G73jh - shutting down - help

Hello everyone

I use my G73 mainly (if not only) plugged in, never on battery
Since yesterday, the PC simply shuts down totally, right in the middle of whatever (can be playing a game, browsing, just idle next to me...)

Pressing the power button even often does not relaunch it, i have to close the lid, wait for a few mins, and relaunch and there it works again...

No error message, no blue screen of death, it simple gets to black screen + fans off and that's it...

Did anyone experience this ever? Any idea where that might come from (i'm not really a tech guy)

Thanks!!

 

keep your hands near the fans ,do you feel like burning? I ment to keep your hands over vents. and when it happens does any light remains?
turn off your laptop , hook up an vaccum cleaner to the vents and get all the dusts from it , see if the problem is fixed.

 

Sounds like overheating to me... Clean the vents with compressed air, and if you haven't you might want to consider having your system repasted with a high quality thermal paste. Seeing as you aren't technical though, you'd likely need some assistance with that.

The compressed air cleaning should help some though, so I'd try that first. I'd also make sure that both of your cooling fans are running.

You can try to run Furmark and that should give an idea on your GPU temperature which on full load should not reach > 90-95 degrees at the very most (my system at load usually hovers around 80 I believe).

In any case, this definitely sounds like overheating.

 

Hi all,

yes thats what i thought at first (overheating) though even if the air at the back of the PC is warm, it's not THAT warm :-/
When you propose compressed air, can i just spray it over the fan at the back of the machine? or do i have to open it ? (if i spray hait there wouldnt it push dust further in the PC?

I'll try furmark to see

 

lol dont use compressed air it will push the dust further inside.Madnj use a bit of your sence .
btw: use a vaccum cleaner so no dust will get into laptop, use it in higest speed no dust remains in heatsinks. do this for both cpu and gpu.

 

Sorry to be stupid but... i have to OPEN the laptop right? Or just vacuum on airgrids is enough ?
btw, my GPU is between 86 & 90 right now, just browsing, CPU is at 60 (good? bad?)

edit : just mlaunched a stupid game like wow and it goes up to 94° on start screen
edit 2 : 105° in game, wont launch Crysis i guess

I'll try to open the thing (that is what you mean right?) and vacuum it

 

Here's how to clean your G73: G73 clean out - YouTube

Your GPU is definitely shutting down to prevent heat damage. I mean mine is running at full clocks right now, ~25% usage and it's not even hitting 65C at ambient temps of 24C.

 

Are you serious? Compressed air pushes dust further inside? No... the dust is gunked on the fans and in the fins of the canal where the airflow is... Compressed air will spin the fans and dislodge much of the stuck dust and force it out the same fins you are blowing into.

It makes perfect sense to use compressed air to blow into the back of the case because the dust will come right back out the back....

A vacuum will likely not have enough suction to pull all of the dust out which is why I made the recommendation. In any case, this is definitely overheating and whatever you can do to clean out the vents/fans should help your temps some.

If you are idling that high, you either have a really bad GPU paste job or a ton of dust clogging up your system. If clearing the dust doesn't drop your temps by a lot though, you're likely in the position where you need to have a repaste done on your video card (which you probably should NOT attempt yourself and I'd only trust a professional or highly technical hardware savvy person to do).

 

There are vacuums designed to clean electronics and those usually work well, but a regular vacuum is likely to not have enough suction as well as creating static that could result in damages components. The chance of static caused by a vacuum resulting in damage is low, but better not any chances unless you completely dismantle the laptop and remove the heatsinks to clean them which i advise against.

 

Hi everyone,

Update : followed the video there (glad i had that compressed air bottle sitting in a drwer since 2 years )
Fans are bearly audible now, idling at around 55, and went up only to 74 after 30mins of gaming. Definitive improvment!!

Thanks again for the tips

 

Excellent! Thanks for the update. It's amazing to me how much dust can raise the temps on these systems...

Glad it fixed things for you.

 

Glad your problems are over. I'd give the laptop a good dusting every few months.
