HP Wireless Module not found

All of a sudden my old compaq presario gave the "Wireless Module not found" error on startup.

I have googled all kind of solutions (power drain, driver update...), none worked.

Then I have watched this video:



I have grabbed a screwdriver, opened the lid, and I discovered that the card was not properly inserted in its socket - probably a mechanical shock pulled it out.

I have tried to report this SIMPLE but NOT MENTIONED solution to HP forum, it was impossible to add a reply...

Anyway.... this is just to say that not ALL SOFTWARE error messages are originated by SOFTWARE issues.... sometimes hardware fails, even only for mechanical problems...
