I have a 1420n that I recently updated from 7.04 to 7.10 and then 8.04.
All seems OK except some resume from suspend issues:
- no backlight
- often no wifi, apparently network disabled.
When I boot, I see that my Bios is A01.
Over at Dell, it looks like A09, 7/14/08, is available [and recommenced] for download for 1420.
Is the Bios the same for 1420 and 1420n?
Anything I need to do before downloading the A09 Bios?
Is there a tutorial re how to do this?
