Product: HP Z440
Operating System: Microsoft Windows 7 (64-bit)

Hello All, 

I have an issue with my Z440 I have no post issue with solid light on Caps, Num lock and Scroll lock. 

I have tried all standard troubleshooting still the same issue.

Has anyone come across this type of issue ever?

Please help......

@IP-LOG -- when you power-on your computer, it launches the POST (Power On Self Tests).

 

Your symptoms, namely all the lamps being lit-up, is an indication that the POST has detected a problem, and is using those lamps to indicate "this computer has a problem".

 

It could be the power-supply, the RAM, the video-card, the motherboard, or the CPU.

 

Do you have the technical skills to partially disassemble your computer, and then to "part-swap" those components (if you have compatible "spare-parts") to try to isolate the "bad" component?  If not, it's time to hire a qualified computer technician for trouble-shooting.
