Question about HP Compaq Presario C769US Notebook

1 Answer

Compaq Presario C769US PC Laptop heats up.

Lower left, just below keyboard, gets VERY hot after PC has been on for a couple of hours. It's usually on all day, but I do shut it down if I'm not going to use it for a couple of hours. It is cool again when I reboot. I don't remember it running hot when I bought it - September '08 I believe it was.

    Dear mbonnstetter,

    Thanks so much! Amazing how we forget to search all around, therefore overlooking the obvious.

    I responded to someone who has the same laptop as me, who couldn't find the webcam. If the persons' pc really is the same model, it's literally right in front of our eyes! So I was able to help that person with as obvious a possible solution as you have helped me.. My dad used to say "if it had been a bear it woulda bit ya". It appears that one heat sink is plugged with dust. Surprise, surprise. I wll look into the cooling unit, though.

    Again, thanks much. I think you just saved me a bunch of cash :)

    Steve

Right under that area of the keyboard there is a heat sink. If you look in the bottom of your laptop, in that area you will see a vent (and another towards the upper area of the bottom of the laptop). These vents are to keep the internal devices cool.

You can buy a laptop cooler online or in the store

From the manual:

Hotkeys are combinations of the fn key (lower left of keyboard) and one of the function keys:

Mycompaq presario c769 us get hot so much


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

My laptop makes a continuos loud, beeping sound when i turn it on


First try drying the keyboard with a hair dryerand leave powered off for a couple of days. If you need to change the keyboard or disassemble the laptop to complete the work, I usually purchase the keyboards on Ebay for under 25 bucks.
