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.

As well as cooling fan issues they’re can be power faults. Its best if you open it up and check that nothing is damaged – Mine was doing it and all the motherboard had cracked somehow (WARNING: PLEASE FOR THE LOVE OF JESUS DON’T OPEN IT IF YOU DON’T KNOW WHAT YOUR DOING. I WILL NOT BE HELD RESPONSIBLE) also had connection problems on the solder. Just check it out.

Toshiba M35X-s3112 screen went blank and appears to be in hibernate. I removed battery, ac adapter, tried all the ‘tricks’ published on various sites.
Turning on power bios used to access dvd, now nothing. Screen is completely blank. Changed memory removed memory, no error codes via sound. fan comes on as it should when starting then it turns off as usual as the laptop is not hot. I have disassembled. not much dust inside machine at all. have connected to monitor still nothing. Does not appear to be hibernate switch. I had been using the laptop and was clicking on an icon when the screen went black.

My laptop turns off seemingly randomly but 95% of the time it turns itself back on again. Most of the time, it won’t make it all the way through a boot before it turns off again and on.
Here is what i have tried but has not solved the problem
1. As mentioned above, i opened up my laptop to clean out all the dust.
2. Wiped my HDD, set to factory condition, formatted and reinstalled O/S from Manufacturer.
3. Wiped my HDD with Manufacturer provided program and reinstalled O/S.
4. Ran computer with power adapter plugged in until battery at 100% then unplugged. Worked for a few weeks. Then it didn’t.
5. Charged battery to full with computer off, unplugged and turned on.
6. Charged battery to full with computer off, kept plugged in and turn on.
7. Removed battery and plugged in adapter.
Just when i thought i’d figured out that it was the power adapter, my laptop turns off without the adapter plugged in.
8. Ran computer and played game. Power adapter plugged in. Accidentally hit alt tab and returned to windows. Too slow to return to game. Turned off and on. Repeated, intentionally hitting alt tab, waited and turned off but not on occasionally.
I was going to try my spare battery but I’ve misplaced it so i’d like to exhaust all my options before i go out and purchase a $140 battery, or a $60 laptop power adapter.
I’m starting to think i have a short somewhere or didn’t clean well enough.
My technical trouble shooting skills are average.
Can someone please help me?

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…
