Aspire 7720g Wireless Card Not Detected

applemaca · 02-07-2012, 04:26 PM

Hi, I was giving my 7720g it's bi-monthly check over for dust in air vents and all, took the Ram, fan, heat sinks and cards out and vacumed up any dust. I replaced everything (or so I thought) and turned on......Black screen! Then I notice I had not replaced the ram. Shut laptop down......removed battery, replaced ram, turn on laptop....everythin is fineg except wireless LED blinks Rapid and constant & Wireless pro ABG card is not showing in device manager.

Anyone have any idea why? I've un-installed, removed card re-installed drivers, reinstalled card and still the same......HELP!

Running windows7 64bit.

What happens if you move the ABG card to the other slot?

wireless LED goes out & still no wireless.

Card is not detected in the other slot either.

The card is dead, then.

Yip....managed to get a hold of replacement today. Was only when fitting that I realised I had used a magnetic screw driver when refitting the old card......doh!

I'm guessing that's what caused the failure?

I don't think it was your fault- magnetic screwdriver shouldn't do any harm.

My 7720g is 3 years old, I have never cleaned anything and it works fine. In my opinion, if something works ok it is better to leave it alone.

that's all very well............until the day it doesn't work!

There's a thread here somewhere referring to problems folk have had with blocked heat sinks causing overheating problems.
