If you,ve sat on the laptop, i don,t think you,ve completely destroyed it.
If the screens intact, then you,ve possibly broken the lid-catch switch.
Where the lid-catch contacts the base of the laptop, theres a switch mounted on the motherboard, this alerts the laptop to shut-off the screen, as the lid is closed. If your lucky, this may be a daughter board, connected to the motherboard.
you,ll have to find a service manual for, your model and go from there.

Hi I could use some advice, I have an Acer Aspire 6935g which died while i was out of the house for about 10 mins, came back and it had turned itself off with no signs of power at all, not even the usual...

Hello Kelpi,

Hmmmm. So with the video card installed, no life, no joy. With the video card out, signs of power, but no joy. Since this just sort of 'happened' out of the blue, it sounds more like the card than the mobo. First, inspect the video card for signs of scorching (look at the chips on it) and any 'brown' areas on the card which may have happened as a result of excesive heat. Also, try cleaning the contacts on the card (and the mobo socket) with a pink pencil eraser to remove oxidation - dont rub so hard as to remove the gold plating on the contacts if present.

If there is a vga port on the laptop which is not attached to the video card, try booting it up with an external monitor connected. I haven't seen one of those laptops for a couple of years, but some research showed that some of them have an onboard intel gpu and pci express support for the discreet video card. You may be able to get video with an external monitor, go to the bios, and change the primary graphics to onboard.

Here's another option: Take it to an authorized Acer repair shop. They can order a video card from Acer and if it doesn't fix the issue, they can return the part to Acer within 15 days (that's the return policy in Canada) You may have to pay shipping and a restocking fee, but this is still an option. Also, Acer is very reasonable with their repair rates. You may be able to send it to them directly and have it repaired for a flat rate. Acer is also very reasonable with their parts pricing, so if the video card option doesn't fix it, you can likely get a new mainboard for $100-150.

Hope this helps! Let me know how you make out.

Sounds as though your ac adapter is bad.But it could also be the power jack where the ac adapter plugs in also.

Won't turn on even with power cord plugged in

By dumping the power while running you have trashed your Operating System or blown up the Ram

Insert your OS disk and see if it comes to life , if it does then you may have to try a repair from the OS installation CD

If you have popped the Ram then the only solution is to get it checked out on another PC

No signs of power on my gateway mt3705

The power supply provides only 48V (or what ever is listed on the back) but the computer breaks out +12 -12 +5 -5 etc and if that power regulator is damaged it will not come on.
Remove the battery and unplug, hold the power button on for 2-3 minutes, plug in ONLY the power cord and press the power button.
Most likely if you don't get any text on the screen the internal power regulator/converter is damaged.

HP notebook will not restart after closing cover overnight

Think it went into hibernation. Unplug from a/c adaptor, and remove the battery. Let it sit for 2 or 3 minutes, then plug in a/c adaptor and turn the unit on. It should reboot like new.

Laptop wont turn on

You may check if the charger connection to the laptop is secured and doesn't have any problems. If the laptop doesn't show any sign of life,no led flashing, no nothing it is probably that your charge circuits or power on signal circuits are burned or broken. It sounds strange but they don't need a special motive to do that, they can simply die out. You will need your laptop dissasembled for this job and some knoledge of laptop electronics however. If you feel that this is not for you a service center can check the problem. Be carefull to specify exactly the simptoms you encounted. In worst case scenario they will asume your motherboard "dead" and propose a replecement. Be patient and try other service centers if this is the case.
