[RESOLVED] Lenovo Y450 Ovheating!

post #1 of 10
Thread Starter 
hi I'm new here and I experience similar problems with hikarushirou, my computer overheats to games, eg. minecraft, it reaches high temps of 108
I tried to cope with it with a little success by switching to power saver mode (you should try it)

I lost the original charger for my laptop, and replaced it (apparently with a different model but same specs as the original otherwise)
I suspect the problem might lie in the ac adapter, as when I use my friend's one (he owns the same laptop as me), temperature of my CPU and GPU dropped tremendously

please help! thanks!

im sorry for the bad english here

-I've reapplied my former "foam-like" thermal paste... it works (:


-update I think it is the problem with the thermal paste... I found a ultra-thick, dirty and gum-like thermal paste, and removed it completely... my father did that to the desktop before and it worked, but im getting a replacement thermal paste soon

Okay, i think i can help.

Useing power saveing mode to help with temps is a round-about solution. You are lowering your overall performance to lower temps.

The factory thermal paste should never need replaced unless you have to replaced the processor or heatsink (or if you computer is really really really old). If you put a new layer of thermal paste on and it is too thick, your temps will be even hotter. Old thermal paste is very rarely a problem. I really doubt this is causeing your temps.

Your AC adapter has nothing to do with your temps. It is impossible for you AC adapter to made you CPU or GPU temps drop.

Here are some better ideas.
1.) Use air duster like this to clean the dust out of your laptop.
2.) Use a cooler like this to keep your laptop cool.
3.) Always run your laptop on a hard surface like a desk or a table. NEVER leave you laptop running on a bed, couch, or carpeting. This is because the fabric clogs the fans.

You english is pretty good. If anything i said needs more explination tell me.

If your CPU is 108 C, that very bad. If you overheated your laptop too many times, it could be damaged. Once your laptop is damaged by overheating, it will never run cool again.

what type of surface do you have the laptop on? Make sure that air can get into the intakes and out the exhaust. If the laptop is a couple years old, you may even venture to do a complete tear down and remove any dust, ect from the heatsinks. I had a friends laptop that was over heating and he was using compressed air, however there was so much animal dander clogging the heat sinks that it didn't matter. I cleaned it out and his cpu temps dropped by 15-20c.

quick question, is the 108 after you removed the thermal paste? I hope that you haven't tried to use it after removing the old thermal paste.

Sorry for the late response mate. Do you have the new thermal paste yet? Also, please post pics of the components the next time you open the laptop ( and if we could see under the heatsink (i.e. the processors), even better. We have to be sure we're on the same lines here. If the thick stuff you rubbed off was thermal paste, then it will explain the high temps you're getting after removing it.
Summary: We need new thermal paste. Fast. :-D

keep us posted. And I do apologize for my late responses.

What are the specs of the AC adapter, and what does your laptop require?

Depending upon the manufacturer it might, Apple for one is horrid in their TIM applications, and too much till cause the TIM to act as an insulator.

What? that isn't how it works. Overheat it too much and it will malfunction (causing instability) or straight up die.

No. Typically it just striaght up dies. I have had a partial hardware failure, where it stopeed running cooly and was consistantly unstable (because of thermal damage). My heatsink was just fine, my drivers and fan worked just fine. It just stoped running cool after i damaged it.

(The card that was damaged was a 7600GT, and it was a year after the 8 series was out. So i upgraded to a shiney 8800GT)
