Remove the wireless card drivers, then goto this directory to reinstall them.
This happened on both my 7405 and my 6811, worked fine after. I think you grabbed a bad update from the windows update.
Try the bios update, it is posible that it was misflashed, but not during your CDROM firmware flash.
Did you try removing all power sources and the cmos battery and letting it sit overnight? That is of course after you short the two terminals in the battery socket.
Follow my RAM guide to access the heatpipe assy. Remove the 4 screws to remove the unit. Then remove both fans and literally wash the heatpipes in soapy water and dry with a hair drier. Then remove all traces of the old thermal interface material and coat with fresh.
Yes it will, but our Motherbaords will only run it at ATA5 or 100 MBP/S. The physical nature of the hard drive will never allow it to even come close to the ATA5 standard, so your are not loosing a thing over ATA6.
Make sure to use pricegrabber, as Zipzoomfly was cheaper than newegg and had them in stock at the time I bought mine.
A CMOS battery will indeed produce the same exact symptom except for the lack of power light. A CMOS battery will NOT affect the blue light. Depending on the BIOS, the charger portion of the motherboard may or may not be controlled by the BIOS code. On some dells the battery charging algorithym is coded into the bios.
I suspsect a bad motherboard or a bad AC adaptor. One of the two.
Tested your drive today and it works great. The only problem is it struggles to play DVD's. It is jerky and the sound skips. But all music/data CD's work fine. It could be that my Dell does not like the firmware or the DVD laser calibration is not correct.
Being you did not ship the cable, I recommend getting a new one and giving that a shot before ruling out major problems.
Check your PM.
