Laptop Tips: Overheating Problems

Overheating Frequent overheating will damage the motherboard!..becomes unstable, no display, hang-up and worst black-out or no power at all.
Symptoms: The laptop starts beeping, freezes, restarts by itself or shuts down after it has been on for some time, typically 10-15 minutes or more. If you start it again, it does the same thing after just a few minutes.
Troubleshooting: Most laptops overheat because the fan intake is blocked either from placing the laptop on a soft surface or by dust. In either case you will need to let it cool down before turning it back on (may take up to 30 min). If you suspect that dust is blocking the fan/heat-sink, get a compressed air can and try to clean it now (that will cool down the laptop too).
Sometimes overheating is caused by a fan malfunction. If the fan is completely stuck, the laptop will show an error message immediately after starting. However in rare cases the fan’s fins are just loose or broken and won’t move enough air to cool the laptop.
In either case you should try cleaning the fan(s) and heat-sink(s) with compressed air. That is best done outside, as usually there is a surprising amount of dust accumulated in there. If the laptop continues to overheat, you will need to bring it to a repair shop.
Also if you have dropped the laptop, the screws holding the heat-sink may have broken off. In this case the laptop will overheat in just a couple of minutes as the CPU has lost contact with the heat-sink and is not cooled at all.

Another one is moist inside the motherboard or corrosion.

If this troubles may arise and can't solve it yourself, bring it to certified laptop repair shop.

This is the point where you need to determine whether or not the laptop has sustained permanent damage due to the overheating. Most laptop manufacturers have a safety cutoff that is triggered when the device becomes too hot and this feature will usually prevent permanent damage.

To determine if it is damaged you can:
Remove the battery from the laptop, and simply let it sit for a couple of minutes. Let it cool down, then reinsert the battery and attempt to reboot the machine. If it powers on, there is minimal or no damage. Best case scenario, your device will be fully functional.

If the device still does not power on:
Your options are to take bring the computer to a store that will run a diagnosis for you and determine to what extent the laptop has been damaged or you may accept defeat and start shopping for a replacement (worst case scenario).

I hope my answer has been helpful.

My computer hang up and restart what should i do?

1. Check the temperature inside the CPU.
Overheating stops the performance of your Motherboard.
Add more fan to help cool down the CPU.
2. If you have digital tester in you... check if the output supply of the power connector is exact 5v and 12v.
If its below, then the supply is unstable, you will need to replace your power supply.
3. If you have back up video card and memory card try to replace the one you are using..one at a time and monitor the performance. To find out if hard ware cause your system to restart.

Random restart

This definitely sounds like the CPU is overheating, graphics card is overheating, or your memory is failing.

Check your CPU temp. and fan, and check graphics card fan.
