HP G60 / G62 Laptop Overheating Problem & Cooling Repair

Recently serviced a HP G62 laptop, that was shutting down randomly and customer stated screen would distort at times.

HP G62 Exhaust Fan

Installed a temperature monitoring program on the laptop. And just booting up to desktop, “idle temperature” was 79-87 celsius, which is overheat high temperature range, especially on laptops. Began a malware scan, and within 20 seconds temperature went from 82 celsius to 116 celsius.. red zone, fry temperature.

I immediately stopped the scan, and shut the laptop down. Disconnected cord and battery and opened this HP G62 laptop up. Cooling Fan & Heatsink cooling grill was completely blocked off with dust build up.

If you are here reading this article, and your laptop fan is very loud, sounds like a jet engine ready for take off constantly, randomly shutting down on it’s own, 90% of the time the fan exhaust inside of the laptop looks just like some of the photos in this post!

Dust, hair etc buildup on the laptops internal heatsink exhaust is the #1 cause for overheating in your HP G60 / G62, and ANY laptop that is overheating and ready to die completely. And the automatic “random” shutdown of the computer or laptop is a thermal protection feature, trying to warn you and protecing the laptop from complete overheat failure,, DO NOT IGNORE IT.
 
 

2-15-13 – Another HP G62 Laptop

HP’s G60 & G62 are very similar laptops. Both laptops are very susceptible to motherboard failure due to high heat, every laptop is. HP’s cheap components (the motherboard) on these models fail at a very high rate. The laptop only has 1 cooling fan, only 1 vent to exhaust the heat out of the laptop. Laptop cannot exhaust the heat once the internal heatsink vent becomes blocked like this with hair, dust, lint, sand, food etc. The laptops cooling fan runs very loud, at high speed constantly trying to cool down the laptop, even with 0% cpu usage going on.

Do you have your important data backed up? If not you better backed that up, for this type heat can, and will damage the hard drive also. Hard drive = where all your important documents, photos, etc are stored. Main heat problem is a blocked internal heatsink exhaust, other minor problems pertain to HP’s poor choice of design & material used inside of the laptop. Discussed further below….

HP G62 After Cleaning and Cooling Modification Repair:

On A Still Functional HP G60:

Idle Temperaure After Repair = 40-47 celsius
(Before repair 82 – 116+ Celsius)

Load Temperature After Repair = No higher than 62 celcius.

And what’s important is how quick the laptop cools after “under full load” ends.
 
 
Remember now, very top of this page, this HP G62 hit 116 celsius within 20 seconds! 116 celsius = 240+ fahrenheit!! Water boils at 212! Laptop IS NOW operating much cooler. Was any long term damage done by the heat it was operating at? Visually cannot tell, the laptop and it’s hard drive has already been exposed to this high heat for how long I do not know. So yes, the high heat that this laptop was operating at, even though cooling has been repaired now, could still result in failure relating to the pre-existing overheat conditions. There is really no definite answer.

ALWAYS, keep your important pc data, photos, music, documents backed up with ANY laptop!

Cleaned Heatsink Exhaust Vent

If your fan is running very loud constantly, laptop keyboard & bottom area feels VERY hot, and laptop is freezing up, with random complete shutdowns. The internal heatsink exhaust grill as in pictures, is most likely blocked from the inside with dust etc. Combine this problem with the poor quality manufactures applied thermal compound used on the CPU & GPU breaks down overtime also.

Why The HP G60 / G62 Overheats?

#1 – Owner Neglect – Lack Of Preventive Maintenance
#2 – HP’s Poor Design & Cheap Components – Cooling System & Motherboard
 
 

Owner Neglect – Lack Of Preventive Maintenance -

Lack of keeping intake vent clear, lack of owner periodically blowing out air vents, and how, where you use your laptop… the environment. Using the laptop on a bed for example, blocks the cool air intake vent off on bottom of laptop, suffocating the laptop from cool air = overheat conditions. Using laptop on bed, blanket, carpet etc…. hair, dust and lint fibers a now have a direct route into the laptop. All electronics attract dust as it is, and the laptops fan does at one time pull cool outside air into the laptop. Along with that air that cools your laptop,,, dust, pet hair, lint, sand, food particles etc.

These HP G And “DV” series laptops are prone to overheating, partly due to HP’s poor choice in materials on the inside also.

HP’s poor choice in design and the material used inside of there laptops is the reason for warmer than normal temperatures. HP’s thermal pad does not transfer the full heat generated by the video graphics chip (GPU), to the copper heatsink. Poorly applied thermal compound, poor quality thermal compound that breaks down overtime. Main heat source is the processor / cpu, the graphics chip sometimes sits very close to the cpu chip.

Do you really think HP is going to cover any warranty for a dead overheated laptop, when they find dust, hair, lint, pet hair, food particles found inside of your laptop blocking the exhaust vent? Even with HP’s admitted design defect, this dust blockage HP will classify as “user abuse, neglect or abnormal working environment conditions”.

The “Overheat”, hotter temperature electronic can damage (motherboard, hard drive, graphics hardware) comes from long term, excessive heat build-up inside of the laptop caused by dust, hair, lint, food, debris etc blocking the internal heatsink exhaust on the inside. When the build-up inside becomes this heavy as you see in photos, the laptop must be disassembled to clean it properly.

Overheat Symptoms:

- Temperature monitoring software reporting constant temperatures above 70++ celsius.
- Keyboard & bottom of laptop are extremely hot
- Slow down in laptop performance
- Laptop randomly shuts down on it’s own.
- Distorted display, lines or scrambled screen – video hardware overheat – defective possibly
 
 

Overheat Motherboard Failure Symptoms:

- Power lights, LED lights flash and turn off
- Power lights on, no display on screen, caps light flashing
- No power lights, no display, caps light flashing
- Power lights, caps light flash on and off – laptop does not turn on
- No power on at all (Also Broken Dc Jack Symptom)
 
 
DO NOT ignore the overheat temps, do not ignore the automatic shut down. The laptop is automatically shutting down due to excessive heat, built in protection feature of the cpu. The laptop NEEDS to be disassembled & cleaned thoroughly from the inside SOON! Heat is the #1 cause of complete failure in ALL laptops.
 
 

Overheating Consequences:

- Hard Drive Failure. Long term heat will shorten the life of, and damage the hard drive.
- Complete motherboard failure. Very expensive repair IF replacement motherboard is available.
 
 
 
Overheat & Failure Symptoms listed above can also point to a few other areas such as:

• A bad dc power jack connector inside of laptop – no power, no battery charge. Use a multi meter to check power cord, try another power cord, test dc jack from inside of the laptop on motherboard with multi meter.

• Bad or loose memory modules.

• Random shut downs can be caused by a virus, driver issue or damaged operating system.

• Distorted display could be a bad or failing lcd screen – check with external display.

Install a temperature monitoring program like Core Temp, IF your laptop is still functional/boots. If your laptop is pushing 70+ celsius just sitting idle, your laptop is overheating & in trouble.

Laptop Cooling Repair & Modification Service
 

Blowing the vent from outside of the laptop WILL NOT clear or clean this heavy build up inside. The hair, dust and debris have no where to go but right back into the heatsink exhaust grill! This type heavy build up inside IF blown clear can jam the laptop fan up completely, which can burn the fan out.

HP dv9000 Fan Before cleaning >>>>>

Have seen this dust blockage baked onto the heatsink exhaust vent due to the heat temperature, where it needs to brushed off first, then blown out with air.
 
 
As you can see in the last few photos, the fan “housing or outer casing” on the fan needs to be removed in order to check, AND clean this area. If you DO NOT take apart the fan, separate and clean where it meets and exhaust heatsink grill where the dust, hair etc accumulates it will overheat after reassembly.

Old thermal paste needs to be cleaned off real good with rubbing alcohol, polished clean (rubbing alcohol evaporates).

Fresh quality thermal paste needs to be applied.
IF you do not do this, laptop WILL overheat.
 
 
 
 
 
 

Same Heatsink Above AFTER CLEANING >>>>>

This is the way it should look for good cooling.
 
 
The fan housing, fan cover must be completely removed from fan/heatsink (3 or 4 very small screws) in order to see, and clean any dust blockage where fan meets the heatsink exhaust vent.

This is HP’s very poor choice of material on the inside of most of there laptops.
Picture on right, from another HP model >>

2 Red arrows point to the GPU & CPU contact points on the heatsink. The the silver “tape” area is HP’s poor choice of thermal material, aluminum tape garbage.

The other red arrow points to the blue thermal ‘pad” HP used, another poor material choice.

These areas are carefully scraped off, cleaned & polished, modified and good quality thermal compound is applied to these areas.

HP dv2000, dv6000, dv9000 series laptops have a similar overheat heat problem, resulting in graphics hardware display failure – no display, black screen. These HP “DV” series laptops have the setup similar to what you see in photo above. HP laptops in general I tell all here to avoid around here, poor design, poor materials, cheap motherboard resulting in a variety of heat related problems and complete failure of there laptops.
 
 
 

What HP calls quality thermal paste >>>

This is from a HP dv9000 laptop.

This is what HP uses on the cpu. Aluminum tape thermal garbage. If you truly build a laptop to last, YOU DO NOT build it with this garbage!

The CPU produces a massive amount of heat.
Why does HP, the manufacture build a laptop this way??

This gets scraped – cleaned off and quality thermal paste is applied. Arctic Cooling MX2 is the best.

What Is Overheat Temperatures On Standard Laptops?
- Idle temperatures of 65+ Celsius is considered to warm – the laptop has a cooling problem
- Contiuous temperatures of 75-80+ celsius, your laptop is overheating
- 80+ celsius on the cpu is basically shutdown temperature

That is IF it auto shuts down, auto shutdown might not work. If your laptop is running 80,85++ celsius you need to clean it or have it serviced soon! Higher cpu’s run hotter, it is important to have the right setup inside, and a clean heatsink exhasut fan.
 
 
 
 
Gaming laptops run a bit differently, and run a bit higher due to the higher end cpu & video card. But all the same I don’t like seeing laptops pushing over 65+ celsius constantly with no cool down. Computers, laptops will all “peak” out under full load maybe 65, 75+ celsius for example, but when you are down playing a game, watching a video,, done with “full cpu / video load” it should cool down to a respectable idle temperature in the low 50′s. If your laptop is constantly running 65, 70 celsius, that laptop is in trouble!

Processor / cpu’s can handle high temperatures of 100, but inside the tight quarters of a laptop, with poor cooling, it is very bad, no good for the rest of the electronics,, hard drive and the laptops overall speed & performance. And the cooling defect that causes video failure in the HP laptops, that is due to excessive heat melting the solder connections under the video graphics chip.

If the old temperatures on this laptop would have continued, this HP G60 laptop would of been dead fairly soon, a paperweight! I recommend ANYONE with a HP DV series OR G series laptop to have this cleaning, cooling modification done. Otherwise your laptop will be junk, burned up electronics.

HP G62 Blocked Fan Exhaust

These HP G and DV series laptops were built, sold new off the shelf operating very close to overheat temperature, due to the use of the thermal pad HP installed on the video graphics chip, and crap thermal compound or aluminum pad on the cpu. And once the fan inside starts to become blocked, this restricts and prevents the hot air to exhaust out of the laptop.

95% of the time I find the internal heatsink fan exhaust blocked by dust build up in ALL laptops. Keeping the cooling vents blown out periodically from the outside should prevent this from building up inside. Once it builds up thick inside, it cannot simply be blown out.

Heat, overheating is a big problem in ALL laptops.

HP G62 Laptop Motherboard

Take a good look at a portion of the HP G62 motherboard to the right >>>

The motherboard, mainboard is the “heart” of the laptop, all hardware is dependent on the motherboard. All communication, operation is channeled throught the computer motherboard.

Extreme Heat can result in melted or very brittle solder joints an ANY of those circuit chips.

Internal “traces” or circuits within the motherboards PCB can short out and fail.

Keep in mind 85 celsius = 185 degrees fahrenheit, water boils at 212 fahrenheit.

All it takes is one faulty, damaged, overheated circuit, chip, or inner board “trace” and the laptop is now a paperweight.

If the laptops mainboard fails, your basically in for another computer, hard to find replacement for a laptop, not available for replacement for laptops, not repairable, and if a “used” laptop board is located… not reasonable or smart to repair.

Looks Brand New Doesn’t It??

It’s “DOA”, Dead, No Life, Junk

It’s exhaust fan was completely blocked so bad fan was jammed up, and would not even rotate by hand!

 
 
 
 
 
 
The laptops motherboard is the #1 culprit for laptop failures. Dropped laptops, liquid spills, loose dc power jack, and overheating can & can damaged the laptops motherboard permanently. Desktop motherboards are fairly cheap, and there are a variety usually to choose from. With laptops, the only motherboard that can go in that laptop is the exact same part# it was built with.

How To Prevent This Overheat From Happening?
With ANY laptop……………..

- Especially when new, keep a can of compressed air handy, once every month when the laptop is OFF, blast the exhaust vent out. Your goal here is to keep that inside fan exhaust clear of heavy build-up as you see in these few pictures on this page. If it is heavily blocked as these photos, the ONLY way to properly clear it is to dis-assemble the laptop and clean it properly. The heat is so bad I have seen this heavy dust hair build-up, BAKED onto the inside heatsink exhaust it will not just blow off. If it does blow off it has no where to go but jam your fan up entirely or go right back into blocking the exhaust again.

Keeping the exhaust vent blown out often on the laptop will help keep the fan area clear inside. The only true method is to disassemble laptop to clean and replace the thermal compound. A complete “tear-down” should be done about once per year, if you cannot perform the job, take it in for service.

Cooler Master NotePal X2 Laptop Cooler

- DO NOT use the laptop on bed, blanket, couch or carpet. The laptops cool air intake vent is on the bottom of the laptop. A bed or blanket conforms, or wraps around the base of the laptop suffocating the intake vent off, overheats the laptop. Lint, dust, hair, dirt will pull directly into the laptop from this type material.

- Keep the area where you use the laptop clean. Wipe your desk or table every now then.

- Use a USB laptop cooling pad. These special design laptop coolers elevate the laptop off table a bit, and blow cool air towards bottom of laptop, helping the temperatures.

Note: IF the laptops fan is blocked on the inside, a USB laptop cooling pad will not work. The heat buildup inside the laptop has no where to go, exhaust is blocked heat increases.

Arctic Cooling MX2 Thermal Paste

 
 
Arctic Cooling MX-2 Thermal Compound I have tested against Arctic Silver 5 thermal compound, actually does a better job cooling by a few lower degress than Arctic Silver 5 or Arctic Silver Ceramique.
 
 
 
 
 
Arctic Silver 5:
- Well known product for it’s thermal transfer cooling properties
- Cure time 200 hours (gives best heat transfer)
- Needs to be re-applied after a year or 2 (No problem for desktops)
- Contains silver, which means it is conductive, need to be careful on application of.

Arctic Silver Ceramique:
- Almost as good as Arctic Silver 5, 3-4 degrees higher temps
- Cure time 25 hours (gives best heat transfer)
- Non-Conductive, will not short out near by components

Arctic Cooling MX-2 Thermal Compound:
- 3-4 degress higher temperature over Arctic Silver 5 Thermal Paste products
- No “Cure Time” (best heat transfer once applied)
- Non Conductive, will not short out near by components
- 8 year durability!
 
Arctic Cooling MX-2 Thermal Compound has been the “go to” thermal compound for desktops, gaming computers and laptops for me! Non conductive, 8 year durability, no cure time and good heat transfer qualities explains it all.
