I turned off my dell n3000 series during update. After that my dell always black screen with one beep on strat-up and fail to enter BIOS. What should I do?
Thanks in advance
If you're under warranty, call Dell -- they'll replace the mainboard.
If you're out of warranty, you have two options:
1. Replace the mainboard, or
2. Find a shop that can un-solder the BIOS chip, flash it in an EEPROM writer, and resolder it.
The two options are likely to be similar in cost - a couple of hundred dollars.
