This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

Is there a quieter fan for the sony pcg-k45?


If your fan is very loud, and works all the time, then probably you'll need to clean up your laptop from the inside. On average it only takes 3 months for any laptop to gather enough dirt so the CPU heatsing gets totally clogged and this causes the fan to work all the time, and in extreme cases your laptop even turns off so it protects the CPU from the excess heat.
Here's a very good overheating laptop cleanup tutorial with some best practices that any laptop owner should know.

I dropped my Sony PCG-3E2L and now the fan is not running. Lap top shouts off after a few min


If the fan is not running you should use the computer because you could cause it to overheat and become very damaged. Right now it is possible that JUST the fan is broken, which would be a simple fix. The reason the computer is shutting off after a few minutes is because it's trying to save itself from melting. You need to remove the fan, find the manufacturer and model number on the fan and order a replcement and install it before you attempt to use the computer any further.

I hope this helps! If not, please comment back and let us know!

Fan is running hot and it makes one side of the computer very hot..laptop computer


That seems to be typical of that model. Oftentimes, it's the battery, microprocessor(s), or a combination of both. There are devices to cool the computer off, or you can use a small fan, that helps. Make sure it's not dirty inside (consult your manual on cleaning, or tech threads on this site). I wouldn't be alarmed, it seems to be typical with this model.

Put the cd in and restart. If it doesn't give you a message to press "x" to boot from cd, then you need to chage the boot order in the BIOS.

To get into the BIOS, restart and press del or F2 (it might say something on the screen like press del to enter setup) that is the BIOS.

Change the boot order to CD first.
