Cleaning the filter

Sometimes just blowing the dust out with a can of air is not enough. You need to remove the fan to get to the heat sink to remove the dust properly.

You could use a vacuum with a hose attachment as well to **** the dust out.

I don't think you can. If you take it to have a geek look at it, the first thing they will do is pull the RAM out, look at it to see if there is anything obviously wrong with it -- then re-seat it and try the machine again. So, you may as well at least do that. The RAM is behind one of the panels on the bottom of the computer. If there is two, pull both and try it with only one of them. This will start you on a process of elimination in case one is bad / one is good. But don't be disheartened yet if there is only one. It can loose adequate contact, and just pulling it and re-seating can fix.

Toshiba builds a good machine. But, they are bad about getting clogged up with dust. If you don't take them apart ever so often and clean the dust out, it can become completely clogged at the out-vent. This of course causes a barely adequate ventilation system to become not adequate. And your machine begins to overheat. And that can damage the motherboard or the processor. So, once a year or so, I take mine apart and clean it out. The last time I did this the out-vent was completely matted over in such a way that the dust appeared to be a filter of some sort. I was confused for a minute (even though I've done it before) and then, "Oh sh$#, there are NO FILTERS!!!" The first time I did this, there was actually a ball of dust that had been rolling around in the fan housing, like a snow ball, getting bigger and bigger. It finally jammed the fan, and that's when I knew there was a problem - because I had become used to hearing the fan (a lot). And that's another thing to mention; If you start noticing that it seems like the fan is real loud, like running real hard all the time...that's because it is. And that's because your computer runs a little program that tells the fan how hot the processor is.

I hope all this helps you. If yes, please take a sec to rate me. Thanks!

Glad you found the solution because I had never heard of the lcd locking.

If you install this freeware: Speedfan

It will read your laptop sensors and tell you where the heat is coming from ex: CPU core, Video card, HDD etc..

Try taking the twin filters outside - also take a dustpan brush and tap the filters gently on the bottom, then brush the dust away as it comes out. This can take quite some time, and you will find that LOTS of compacted dust will come out!

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.

Please check the filter. The filter is located behind the front grill. If there is a lot of dust & dirt on the filter, it will reduce the airflow over the coil significantly - causing freeze ups. A filter that is missing will require a thorough cleaning of the coils to remove the dust and dirt, then installing a replacement filter. There are products sold at hardware stores, home improvement centers, etc. designed specifically to clean these coils easily. You should be able to get a replacement filter for the AC from Sears.

If the filter is present and clean - there could be a problem with the refrigerant charge, or other problem. Many times, an AC units of this small size, it is cheaper to buy new than invest in repairing a 3 year old unit.

Please rate this reply if helpful - good luck!

i think your fan is not working
and dont kept on metal
