Hi Julie, the dual fan cooling system generally works with the larger fan being the radiator cooling fan and the smaller fan being the A/C cooling fan! If you start the vehicle and turn on the A/C and select the coldest setting within a few seconds both fans should start working!
Power adapters fail because of power spikes. You can do a preliminary test of your system's adapter by plugging it into your notebook and checking to see if the computer indicates that its battery is charging. Usually there's an LED (light-emitting diode) that flashes when the battery is charging. If you can't test the power supply using this method, take your notebook computer to a technician who can test the adapter.
I would take the laptop back to the store I bought it from and ask for an exchange. Changing a fan on a laptop can be a very intense process involving removing the entire motherboard. This could also be a bios setting issue but to seek advice from someone who hasn't touched the laptop for a fan issue is not a good idea. Heat is a laptops worst enemy and the only things fighting that enemy are your fans.
It sounds like your cooling fan has stopped and you bought a new one. The fans are plugged into the motherboard. Your motherboard probably has at least two fan connectors-they are marked "fan" or "case fan" or something like that. There is no button to turn them on. They come on when you start the system.
Solution 1) Set the system cooling policy to "active"
Windows has two approaches to fan control - "active" or "passive". The default option is passive, but if you switch it to active instead then the fan will turn on more frequently. You can do this by following these steps:
Left click the battery icon in the bottom-right corner of the screen (See image)
Change Passive to Active for both Plugged in and On battery(See image)
Do the same for any other modes you use, such as power saving mode
Restart the computer
Solution 2) Keep Toshiba PC Health Monitor open
Some of the comments below sing the praises of PC Health Monitor. Apparently, the laptop fan will work harder when PC Health Monitor is open.
PC Health Monitor is already preinstalled on Toshiba computers. To open the program, just press the Windows key to open the Start menu, start typing "PC Health Monitor", and the program should appear in the search results. Click on it to open it.
"Turn off computer and unplug power cord. <br>Disconnect all
external devices. <br>Remove the battery. <br>Press power button
and hold for 10 to 15 seconds. <br>Plug power cord back into computer and
press power button. <br>Check front panel LEDs (lights) on bezel (front
face) or optical drives and listen for power supply fan. <br>If LEDs are
on or power supply fan starts spinning, watch for boot screen on monitor.
<br>If computer begins to start, turn it off. <br>Reconnect any
external devices. <br>Press the power button and make sure the computer
starts. Please save this steps and go through that. If in case you require
further help, you need to contact Answers by Gateway department which is a paid
support. The phone number for Answers by Gateway is 1.800-237-6483. Or please
consider contact with a local technician for a detailed troubleshooting."
worked for mee!! good luck
Are you sure that nothing is overheating? If your cpu fan is turning too slow it won't disipate the heat. Do you have a program showing cpu temp:? I would take the access off the bottom and make sure the cpu fan is clean. If that is not the problem I believe you can turn the warnings off in the bios settings
That can be normal. Normally cpu fans start up only when cpu reach a determined temperature. After it cools down it stops until temperature reaches starting point again. Generally, when the fan is not working properly, the computer turns itself off after a while because of overheating. If you have this problem, laptop turning itself off because of overheating (check it is not hibernating etc.), then you usually solve it by replacing the laptop cooling fan. Generally, 'fan on laptop intermittent' is not a symptom of malfunction.
