HP DV7-4285DX: How to clean the fan

Sun, 24 Jun 2018 02:49:50 -0700

My laptop is overheating and i can feel the heat through the case and so l eventually came to the conclusion that the fan is not working but because dust is trapped in the machine. And originally, i was planning on taking it to a computer store so they could clean the fan but I'm trying to save a dollar or two by doing it myself.. Does anyone know how to go about doing that, safely? Because i don't want to destroy my laptop. Thanks.

I applied Colgate on my CPU while I was cleaning my motherboard with spirit.

Now the laptop doesn't want to switch on after the Colgate saga. Is the process reversible?

HP DV7-4285DX: Charge light solid white wont start when HDD plugged in

Sun, 26 May 2019 14:29:59 -0700

I have a slightly different DV7 6143CL When i hook any HDD up to the PC it will only make the charge port light solid white and wont shut off till I take the battery out if I disconnect the HDD and leave the proprietary HDD cable hooked up the computer will give me the HP splash screen and tell me I need to install an OS. I figured if the cable was bad it would do the same thing when i have the HDD hooked up but it doesn’t. Again the charge light stays solid white with no power cable hooked up to the PC when a HDD is hooked up to the PC ( i’ve tried SSD and HDD)
