Hello everyone! I have an old hp workstation z420. Xeon E5 1620 v2, 8gb ecc ddr3

Basically, when I plug in the power cable to the power supply, it turns on and off while clicking every time it power cycles. Once I remove the power cable from the supply, it flashes a red light 4 times while beeping for about 10 seconds. I have purchased a new CPU and power supply already, but that hasnt fixed it so I'm convinced it's a motherboard level fault. If anyone has any ideas on what the fault could be, and/or how to diagnose it, that would be highly appreciated. Thanks!

Hi,

as noobie to this please excuse my lack of experience.

I am trying to remove a BIOS password from this machine:
[B]HP ProDesk 400 G6 Mini [/B]

but so far I still have no success.
I bought [B]CH341 programmer[/B] and decided to give it a try.

The programmer came with [B]8 pin [/B]cables and connectors or whatever everything else is called so I had to buy a new [B]16 pin cable[/B] because the chip which I think is the BIOS is with [B]16 pins[/B]..

Is the only way to resest/delete the BIOS passwort removing and reprogramming the bios chip? Or is there any other easier method?

Hello all,

I am trying to remove bios pw from this laptop so I desoldered, dumped and flashed and resoldered the chip on the back but ever since doing this caps lock just flashes 7 times, no fan no screen, also the charging/power light immediately comes on when connecting the battery.

What do I do?...
