Picture of HP Compaq Presario F500 repair
 Hi! This will be very first tut! I have been lurking for a long time, now its time to contribute!

Difficulty: 3 out of 10
virtually no experience in computer or soldering is needed.

If you fallow these steps and something goes array i am in no way responsible, but i will try to help if you have any problems :)
If you are not gentle and careful you might damage the internals of your machine farther.

GROUND YOURSELF BEFORE TOUCHING ANY OF THE INTERNAL PARTS! (place your hand on a large metal object, you only need to touch it for a few seconds)

Before you start you should be sure this really is the problem your laptop is having. HERE is a link to HP's site, try to see if you can still get your machine professionally fixed for free, better fix.
Basically if you have the fallowing problem this is for you: machine wont start after pressing power button, all lights will come on and HDD will spin and fan will start, but it shuts down after a few seconds and keeps doing this over and over, also no video on computer. 

I know these model laptops also have a bad wifi problem, but this tut will not solve that.

PLEASE HELP!!! I am replacing the plastic keyboard frame only on my Compaq Presario CQ50-215NR computer. It is the plastic frame that covers the power and WIFI buttons and surrounds the keyboard. I have the replacement part but need instructions. I am not doing anything else except replacing this part. Can anyone provide me with instructions? MANY! MANY! THANKS!!!

I would use something like J.B. Weld to to secure the penny to the heat exchanger so it stays in place because all you need is for that penny to come loose from the paste when you happen to move your laptop and ZAP you just fried your motherboard not criticizing just trying to help you keep your laptop for as long as possible :)

It actually did stop working after i did this, so i fixed it again but it stopped working within days. The laptop is now in pieces in the attic, maybe ill try to jb weld it sometime. good idea!

Now that I think about it maybe the jb weld may not hold you could get a small drill bit an drill 2 holes in the coin one on each side and wire it to the heat exchanger like a bread twist tie to hold it.

very smart fix! could this fix some other laptops too?

HP/Compac had this same problem and there was even a class action lawsuit regarding this same thing there is even an instructable on here about that but it is way more complex requiring a heat gun to remelt the solder and the use of a copper shim plate to take up the gap.
