Laptop doesnt stay on

check power settings by opening control panel -> power options. Check when is the computer set to go to sleep and when to turn of the display. This might be caused by Windows power settings that put the computer to sleep to save power.

Most laptop batteries have a life expectancy of two years or 400 to 450 charge and discharge cycles. After this time, the battery may lose the ability to charge or to hold a charge for substantial periods of time. When this happens, it's likely the battery needs replacement. However, troubleshooting can narrow the problem and ensure you are not wasting money on a battery replacement.

Check Power Adapter Turn the laptop off. Remove any power cords or power sources. Separate the battery from the bottom of the laptop. Slide or press the locking mechanism to unlock the battery. Slide the battery out of the battery compartment. Plug the power adapter into an electrical outlet. Insert the opposite end of the adapter into the charging outlet on the side of a laptop. Power on the laptop. If the laptop does not turn on, the power adapter is not correctly working. If the power adapter is not working, the battery can not charge. Replace the power adapter. If the laptop powers on, the power adapter is properly working. Clean Battery Contacts Turn the computer off. Remove any power cords or sources. Take the battery out of the battery compartment. Dip a cotton swab in isopropyl alcohol. Rub the dampened swab on the battery compartment and battery contacts. Dust and buildup can prevent battery contacts from properly charging. Slide the battery back into the battery compartment. b> Charge and Test Battery Plug the power adapter into the laptop. Charge the battery for six hours. Remove the power adapter. Turn the laptop on. If the laptop turns on and stays on for at least 30 minutes, the battery is holding a charge. If the laptop doesn't turn on or the battery doesn't power the laptop for at least 30 minutes, the battery should be replaced.

You don't have a real serious problem. Just use the Power Cord. Now if the Power Cord does not work, that's a real problem. If your power cord is good and you can use your laptop with it, then the problem is your battery is bad if it will not take a charge. It's time for you to buy a new battery.

On my laptop there is a small button near the hinge end that switches the display off when the top is closed. Make sure yours is coming up. It is something you can check easily.

The touch buttons are there so you can turn your laptop on into the Quickplay feature without having to load into Windows. So basically if you just want to use it for multimedia. If you was to press power button, these will just load straight into Windows. It is meant to do this. If you are saying that the screen doesnt come on when you turn the laptop on and are basically saying that the laptop doesnt boot at all and is just a blank screen, then it is very very likely you have a motherboard failure. Contact HP to see if they have still covered your laptop with warranty as this is a known issue on these laptops and some warranty had been extended

This sounds like *********** board is overheating due to probably dust and fan not working properly. Try using air can to blow some of the stuff of off the fan from the bottom of the laptop but make sure you dont tip the can over while doing this because the air turns in to ice and it will mess up you laptop. If just blowing air don't work then you have to open it and clean it up.Hope this helps.

1. remove all ext peripherals
2. remove battery
3. check first the ac adapter if it has led on (make sure ac adapter is not connected to the laptop)
4. try any other wall socket check if ac adapter will led stay on
5. if ac adapter stayed on then connect to laptop (without the batter)
6. after connecting the ac adapter to laptop check if the ac adapter led turned off, if yes then check ac adapter laptop pin on the side if is loose or damage.
7. if ac adapter stayed on after connecting to laptop press now the power button on the laptop just once. check if the power led on laptop will turn on (check if power led stays on or it blinks amber)
8. if it blinks amber then remove all CRUs such as dvd drive, memory, hard drive and wireless cards. put them back one at a time. make sure you turn off laptop when putting removed hardware. this will check and isolate which causing the power led to blink.
9. if the power led stays on then turn it off again then wait a couple of seconds then press and hold on Fn key then press power button. wait for about 5 minutes while the power led is steady on, until you hear beeps once you hear beeps it means that LCD has problems. try then connecting laptop to an external monitor if it shows display there. press on Fn + F8 to toggle the display from LCD laptop to the ext monitor. if no display replace the motherboard. if it has display replace LCD.

try it without the battery on the laptop. if it boots and stays on, put the battery back on and see what happens. If the problem persists, replace the battery. Acer will replace it free if you are still in warranty

try starting in safe mode (F8 when you turn it on)
see how long it stays on
try going into your Bios (del, or F1, or F2) and see how long it stays on

if you are in the bios and it turns itself off, you have a hardware problem (such as motherboard, processor...etc)

if your laptop is out of warranty,
Acer will first charge you USD 450.
It's look like your problem is fan, they may reduce to USD 200.
but if the problem is related with motherboard, the cost will stay USD 450.

if you still have warranty, just send it for repair, it should be free.

About your problem, it's look like the fan isnot moving, that cause your laptop overheating and then shut off.
and if you are comfortable, you can open it by your self and check if there is something that hold your fans.
