Laptop shuts off after 15 minutes, even when plugged into wall outlet. fan runs quieter than normal

F-8 is the key, Try to "cold start" the computer, meaning remove the power plug from wall outlet or uplug from computer, remove battery, now replace battery and plug computer into wall outlet. Push the on button while "TAPPING" the F-8 key repeatedly Tap, tap, tap, until you hear a beep or it load the black menu with safe mode options. IF THAT DOES NOT WORK: shut down the laptop,remove AC supply, remove battery. Plug the AC power back in,DO NOT INSTALL BATTERY, Start the machine, without battery installed, and tap F-8 repeatedly. If it still fails, PULL THE PLUG OUT OF THE WALL OUTLET WHILE THE COMPUTER IS STILL RUNNING. NOW PLUG THE LAPTOP BACK INTO THE WALL AND START, THAT SHOULD TAKE YOU TO A BLACK PAGE WITH WHITE SCRIPT WITH OPTIONS YOU ARE LOOKING FOR.

Here's a solution that often works. Turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and wait 12-15 minutes before plugging it back in. Then turn the Master ON/OFF Switch to ON and set your control as you normally do. Hopefully, that 12-15 minute timeout allowed the unit to reset itself. If it continues to do this contact Haier Customer Support 877-337-3639 and have your Model Number and Proof of Purchase handy. If it's less than a year old, it's still under warranty.

Good lick. I hope this helps solve your problem.

Looks like an overheating problem.

First, make sure that you put your laptop on some hard surface. If you put in on your bed for example, the soft surface will block the air vent on the bottom of the laptop, resulting in poor cooling of the inner components.

Do you hear the fan working, and air blown out of the exit vent on the side (or rear) of the laptop?

If not, then perhaps the fan is broken and needs replacement.

If the fan can be easily heard, working at full speed all the time, there is a problem with blocking the air inlet, or the internal radiator/heatsink got covered with dust and lint, and needs cleaning - try compressed air blown from the opposite direction (from the air outlet) to blow away the dust - of course with the computer switched off, otherwise you'll be "fighting" the fan trying to blow in opposite direction. If this doesn't help, the laptop needs servicing, as it probably lost the heat-conductive layer between the processor and heatsink.

Either relay will have to be replaced or the sensor. They usually run mabey 5 minutes top afterwards.

lets try this ---

* turn of your computer
* remove the plug from your computer.
* Remove the battery from your computer
* Let it sit for 3-5 minutes
* Replace the battery
* Plug your computer back in (Make sure the wall outlet is working as well, seems simple, but have seen it before)
* Let it sit for about 3-5 minutes
* Boot your computer
* go to
Start -> Control Panel -> Power Options -> Power Meter
Note the Total Battery Power Remaining

* Let your computer sit for 15-30 Minutes and see if the Total Battery Power Remaining has gone up.

If so problem solved

if not you may be time for a new battery.

Often, if a system turns off every time at roughly the same time, it's a hardware problem. System gets too hot, shuts down, restart it and it'll run again for a while, but not quite as long, and continue like that. Can you feel/hear the fan moving air? Possibly clogged, see what you can do to get it cleaned up a bit. Does it make any difference what surface it's on? May be covering a vent on the bottom or back.

You may have a short in the power connector on the mainboard. Try wiggling where the power cord plugs into the notebook and see if it cuts out.

A glitchy power supply could do it, especially if it's putting out too much power, or does it when it warms up a while. When the notebook cuts out, leave the power supply plugged in and test it with a voltmeter, it should match the rating on the power brick. A reputable electronics shop or computer shop could test it also. Get a recommendation; stay away from any chain stores.

Are you saying it shuts down even when you're plugged into the wall?

It probably shut off on high pressure. Let it cool down, plug your hole that you drilled and give it another try. The water is suppose to collect there and the fan is suppose to throw it into the condenser to keep it cooler and make it run more efficiently. Good Luck,
