Hello Guys,

First of all sorry about my English (not my mother tongue).

I have a laptop (Lenovo ThinkPad Edge) that cause me a problems in the past 24hr.

He is shutdown himself after 10-15 min, with or without (at all!) programs running in the background.

I've notice that the fans is working always, from the stratup to the. The "wind" that coming out from there is not warm like he was

in running of big applications such as HD movies, Games.

Big THANKS in advance! :)

Try to start it in bios and leave it there, does it get warm and shutdown then to ? Then try to boot it into a linux memory stick, does it get warm and **** down then to.

if the if both are no, there's something wrong with your windows, possibly malware. if the answer to both are yes, you have a hardware issue.

lol, It's a he? Why not a she?! xD but yeah.

A lot of languages assigns words sex, he, she, it. in english everything is generally it.

Looks like overheating. Use a program like SpeedFan or OpenHardwareMonitor to check the internal temperatures, especially the CPU. Overheating could be caused by dust accumulation as others have pointed out.

even when overheating, it should be generating enough heat to feel like he's gaming as soon as he turns it on. which indicates a bigger problem than dust, but the CPU being over stressed from the get go.

remove bezel, remove keyboard, remove everything else using an ifixit teardown guide until you get to the heatsink assembly. using a q-tip remove all the dust thats blocking the airflow channels.

Saying no warm air is coming out is saying no warm air can get out. You do not feel any air correct? or you only feel cold air? Laptops are thermostatically controlled, if the CPU is not warm the fan will not work. When CPU hits temperature set in bios, it will enable fan until it hits lowest range of temperature, and will shut off fan to save power until CPU gets hot again.

You may also be able to get to fan/heatsink assembly an easier way - but usually its tedious. don't break any ribbon cables or their delicate connectors. use a small jewelers #0 straight screwdriver to flip them up gently. Take many photos if the guide isn't good so you can reassemble.

Aside from that it would have to be bad temperature sensor or malicious bug/virus. Leaving it in bios screen on the temperature page should reveal what its doing without needing software or worrying about a windows-based reboot. If temperatures are not rising, maybe do 'restore bios defaults'.

would write down all your current settings, restore defaults/clear CMOS, then re-enter them. I have seen corrupt CMOS settings do weird things.

Feel free to question if something is unclear to you and I will try my best to explain it. Good luck!

Now i restored the default BIOS settings, after that i restored my windows to the last restore point.. The message that i got in the beginning from the tray icon area is:

"PCI Standard Host CPU Bridge Drive is updated".. something like this, and i remember that the fan problems started after i got this message this morning.

Have you resolved your issue? Further I suggest making sure device manager has correct hardware ID on everything (no triangles or unknown devices)

After that, go to computer makers site or Motherboard manufacturer and download chipset drivers. Generally if they updated it was done wrong and you need specific ones reinstalled/restored.
