When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Laptop power light comes on , fan starts then laptop shuts off


Laptops (and PCs) have sensors to kill the power when overheating takes place, particularly the CPU. You should take it to a local repair shop and let them look at it for you

Try removing the laptop from the doc, pulling out the battery, hold the power button down for 10-20 seconds, and re-install the battery.

This should drain out the laptop and it should boot up properly without the dock.

I press the power off button and it doesn't power off


You should never power down by pressing the power button unless your system is deadlocked and won't respond to any other actions. Powering off in this fashion can cause you to lose data, corrupt files, and improperly shut down Windows.

Nonetheless, if you are in need of shutting down the laptop in this fashion you must hold the power button instead of only pressing it. You'll find this in the power settings of the device. Honestly, the power button may even be set to do nothing, which is possible.

To properly shut down your new Pavilion laptop, which should be running Windows 7, follow this process: Click Start > Shut Down

Start is now simply a circular Windows icon in the bottom left corner of the screen and shut down has an arrow pointing down next to it. Click the words shut down instead of the arrow which will bring up other power save options.

Acer one notebook no display and automatic shutdown


= if your laptop computer will not start =
laptops have power supplys that can lock up
the power adapters conectors break all the time 
and the batterys are designed to be "con$umable$" 
so 

- - -- - -- - -power reset - - -- - -- - -- - -
remove the power adapter's wall plug & 
leave the power adapter plugged into the computer 
but pull the laptop battery out of the laptop.
press the power button just like you are trying to start it 
but press it longer, this will drain & reset 
the internal supply, now relese the button.

-- - -- - -power adapter only test - - -- - -- - - 
reconnect the power adapter's wall plug 
press the power button to start it with just the power adapter , 
If the power adapter starts the laptop on its own go down to  
"If the computer can be started"

If the power adapter does not start the laptop on its own 
leave the power adapter plugged into the computer but 
remove the power adapter's wall plug & press the power button 
just like you are trying to start it again, 
then relese the button 

- - -- - - battery only test - - -- - -- - - 
unplug the power adapter & put the battery back in  
press the power button to start it with just the battery

if the battery starts it on its own go down to 
"If the computer can be started"

if the battery ALMOST starts it on its own 
DO NOT BUY A NEW ONE! it may only be discharged 
locate another laptop just like yours and charge it, 
and yes this is crazy and yes i am sorry!.

- - - - - - - - - - - - - - - - - - - - - - -
- if your laptop computer cannot start at all - 
- - - - - - - - - - - - - - - - - - - - - - -

this can be caused by a bad; 
connector ($5-$60), power adapter($5-$60), 
battery ($70), internal supply ($40-$90), 
or main/mother board ($100-$300)

If the internal power supply is bad or if the 
power conector fails at random (intermitant) 
most of the cost is determined by how dificult 
finding parts and dismantling the laptop is 
and if it's external or internal

Laptop keeps losing power at start up and shuts down repeatedly


does it run with the power cord plugged in? if so your batterys dead, otherwise harddrive/bios/motherboard fault? is your power supply charging the battery?

I re-started my toshiba A135 laptop, and the screen went black


There are dozens of possible root causes for your problem I guess.

But exactly the same happened to me in fact on a packard bell laptop. After my son forced it to reset, it didn't start again. Only one led was lit. After a long search I found that the battery had died and this prevented the laptop to start even when the power supply was plugged in.

Try this: remove the battery, connect it to the power supply and restart.

Hope that helps

Shutting down


what is happening is it is hibernating not shutting down, open up acer empowering technology and go to the power settings or click on the battery icon in taskbar and click power options, then there will be instructions that say when i turn off; power off and not hibernate as probably selected.
