How to desible Dell optiplex 755 Frimware updates


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.

We received a donation of Dell Optiplex 755 Mini Towers. I can determine which and the proper order of LAN/Network driver (1,2,3 etc.) installations.


Find your specific model on http://support.dell.com
First, look for a "chipset" device-driver. If it exists, install it first, and reboot.
Second, look for an Ethernet device-driver. Download it to a USB memory-stick, and move the memory-stick to the Dell, and install it.
Third, the order of the other device-drivers does not matter, but having a working Ethernet connection makes it much easier to download/install the other device-drivers, and also to run "Windows Update" to download more device-drivers directly from Microsoft's web-site.

if its a small form factor unit then you may need to get a video card that is Low Profile
and also consider the power supply :
The ATI Radeon HD 4650 512MB Low Profile PCIe x16 graphics card should work fine with the 275w PSU.
Max power draw is 48 watts

Optiplex 755 flashing orange power button light only


Sounds like you only have power going to your motherboard.

The power supply might be bad on it, that or maybe the power cord is going bad and is only letting a small amount go through. I don't see why there should be a problem if you have even a little bit of power going though.
