HP G60 / G62 Laptop Overheating Problem & Cooling Repair

Serviced an HP G62 laptop recently, that was shutting down randomly and customer stated screen would distort at times.

HP G62 Laptop Overheat

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:

HP G62 Cleaned Heatsink
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.

HP G62 Cleaned Fan Exhaust

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.

HP’s Poor Manufacturing

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


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

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 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.
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.

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.
HP Laptop After Cleaning
Same Heatsink Above AFTER CLEANING >>>>>
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.

Heat, overheating is a big problem in ALL laptops.
HP G62 Laptop Motherboard

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.

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.

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 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.

Temperature Monitoring Programs:

Core Temp
Hardware Info Tool

Every laptop owner needs to have a temp monitoring program running on laptop. Prevent laptop overheat problems BEFORE major problems begin!

    Guess thats what happened to mine. I’m disabled & pretty much homebound & poor & my lap top is very important to me wish I had this info earlier.I can’t use desk top my hands are bad for mouse. Anyway would like to know if any one knows of a pretty good laptop on the cheaper side that may have fewer problems? One that just crashed/fried was HP G62.Or where I can get a pretty good deal? Appreciate all this info here thanks.

      Run away from anything HP or Compaq in the future. There all designed cheap, and usually fail within 12-16 months or so. All laptops develop a heat problem eventually due to dust accumulation on the inside, as you see in the photos. The problem with HP is they designed these laptops very well knowing it, poor thermal paste, lightweight thin heatsink, cheap thin motherboard that can’t handle excessive prolong heat at all.

    this article is on the money! took my girls g60 apart as its been running slow, sounds like a jet engine every 60 seconds and very hot. the dust ball build up looks exactly like the picture. after removing and putting back together, works like a charm. thank you for the article!

    Thanks for this. I just re-pasted my [now redundant] G60 and despaired at the fact it is still no better. I didn’t know to check the heatsink exhaust! Thank you – screwdrivers are coming out to play again later 🙂

      Separate the fan from heatsink “fins”, that is where you’ll see it blocked………… most likely

    Hmm. So, okay, HP is junk when it comes to the quality of the parts they use and the design. What laptop brands do you recommend?

    • augustapcrepair February 10, 2016 at 7:20 pm Reply

      Lenovo, Asus, MSI, Samsung. “Night & Day” difference in design, engineering and quality built components compared to HP, Dell and Toshiba for the most part. However, all laptops will develop heat problems in time once the heatsink exhaust becomes blocked by dust & lint on the inside. Fan intakes air, along with dust, hair and lint. Needs taken apart to clean properly eventually.

  7. Priya June 24, 2016 at 8:45 am Reply

    Such a great article, thank you so much for this. I sent my G62 laptop for repair two years ago. They cleaned it and replaced the fan, but that only worked for a short while. The condition is really bad now, so I will be sending it to clean again. How often do you recommend to clean the laptop?

    • augustapcrepair June 24, 2016 at 12:03 pm Reply

      Keeping a small can of compressed air around, and blasting vents out periodically when the laptop is OFF, will help. In attempt to “light” buildup inside blown out, BEFORE heavy buildup happens. Laptops fan intakes cool air from outside the casing, along with dust, lint, hair etc. Depending on your working environment full internal cleaning 1-2 years maybe.

    Hi, sorry for my bad english but i;m frustrated. I have a HP G60, I clean up the laptop, change thermal compund, try to replace the heatsink, buy another processor, and the temps still the same, 70 C on idle and 104 C on youtube. My computer is lost? I’m thinking in buy another fan, (I have lubricated the original fan). Anybody can help me?

    • augustapcrepair August 17, 2018 at 11:28 am Reply

      With thoroughly cleaning inside (fan & heatsink exhaust grill), properly applying small drop of thermal paste on processor, tightening down heatsink to cpu you should not be operating that high of temperature. Very old laptop now, would not invest alot of time, or money into it. Cannot help thru messaging, email etc.
