    Check your fan settings in the control panel, power settings group. You might have set to silent mode.

    Your fan only comes on as needed. If you are using a laptop cooling pad that may account for the on/off behavior.

    When you boot up you can enter the Bios Setup screens, DEL or F2 I believe. In those pages is a page for your hardware temps and a monitor of your fan speed. Leave your laptop on and that screen on display and monitor your Motherboard temp and CPU temp and Fan speed. You'll also may see board voltages and see if those change much .

    Your laptop has an alarm if the CPU gets too hot. It often sounds like a stuck key signal, continuous beeps and then the machine would shut itself down or should if the CPU reaches a critical temperature.

    The fan is connected to the motherboard to receive its power. You could nudge the connectorr gently and see if this affects the fan working or not. You could also blow the fan out with a can of air. Don't handle the can upside down or in a radical angle so you don't spray propellant onto the CPU. That could cause damage.

    Also, while its off, check to see if the fan moves easily or has a bit of trouble getting started. Most fans' bearings or sleeve bearing are not sealed but may have a rubber cap that comes off rather easily. Often we have to remove the manufacturers sticker to access this bearing location. A drop of machine oil, sewing machine or 3-1 will often be enough to lubricate a fan so it spins more easily. You may even have to remove the fan, turn it over and then access the bearing cap and oil it from there and then return the fan to the CPU mount.

2010 Lincoln MKS Heated Seat on driver's side stopped working (Light in button turns off on its' own)


The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

My hyward H400ID won't ignite green light comes on for few seconds and then goes off. Need help


There are many questions needing answered. Is the fan coming on, if not it could be the fan proving switch. If the fan is coming on but the heater does not light there should be a code on the heater. I added a link to the manual for this heater. http://www.hayward-pool.com/pdf/manuals/H-seriesLowNOx-H250IDL2-H350IDL2-H400IDL2.pdf

A/C fan cuts out completely when on high fan AND recirculate


Replay the blower resistor. Used to be you could replace the relay, but they are built into the resistor now. Should be under the passenger side dash. Usually behind the blower. There will be four to six small wires going to it and two big wires coming from it going to the blower motor.

Cooling fans on radiator will not come on. what can i do?


Hi kattrinahawk, If your cooling fans do not work, take a second to understand the system: 1)Fans will cycle on and off depending on engine temperature. 2)Fans will come on when Air Conditioning system is On. 3)Fans will come on if certain malfunctions in engine electrical systems. Fans are controlled via the ECM/PCM or sub computer. Fans usually have separate fuses and or relays/resistors. Ok so lets check a few things: 1)Check your engine coolant level, fan operation is depending on correct/full level 2)Turn your A/c on max settings and wait a few seconds see if fans cycle. 3)Check for obstructions or loose wiring around/on fans. 4)Inspect fuses per owners manual locations identification.

I have a Toshiba NB200 notebook which has suddenly decided not to boot up. The only light that comes on is the power light and just the fan comes on for a few seconds and then stops. Any advice please.


Could be a few things but sounds like the RAM is faulty, replace it and it may boot. If not remove the hard drive and then reinsert and try to boot and if none of these two work then it may be the motherboard in which case you have an expensive paper weight!

Booting


Has the fan been replaced? If not then the laptop will power itself off to protect from overheating. The fan is like a switch in the loop. Like old Xmas lights. One not working then none will work.

Ge after replace fan still fan not working


Something to check for. Is the top of the refrigerator door lower than the freezer door? If so the ref. light may not be turning off all the time. Pull bottom panel off to expose hinges. The ref hinge should have an adjuster. Adjust door up to be level with freezer.
