My laptop turns off without any reason
After I turn on my laptop it works fine for 25-30 minutes and after that just turns itself off without any warning. When I turn it on again, it works for some time and then shuts down again. What is going on? How can I fix it?
Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan. The notebook processor produces a lot of heat when the notebook is turned on. The cooling module helps to keep the CPU cool when the laptop is working. The cooling module includes two parts: the heat sink and the cooling fan. The heat sink is attached to the CPU and helps to conduct the heat from the processor to the radiator. The cooling fan blows on the radiator and helps to disperse the heat produced by the CPU. The laptop will overheat if the heat sink radiator is clogged with lint and dust or if the cooling fan stopped spinning.
If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged. In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning.

I have a macbook and am really frusturated when I close it because it goes into sleep mode but when I hit the key pad and even the keys nothing happens.
I have to re-start it and THEN it tells me I didn’t shut it down right – well no kidding if I couldn’t get it to come out of sleep.
Anyone have this trouble?

My Lenovo Thinkpad T400 turns off when I close the lid. I double-checked the settings and it is set to sleep on close. When I restart it it says that it was not shut down properly. I checked and this happens if i just shut the lid and open it again right away.
I am running Vista Home Premium.
Thanks

Nick,
Can you see the cooling fan working? Maybe the fan is bad and the laptop shuts down because of overheating.

Hello Laptop Freak,
I have Advent 7104 laptop. It starts OK, runs OK, after about 10 mins it locks up for about 1 sec then it shuts off. I turn it back on it then last for about 2 mins and turns off again
I have completly stripped the laptop, cleaned the fan & heatsink, still the same, I have even amended the registry to see if there is a report in the event log, but nothing shows.
Any ideas?
Cheers,
Nick

Aamir,
Buy a can of compressed air or even better find an air compressor and spay air inside the fan grill on the bottom of the laptop. This will remove mode dust from the fan and heat sink.

Aamir,
Buy a can of compressed air and spray it into the air intake on the bottom of the laptop until all dust is gone. After that spray air into the fan grill on the side.

my lap top switches OFF whenever I ask to do something too complicated. for example, I watch a video and do not like it so I stop it and click on another one, ater a few seconds power goes OFF.
I and whenever I switch ON again, the laptop may reboot totally or it may not.. best to leave it for several hours then start again… but take it easy. last time it caused problem was due to pics in the email not as attachment then when I finally was able to get laptop working again, tried to delete that email , laptop switched OFF ,
only cure I have found so fat is to re-install everything from the start……..but …. it happens again when the “load” get to be too much for it…
