My laptop is a gateway md2614u and fan turns on for like 5seconds then turns it self off and doesn't come back on and then after like 30seconds my laptop shuts off if I don't have it over a fan or vent. If I have it over a fan like 10mins if a vent it doesn't shut off till vent turns off. I have replaced the thermal paste and it still does it. Almost like the fan not reading that its hot. also started after I ran virus, malware, optimistic scan. So maybe it changed or deleted something? but i have been using them for years. also I clean my laptop so that not a problem. and there is no fan settings in BIOS.

Hello wantedtrenton,

Welcome to the WTT Forums. ^_^

Unfortunately I think you might have to pop down to your local PC Repair shop and get the fan replaced, or replace it yourself. Continuing to run the laptop may present a significant fire risk. The laptop is obviously shutting itself down when it's getting too hot, trying to push it further may be unwise.

Saying that, if you still encounter the same issues after replacing the fan, it might be down to your power settings. Have a look at the 'advanced power settings' and then go to 'Processor power management' and have a look under 'System cooling policy'. Make sure it's set to Active and not Passive. The latter stops the fans from running, or at least dials them down.


Cheers,

Umm I kinda figure that. and there is no "Have a look at the 'advanced power settings' and then go to 'Processor power management' and have a look under 'System cooling policy'. Make sure it's set to Active and not Passive." unless i looked at wrong spot ill relook after the reformat goes threw. which i would think fix that problem if it is that.

Did you try a new fan? You have a fan can not some serious damage to your laptop. I would have to say your can gone repair shop and then your laptop fan working.

or maybe its not properly connected to the power supply. more over, you can check the bios like stated above and check for power distribution.

From your next post.

Almost like the fan not reading that its hot

Fans do not have a temp. reading capacity, only motherboards do.

This might be a motherboard problem with your fan controller.
Your fan controller on your motherboard may be on the blink.. All that connects your fan to your board is a 3-pin connection (sometimes even two).

You need to replace your fan and if it is still not working correctly your next culprit would be the fan connection or motherboard, as generally an electrical component running for 30 seconds then shutting down points to capacitor failure. Check your capacitors. Do they look normal as in no mushroom look effects or leakage?

Another possibility is a poor power plan. The power plan settings as mentioned by Nahumi are the first thing I would check. Power Schemes for Laptops vary but try this: Go to Start / Control panel / power options / select a power plan / select "Balanced".

See how you go, but if you think a HDD reformat is going to fix the problem, well miracles do happen, but not often with computers. :lol:

Cheers,
Lee

There is a program called SpeedFan that will allow you to conrol the fan speed yourself.

Here is the link to the site:
SpeedFan

This is a powerful program that will allow you to change many basic system settings and I would not recommend changing any of the default settings other than the check mark to turn on the automatic fan speed.

As far as I know this will not start when the computer does so you will have to run it after every start. As such, this is not likely to fix your problem, it is more of a band-aid until you can get it fixed.

Hope this helps :D
