When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith 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 surethe vents are clear and dust free. Use a can of compressed air to do this.

Water damaged Laptop


Attaching an external keyboard does not help because the keyboard controller is damaged.
I recommend you put your money towards a new laptop as the cost of repair maybe too expensive or beyond repair. Most computer repair shop charge for a quote and may drop this charge if you go ahead with the repair.
If the hard disk is OK then I suggest you remove it from the laptop and insert it into an USB hard drive adapter case and use it as an external USB hard drive for backups and data transfer etc.

You need to replace the battery as it has expired.
They are available by typing the battery model number or laptop model number into ebay or Google or indeed any search engine.
Hope that helps.

Computer shuts down immediately after I turn it on.


First look for the obvious-make sure it's plugged in to a power source and make sure you got enough battery power. Nothing?

It immediately shuts down, because it's telling you it needs to be taken in to have the Apple dorks fix it, as this is not something that can easily be fixed on a web site. Opening this thing up with hands on fixing is required for your machine, but keep in mind that your warranty is void if you spilled water on the laptop.

My laptop turned off but it has 35% remaining battery


Laptop turns off suddenly? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage.

If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed.

Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot.

The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down.

Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

My laptop turn off, I think it got hot, I can't turn it on now. turn off Sunday


Hi
try this,
unplug dc plug from laptop. remove battery.
wait a few minutes. press and hold the power button for 10-15 seconds.
plug the dc power plug back into the laptop, but do not put battery back in yet. Then try to power on. if it powers on, let it run a few minutes, but best to keep checking to see if it is getting warm or hot anywhere. if it is getting hot shut it down immediately. If it isnt getting hot then shut it down and put the battery back in.

if it doesnt power up, then i would have to suspect heat damage to the motherboard.
