Tell us the number of times and the repeated cycle, EG:
Power button LED blinks 5 times with 5 beeps
Reseat memory DIMM modules. If the problem is not resolved, contact support to resolve a possible RAM or Main-Board failure.
Power button LED blinks 6 times with 6 beeps
Video Card or Graphics
Reset the graphics card (if applicable). If the problem is not resolved, remove other accessory cards, and replace the graphics card or Main-Board.
Power button LED blinks 7 times with 7 beeps
Motherboard or Main-Board failure
Contact support for possible Main-Board replacement.
Power button LED blinks 8 times with 8 beeps
BIOS or CMOS problem (ROM)
Perform BIOS recovery with external media (USB/CD-ROM).
The main area (DXE) of BIOS has become corrupted and there is no recovery binary image available.
Also happens when updating BIOS.
Typically no steps needed.
1. Allow the system to complete its updates and changes.
2. If updates are stalling, attempt Sure Start Recovery.
The embedded controller policy requires the user to enter a key sequence.
1 Follow any prompts given.
2 If issue persists, attempt Sure Start recovery.
The embedded controller is checking or
recovering the boot block.
1 Allow the computer to attempt to recover the BIOS.
2 If after several minutes the issue persists, attempt Sure Start recovery.
