, start replacing one item at a time. This should help you find the bad part.
If none of this works, get back to me for more ideas.
