cooling fan

Toshiba Satellite a135
February 18, 2009 at 21:41:15
Specs: Windows Vista, intel celeron/2Gb
I upgraded my ram to 2GB a few weeks ago and my cooling fan quit working. I took it apart and the heat sink was plugged so I cleaned it. The cooling fan would barely run afterwards, so I replaced it. The new fan does the same thing.

Any thoughts or ideas?

Assuming this is a laptop? assuming this is the CPU cooler fan? Do you also have a laptop case fan? How do you know it (fan) quit working? Did it not work at all? Was it noisy? Did the system overheat? Does it seems like the fan bearings are dragging? Fans on laptops will only work when they need to - when the system gets warm. Otherwise, I've seen sensors go bad (they're ON the MB though). Look for Toshiba diagnostics where you could maybe test the MB and/or the fan(s).

Sorry, yes this is a Toshiba Satellite A135 laptop. It has a cooling fan which has a Heatsink that runs from the top of the CPU to in front of the cooling fan. I didn't mention this; When I upgraded my Ram and turned the laptop back on, it powered up and I got to the desktop then it powered down and shut off by itself. I turned it back on and that's when the cooling fan became an issue. I did'nt apply any new thermal grease after I removed the heatsink and cleaned it but I,m not sure that's the issue. I downloaded a fan monitoring program last night and it says the core temp bounces between 45 and 50 degrees.

Cardinal sin ~ thermal grease. ALWAYS need to reapply that!

Other things to note, make sure the RAM is:

1. Compatible (sometimes even if the RAM says its a particular type & speed, they don't always work, depending on the MB).

2. Good (you can test it with Windows memory diagnostic): http://oca.microsoft.com/en/windiag...

Applied thermal grease, no luck. Upgraded drivers and bios also. Bad Motherboard?

Got the old ram? Did you test that in there?

Pull and reseat the ram, cpu, clean (compressed air) the ram slots?

Did you find a Toshiba MB diagnostics tool/or maybe a general one?

Could be a bad fan sensor, I have seen that before on Dell MB's.

Laptops suck, they're one of the biggest technology rip offs out there.
