If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

If the the ram is the problem of your system, there should be a power on light on the system. indicating that some of the component of the system is not working correctly. But since you mentioned there is no light, it is the possibility that the problem is the motherboard itself.
The problem is that you need to boot up the laptop with the CD as the first boot device so you can then install Windows XP.
If you press F12 a boot up you will get a list of alternate boot devices oher than the hard disk as the first boot device, which was set up in the BIOS. Select the CD as the first boot device and when prompted press the space bar to start the CD.
This is a common problem, that involves the power management system on the motherboard. There are few places that can fix the problem, and they will cost you more than replacing the motherboard. I'm going to suggest replacing the motherboard, it's much cheaper and easier than trying to repair the old board. You can find one at a decent price on Ebay. Here's a link for the hardware maintenance manual for the T20 if you would like to replace the board yourself.
sounds like there is a problem in the hard drive. Go to google and search for Hirens Boot CD it is about $10 but its well worth it. Boot from this CD and run the Check Disc Utility(chkdsk) and some of the virus tools, this might fix the problem, otherwise it sounds like a bad CPU or faulty RAM may be causing this broblem
If I understand you correctly you turned off your laptop and since then have not been about to boot up normally, occasionally getting a blue screen. Typically the blue screen also has some type of error message, can you tell us what that is?
You indicate that booting from the CD drive is not possible, is that because you don?t have a working drive? In any case this sounds like a problem with system files or possible a device driver and a CD drive is almost certainly going to be necessary. Let us know the answers to this questions and any other pertinent history relating to this issue and we?ll see if we can help.
