There is no software that can make the computer fail before the BIOS posts. Very little that won't at least allow the kernel to boot. So you can always at least get to the BIOS which loads from a chip, not from your drive.

If you can't, it's definitely a hardware issue and you should begin standard hardware troubleshooting on the board. If you can, boot to a utility CD/DVD and test the drive. The computer uses virtual memory which constantly shifts portions of the operating system between the hard drive and RAM. This means a heat related failure can also corrupt the data on your drive, cause restarts during RAM intensive processes like an install, and cause funny behavior.

Heat related damage is the most common problem in laptops because they run fairly hot and people like to use them on beds and couches which are soft and therefore block the vents. When laptops don't ventilate properly the memory, video, and hard drives will be the first to fail.

Be prepared to have to reload your OS and all your software if this is the case. Recovery can be very hard.

My Acer 6800 on button light comes on, wont shut off! Wont boot up all the sudden!


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

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 theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote 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 whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory 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 onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Battery light dosent work during charging or fully charged. Light comes up at times. battery level is either not indicated properly


In most models the battery light is displayed when it is charging with a possible blinking when it nears charging and it cuts off when the charge is full.
So if your laptop shows that the battery is charging in the task bar- bottom right, then you can ignore the issue unless your laptop is in warranty and it can be done free of cost.
If you open power options in the control panel the charging will be displayed , if this show Ok then the fault is the hardware circuit issue on the mother board power section.
