Re: wont power on
Try powering the system on with only the AC adapter, see if you get any power indications.
If you do not, then the system is not getting AC power.
See if the power adapter has an LED on it and if it is lit with the computer disconnected. If the LED doesn't come on at all, replace the adapter. IF the LED is on with the computer unplugged from it, then goes out when you plug it in, then try a new AC adapter.
If a new AC adapter doesn't resolve the problem, then you may want to look into buying a new computer as replacing the motherboard on this system may cost more than replacing the computer with a new system.

When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.
Remove all of the ram, turn the laptop on if it does not beep you have a bad motherboard. If it beeps replace the memory and remove the hard drive turn on the laptop and see if it posts. If it posts without the hard drive then the hard drive is bad. Otherwise it is probably still a bad motherboard.
try to turn off the laptop and remove the battery and the power cable. Then press and hold the power button for 5 secs. Then reinsert the power cable and battery on to your laptop.. Turn on the laptop, and if the cpu fan cycles on and off, that means there is problem with the fan and also the power supply of your laptop. Call Acer to replace the power supply to stabilize your laptop's electricity...
I had trouble looking up that model on the HP page, but you should check this page and see if this model is affected by this NVidia litigation. If it is, you can get it fixed/replaced on NVidia's dime.
If you feel that the fan does not move the all, that is the main cause of your problem. To reseat the fan, kindly turn off your laptop, remove cables & battery, press and hold power button for 8 secs, remove the screws at the back of the battery, remove the hard drive, remove the optical drive, and then reseat the fan. Then insert back the optical drive, hard drive, screws, cables and battery then turn on the laptop. IF it did not work, you need to call Samsung to replace your fan.
disconnect the battery from the laptop and only hook up the ac adaptor.
Turn the laptop on and if it still cuts off after 5 seconds then reseat the memory back into its slots.
Also make sure your air vents are not clogged with dirt or dust as lack or air flow can cause the laptop to shut off.
If that doesn't do it then take out the hard drive and dvd drive and turn on the laptop.
If the laptop still cuts off then it has to be a faulty motherboard at that point which means to much voltage is going thru and the components on the motherboard are not regulating it properly.
