Problem :
After loading a driver for an external usb wifi adapter, this laptop is having issues booting.
Symptoms are:
Boots up but loops after 15 seconds or so, don't know if it is actually posting
Black screen (as in screen does not turn on at all)
Things tried:
Pulled all memory, all peripherals and reset CMOS battery. Then inserted 1 memory stick with no changes.
Pulled battery, no changes.
Any ideas of what to try next?
Solution :
First, this is not a driver problem as bootup doesn’t involve drivers. If the machine does not POST, pull the hard drive and see if it POSTs. If it doesn’t its time to call HP. If it does boot into cmos reset to defaults, and try again.
