There is no need to "disable" firmware updates.
The computer will only accept "valid" updates.
So, how would somebody be able to access your computer, in order to try to update the firmware. Prevent access to your computer, and you will have prevented the firmware from being updated.

use the correct firmware on drive, if not the drive will be killed.
if unsure open case and look for name/model on sticker of drive
SOURCE: the OPTIPLEX 755 will not start
Open the case and look at the little black round things that look like soda cans. Those are called Capacitors. they are kinda like small batteries. They should have a shiny silver top. If they have anything oozing out or if they look like theyve popped like a popcorn kernel, then you have a faulty board. If your pc is under warranty, call dell asap. its an easy repair and its done the next day.

Hi,
The problem of blinking amaber light is usually caused due to a bad power supply on the computer. Open the system tower and reseat the biggest bunch pf cable connected to the motherboard. its titled P1 and it the biggest white connector. If the same doesnot resolve the problem you would have to replace the power supply on the motherboard.
Thanks for using Fixya
