Troubleshooting steps
|
|
BIOS
|
2.2 (blink)
Caps Lock LED blinks red 2 times followed by 2 white blinks.
|
The main area (DXE) of BIOS has become corrupted, and there is no recovery binary image available.
|
Perform BIOS recovery with external media (USB or CD-ROM). For information on how to restore the BIOS refer to the HP support document: HP Notebook PCs – Restoring the BIOS.
|
|
Hardware
|
3.2 (blink)
Caps Lock LED blinks white 3 times followed by 2 quick blinks.
|
The embedded controller has timed out waiting for BIOS to return from memory initialization.
|
Reseat the memory. See the section Reseating memory modules in a notebook for more information.
If reseating the memory does not resolve the problem, try replacing the memory modules, or contact support for repair due to a possible RAM or system board failure.
|
|
3.3 (blink/beep)
Caps Lock LED blinks white 3 times (slowly) follwed by 3 faster blinks.
LED blinks are accompanied by beeps. Red blinks have a lower tone and white blinks have a higher tone.
|
The embedded controller has timed out waiting for BIOS to return from memory initialization.
|
Contact support for repair due to graphics or video failure.
|
|
|
3.5 (blink)
Caps Lock LED blinks white 3 times (slowly) follwed by 3 faster blinks.
|
