Specs: Windows XP home SP3., 1024MB DDR2 SDRAM T5900 @ 2.0 GHz
I have a Gateway MT6840 notebook that will not turn on properly. I took the hard drive out and the battery and left it alone for a few days and when I put it back together it powered on like it should, but then it froze and I forced it to shut down. Again it wouldn't power on. only the LED light would glow when it was plugged to charge. The battery is full. Anyways, I did the same thing over again. I Took the hard drive out and batt and let it sit again a few days, and I put it back together, it turned on like it should. But it froze again and i had to shut it down. What do u think might be causing this problem?

Try blasting compressed air thru the cooling vents.

I tried that once and it still wouldn't turn on. I also used a clean paint brush to dust the inside, although it did not need it. Still that didn't help. Only when i took the hard drive out and let it sit for a few days. I tried to turn it on without the hard drive just to see what would happen, and nothing.

What do you mean when you say it won't turn on / power on?
It won't start up at all, or it does boot but Windows won't load normally?

If it won't start up at all.....

There may be something wrong with the main battery and/or it's too old and/or you have a charging connection problem.

See response 1 in this:

Correction for that:

The jack in the laptop should move when you wiggle the plug in the jack.

should have been

The jack in the laptop should NOT move when you wiggle the plug in the jack.

A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

For a laptop, you must remove both its main battery and AC adapter before you do that.

See the Owner's manual for your model if you need more info about removing and re-installing the ram module(s).

I also would suspect a dying battery or a loose AC adapter cable connector.
