If you’ve ever encountered the HP Wireless Orange Light of Doom you already know how annoying it can be. For those of you who don’t know what the HP Orange light is: Basically the internal wireless card in the machine stops working and no longer shows up in Windows Device Manager and the machine appears to no longer have a wireless card.

I can't post urls yet but basically this tech has simply cleaned the contacts on the wireless card with a flat head screwdriver and they have worked fine ever since.

i tried this on my laptop and it worked then my wireless card disappeared from my device manager but the light was still blue any help on y this is happening

awesome

Man I don't know how or why that worked, but I am impressed. If you are anywhere near the GR area and need some auto repair I can hook you up with some free wrench spinning

Which Fix

Did cleaning the contacts with a screwdriver work or the heat treatment?

The bad copper makes more sense to me and that would explain the heat fixing it temporarily at least. Hp should replace the thing if that is it , that would be a perfect example of a factory defect that should be repaired w/ or w/out a warranty.
I will not hold my breath .
I have a friend who is an expert in metallurgy. Perhaps the contacts could be tinned with silver solder?

I tried cleaning the contacts for the wireless card and got no results. I did put the card in another laptop to be sure it was functioning. Typed in "everest ultimate" into my google browser and downloaded AIDA64 Extreme Edition. Once I had that I used masking tape to cover the vents for the cooling system ran the "system stability test" located in the tool bar. About 10 min into it I changed my screensaver to the "bubbles" and previewed it as soon as the bubbles came on the wireless came to life. I was able to turn it on and off with the switch but after a shut down I had to do it again....only took 5 min this time but it seems to be when the bubbles come on is when the light turns blue. If i need to do this again I will tun the bubbles on as soon as the CPU gets up to 80.

That program is a free trial version to download I actually ordered a mini usb wireless adapter the night before I did this and think I could have kept my $10 in my pocket

update

a few days after doing this I had a complete failure of the motherboard. I shut it off one day and the next time I tried to turn it on it would start to power up and then shut right off. After doing some research I found that people have been baking their motherboards in the oven to "reflow" them. with nothing to loose I gave it a try 385deg for 10 min and it came back to life.

I did video the procedure I used and will be posting it on youtube shortly.
