When I boot up the screen remains blank, although the power light is on and the drive seems to be spinning. I tried unplugging the power, removing the battery, replacing the battery and re-booting but still no resolution. Any other pointers would be greatly appreciated. Thanks!

If it seems like the computer booted up all the way except the screen is blank.

If so try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok and works, then the video card inside the computer is good, but the original monitor is bad. If the Borrowed monitor does not work, then the video card inside the computer is bad.

If it does not seem like the computer booted up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

It sounds like that memory should be compatible with your tablet PC. It may be a bad memory stick -- try to replace it with a different memory stick (preferably from a different manufacturer) and see if it still gives you the same problem.
If you didn't have this problem before you installed the new memory, a different memory stick will likely correct the issue. You can also try removing the new memory and see if the PC boots up like it should.

Yes, if the CPU/motherboard will not POST (Power On Self Test), then changing the CPU is the only thing that you have not tried.

Do you have another monitor to test your computer? Looks like a surge went into the computer display and damaged the video card.

Re : When i press the power button, the lights all light up, the cd rom drive spins for a second and that's it. No fan, No Post, Blank Screen. After a few seconds, it shuts off and then turns back on.

That is generic hardware fault, any faulty device can cause the problem.

The motherboard must be started with a minimal set of devices to troubleshoot.

Start motherboard with only CPU, power adapter connected (faulty battery can cause the problem), heathsink, display and one memory stick. Keep unplugged HD, optical units, keyboard, minipci cards etc.

If problem persists, eventually test the motherboard using a post card(PCI & ISA PC Diagnostic POST CARD MOTHERBOARD TEST CARD) to ensure that new motherboard is not faulty, and then if cpu has not been replaced with the motherboard, replace CPU.

plz try by resiting the ram

try on other tv

there is a hole on the back usually goldish inside take a pen push it in there hold for a couple seconds and press the power button

this is normally motherboard or powe side problem check your motherboard
