Jul 30, 2017 2:18AM PDT

Ok so I have hp laptop out of warranty which turns of itself after 10-15 seconds..i checked it,the fan is working properly and hdd is also fine..whatever I do,it just shuts down in 1-10 secs...i gave it to two repair centers,and they said that they need to replace the mother board as they didn't got to the exact problem..but getting new motherboard is costly,so need to figure out the problem myself and try to fix...can anyone help me??i can attach the photos if someone wants...i have tried cleaning the fan and applied thermal paste on the cpu and removed the old one..

that symptom

is almost always due to an overheating problem. If it boots fine and then shuts down, something is overheating or motherboard part has failed. Be sure the CPU has new thermal paste between it and the HSF.

Worth trying. Replace the heatsink compound.

While you are in there you can check if the heatsink stays down and contacts the chips it is cooling. Button it back up and test. If it still does the shutdown, then some chip has gone south and it's a new motherboard to fix.

Will this work?

I noticed that my heat sink seems to be corroded...some part is brown copper and most of it has become black...can i do something about it??i was thinking of applying thermal paste on that...can i do so??or will it further damage it??

Time to watch some heatsink and paste videos.
Jul 30, 2017 8:14AM PDT

The paste does not go on the areas that need to pass heat to the air. Brown copper would be fine and black could be fine too. But even if it was black the few seconds its working points to something far more wrong than a little corrosion on the heatsink fins.

Maybe I was unclear. Replacing the heatsink compound is a few dollar roll of the dice and gives us a chance to be sure the heatsink is buttoned down and installed properly.

If you want a for sure fix then you are looking at a new motherboard or PC. I always try the few dollar thing before I go for a big money fix.

PS. The lack of details
Jul 30, 2017 8:16AM PDT

Without make or model, age I can't add much to this discussion. There are some models that are known to fail like this and you don't repair. You don't consider motherboards. You tell the client to move on.

Nothing looks bad on that model.

I worry about the corrosion at what looks to be a model that is just over a year old. Was this subjected to outside use?

Doesn't look that bad. Just paint bonding issues.
Jul 31, 2017 9:08AM PDT

That looks like poor paint bonding and not corrosion.

Anyhow, your story, the review and my experience tell me to give the heatsink compound replacement a try since it's cheap. There are some clients that insist we fix it so for them we write up a new battery, motherboard and charger since that's about all that could be failing here.

After the heatsink compound you retest and if it fails but say runs windows but doesn't game any longer, move it to some lighter duty like web surfing and shop for your next gamer.

Be sure to find reviews like notebookcheck, CNET and others and avoid models that review poorly like this one.

Laptop cooling issue
Jul 31, 2017 2:05PM PDT

It appears you have a cooling issue. Some laptops flat out are BAD!!!, they tend to destroy its own ingrated video source due to heat. Further, if cooling is reduced due to vent clogging or fan failure that too generates the same issue and can lead to video destruction. The cure is to teardown and chk. video area for any burnt or discolored areas. -OR- cracked plus disconnected solder points. Alas, if this is found usually too late to repair other than mtrbd. replacement. If some fan issue, remove and replace to be sure its operating 100%, up/down RPM as required. The vent issue is where exhaust is impleted or reduced because of dust clogs. You have to usually remove fan assy(entire) to access that area and verify its clean. Also, as stated to you, the heatsink compound should be replaced as well properly since you have it tore down to cover all bases. If you like your laptop, look for exact model replacement, that cost maybe cheaper than repair&labour via Craigslist or eBay. Once brought you can swap storage media alone and restart w/o issues.

Heyy there..thanks for your reply and all others...i have removed evry part and clraned fan,laptop base and removed all dust...i know replacing heat sink is a good idea but can there be an issue with processor...i heard from a person that my processor could have been fired...if that's so than also motherboard to be changed or only processor (i know that costs too much)

NT - you still have the problem?
Aug 1, 2017 9:06AM PDT

If you need a new motherboard/processor (some are embedded on laptops), then might find replacement on EBay. Just be sure same exact type so your OEM recover/restore windows software will work on it.
