Question about PC Laptops

I have an Avent 5431 laptop and i figured out that if you press Fn+F2 it turns the speed of the fan down which then eventually causes it to overheat. How do i turn it back up to normal speed again?

    as that is a support forum for avent you might want to post that type of question there as i can't find the manual... look at the keys tho... do you see any that have a icon of a tiny fan... if so experiment with the function key. incidentally alot of those laptops get close to meltdown anyways.

My laptop keeps turning off


OverheatingWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the 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 with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

How do you turn on wifi for dell latitude d610


There is not wireless switch on this model. To turn on your wireless you will need to hold down FN + F2. If this does not turn on your wireless its most probably disabled in the Bios. To enable it, press the F2 key at the Dell Logo on startup, move down to wireless, press enter and move to wireless control, make sure its set to Fn+F2/App, then move down to wireless devices and make sure it set to on. Press Esc, and save changes and exit.

Fn+f2


fn+f2 means your pressing two keys at once
the function key (fn - usually a different color - maybe blue - than the letter keys) and the f2 key

hold down the fn first then the f2 - look for the fn on the lower right or left next to Ctrl keys
