Hello,
I have a strange issue with a G62 (b98ed).
The owner asked me to install fresh windows and drivers. Before i did that i wanted to check the condition of the laptop since the owner was complaining that it was really slow and loud.
After booting to Windows i noticed the fan made alot of noise and the laptop got extremely hot.
After installing Speccy the CPU was 73 degrees (celsius) and the mobo/GPU 78 degrees!
After surfing on the internet i saw alot of heatsink/cooler issues with the G series laptops. So i decided to dismount the heatsink (and with that almost completely disassemble the laptop). After opening the heatsink i found alot of dust inbetween the cooler and heatsink. I removed all of the dust and all of the excessive coolingpaste (and there was alot! thanks HP...). I reapplyed new paste and the laptop seemed working fine.
I checked the new temperatures wit Speccy again and the CPU is 42 degrees (celsius) and mobo/GPU 46 degrees which seem to be normal temperatures. After some other checks/loads i cannot seem to get the temperature above 50 degrees so my fix seems to work! The fans are still very loud but there is no more excessive heat coming from the fan/heatsink.
All seems fine!
Now i wanted to do a battery check (the battery seems a little jiffy) and HP support told me to boot to the system diagnostics screen. Unfortunatly my old laptop has no battery check there but there is an option for a system check.
So i decided to run that. The memory check goes fine then the hard disk check.. 5% fine.. 10% fine.. 12% "puck!"
My laptop falls dead. After turning it on again the bios states error 090D thermal error.
As it seems the laptop turned off because it got overheated. The laptop does not feel hot and the air coming from the heatsink also does not feel hot! After directly booting to windows and checking Speccy the temperatures stay the same (40 degrees cpu and 44 degrees mobo/gpu and they stay in that temperarture range).
I would say it is a software threshold problem and not a hardware problem. Now i saw the same problems on the internet and HP support stated to update the bios. So i did that.. Unfortunatly with no effect.
Also hard reset and the other sugested fixes from the HP support page did not work.
The strange thing i noticed from all of my efforts.. The system only seems the shutdown before i start windows. When i am working in Windows nothing happens. But when im in HP diagnostics of the pre-windows-boot HDD check (from windows itself) it crashes after a couple of minutes with the 090D error.
Does anybody have an idea what i can do about this?
I saw one possible fix on this forum and that is to remove the CMOS battery from the mobo and do a hard reset after that. Then replugging the CMOS battery and booting directly into the bios. Will try this later tonight!
