My hp dv7 3057nr has had this problem for a while.
As soon as I switch my computer from power saver to high performance it overheats and shuts down.
On startup I get the slandered overheat message, but often times it will shut down again while booting up even after leaving it off all night.
Now this is when it starts to really get freaky.
I performed the following test.
1.I turned my laptop off
2.placed it in a large air sealed freezer bag
3.placed said bag in my industrial freezer
4.let it chill for 3 hours
Now I took it out and booted it up. It overheated 30 seconds after I logged in.
Did I mention it was still in the freezer? Out of the bag even.
What the hell? It was so cold!
Why does my laptop overheat in high performance mode even when its IMPOSSIBLE for it to even be room temperature?
I mean... Jesus Christ
I just downgraded my bios to test if it fixes it. Wish me luck.
