Question about IBM ThinkPad T22 2647 Notebook
When I boot the laptop, the power lights will come on for a short time but then the computer will not boot up. All the power lights will come on but then just the first yellow and the last green wil stay on. I have replaced the battery.
That model is an older IBM, the CMOS Battery may be dead by now. That has been my experience.
Try this - replace the cmos battery first.
The settings may not be able to be read. So laptop don't know what to do after P.O.S.T.

This can be caused by:
1.The monitor is not connected properly.
2. Bad hardware
Verify that the monitor is properly connected in the back of the monitor as well as to the back of the computer.
If the connections are OK it means that monitor or the video card is probably damaged. To test which component is dameged connect a different monitor to your computer or connect your monitor to a different computer.
If the other monitor works on your computer it means that your monitor is bad and if your monitor works on another computer it means that you probably have a damaged video card.
Ensure that all cables are correctly connected and pushed in firmly. On some systems the mouse and keyboard connectors are very similar and next to each other. Ensure that the mouse cable is plugged into the mouse socket and the keyboard cable into the keyboard socket
Check that system unit are plugged in. Check the power socket by plugging in a lamp and ensuring it works
Check that there is power to the system unit. If you are unsure or do not know how to check this, either change the fuse or borrow a suitable lead from a colleague
Switch the PC on, watch to see if the keyboard lights flash and the fan is blowing air out of the back. The hard disk light should also flash on and off during the start up process.
If the system beeps several times when powered on carefully count the number of beeps - some systems use this to indicate the sort of error that has occurred, but remember that some computers produce one or two beeps as part of the start up process.
I you hear an unending series of long beeps, which usually means your mobo is not seeing the memory sticks properly. A short series of one long and three short beeps usually indicates a problem w/ the graphics card. Taking mem sticks and/or gfx card off and resetting them, with some contact cleaning if needed, generally solves the problem, provided, of course, none of these parts are damaged.
Don't forget to unplug the power cord before removing/inserting the memory and video card, otherwise you might end up killing them.
Let us know how things turn out and don?t forget to rate the posting.

Hello, the symptoms your describing sounds like a bad system board. Can't say in all my years of repair have I heard of "cleaning" RAM, but I guess you never know. This model is known for its "weak" system board. You can find more info on that on IBM's site.

If you are hearing beep codes you can repost it here... anyway probably the problem is not in your power options... try removing your RAM modules and use an eraser to clean contact points the use a non-static brush to clear the dirts of the modules... securely firm the RAM and try booting up you unit...
rank me if this helps...
