Hey All, I have a HP Pavilion zv5000 Laptop here and upon receiving it I was told it just shuts off when trying to boot it up.

I have been playing with it and it does just that...it gets to the windows splash screen and then once it leaves there (and now if it even gets there) it just shuts off.

I have done a memory test and HD test (short test as it won't staying running but 2 minutes at most) and both results were fine. I have tried to use an XP cd to do some stuff and it still just shuts off.

I am thinking it is something heat related as the longer i play with it...the amount of time it stays on is shorter. Its been off all night now and I tried to start it this morning and it was on for maybe a minute and just shuts off. I am on the verge of just taking it to an HP dealer and letting them diagnose it.
Any Ideas?? :shrug:
 
Taking it in for service would be your best option, since it should be under warranty. There should be a side or top vent for heat. This should have a airflow due to the cooling fan. If not or it is very low, then the cooling fan for the processor may be defective. In addition to heat, there may be voltage regulation issues. The regulation and charging circuitry is all mounted to the planar and it's pointless to try to diagnose without the schematics.
 
That is totally overheating...

what you got there is the worst combination IN THE WORLD (in my opinion anyways) you have a POWER THIRSTY VERY HOT prescott crammed into a poorly ventelated/cooled HP machine... you should check inside the bios to see if there are some thermal protection options... if thermal throttling is disabled.... ENABLE IT!!!

also check to see if the fan is even on and then more inporntantly check to see if the air is HOT AIR or room temperature air... if the air is room temperature then the laptop's internal cooling is not even working... (probbably due to a poor heatpipe or bad heatsync contact) so if you feel hot air comming out of your laptop that is actually a GOOD THING...

here's a nice flow chart to more clearly explain... (i'm going to keep a copy of this and spring it on other people with overheating related issues ;) )

-1 before you begin you should see if you can blast out the dust from the vents with some compressed air...

0. does the bios show the cpu temperature?
yes and it gets really hot 68c+ --- yep it's definatelly getting hot proceed to step 1
yes but the temp stops climbing after awhile <68c --- it could be something else causing your problem check other possiblities... it also might be possible that the bios is not stressing your cpu... also if it shuts down while your watching the temperature and the temp wasn't that very high then it is definatelly SOMETHING ELSE and it might be a good idea to TAKE IT IN...
no --- oh darn... well if the bottom of the laptop burns you proceed to step 1 anyways...

1. Is thermal throttling enabled in the bios?
yes--- proceed to step 3
no--- go to step 2
there is no option--- go to step 3

2. does enabling thermal throttling fix the problem?
yes--- YOUR DONE
no--- take note of this and proceed to step 3

3. does the fan work at all?
yes---proceed to step 5
no--- proceed to step 4
a little bit--- use some compressed air as in the first step and proceed to step 4

4. see if you can adjust the fan settings in the bios... did this fix the problem?
yes--- YOUR DONE
no--- take note of this and TAKE IT IN TO GET FIXED
no option--- TAKE IT IN TO GET FIXED

5. Is the air comming out of the vent hot or cool?
hot--- if it is hot air then it should be ok but TAKE IT IN anyways also something else may be causing the problem if you beleive it's not overheating...
cool--- TAKE NOTE OF THAT AND TAKE IT IN somethings wrong with your cooling if it's melting and cold air is comming out...
