Toshiba A215-S5837. Fan keeps coming on constantly. Just about every 10-15 seconds then shuts off after about 5 sec. The CPU is only running at about 10% and 43c. Is there a way to control this fan? The computer is only two days old so I know that the CPU and Fan are not dirty. I have tried messing with the power option settings in Vista to stop it from coming on so often but that doesn't seem to work.

When the CPU in the computer or laptopoverheats then it will shut down (i.e. thermal overload) and won't boot upagain until it has cooled down. If this is the problem is not fixed then theCPU will eventually fail. A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.
Try to fix the problem without taking the laptop apart first but I would recommend using a powerful air compressor instead of a vacuum cleaner.
Welcome to FixYa! Based on the error you have received, this means that the cooling fan of your laptop needs to be cleaned and checked at. This is a common problem with any toshiba laptop. I suggest checking the heatsink of your laptop. If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It's nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
Clean the fan and the heatsink with compressed air.
The bearing in the fan have most probably been worn to the extent that the fan needs to be replaced. The best way to reach it is to out the screws pertaining to the CPU cooler at the bottom of the laptop, it may be complicated and I advise you to take it to a technician. But before this you could always give the fan a good vacuum out if you can reach it from the outside. It may just be a bit clogged with dust.

A common problem with all laptop is dust. Sounds like you have 5 years worth of dust stuck in there. You should get a can of compressed air and blow though every vent you can! You want to loosen the dust that's in there and possibly try to blow it out and/or get it closest to the vents.
After that you should take a vaacum cleaner and **** out all the dust you can!
Dust inhibits air flow, alot! Its the number 1 killer of old computers.
Hi, You have to find out where the noise is coming from. It could be; 1) a fan on your motherboard if it has one 2) the fan on your heatsink that keeps your cpu cool 3) the fan on your power supply unit 4) a cd or dvd rom drive 5) one of your hard drives 6) one or more of your case fans. 7) a fan on your video card if you have one.
You don't want to open your power supply, so if this is the cause of the noise you can replace the whole PSU. Other than that, any other component listed above can be replaced by going to newegg.com for parts.
might have to get a higher wattage power supply,
the initial amperage draw plus everything else may be causing the stock power supply volts to dip past the limit
maybe download the intel active monitor and study that, or hook up a voltmeter and watch the output at startup.
If you DO NOT hear the fan running, have it looked at by a professional. Your fan may have died. If you can hear the fan running, blow out the fan exhaust port in the opposite direction of normal air flow. Especially on lap tops, the heat sink cooling fins become completely clogged with dust. When this happens the processor overheats causing it to run slow and eventually shuts itself down to keep from going super nova. You should blow it out at least once or twice a year. Also, if you use your laptop on the couch or in bed, place it on a hard surface like a cutting board or something similar that will allow air to flow underneath the computer. This will also help prevent dust from the cushions or blankets and such from clogging the cooling fins on the heat sink faster than usual. Remember blow it out in the opposite direction of normal air flow. You want to blow the dust out the same passage it came in through.
Sounds like either the PSU or a part (CPU) on the motherboard overheated and fried. How do you know that the PSU is good? Did you take it out and try it in another computer? If not I would try a new power supply first.
