Hi All,
I'm a bit of a budget PC hardware enthusiast and I found the forum because I'm trying to update the BIOS on my HP z420, and the files are no longer available, and found a post here with recent activity instructing how to take care of the issue, so hopefully this solves my issue.Comment

Hi guys, Damo here....i have a HP ZBook Fury 16 G9 workstation laptop that i purchased rather ignorantly thinking it was agood price only to find out it may be because it is a brick.
im. Trying to simply reset it entirely and start fresh but upon completely reinstalling windows 11 once selecting mt counrty and keyboard layout it is forcing me to connect to a network to which it then wants me to sign into my work or school network and can not proceed past this point?
Any way of getting around this and COMPLETELY resetting this thing??
Thanks guysComment

Nuovo utente appassionato di elettronica e riparazioni GPU
Salve a tutti,
mi chiamo Alberto , sono un appassionato di elettronica e mi sto avvicinando al mondo delle riparazioni di schede video e altri componenti hardware. Attualmente sto lavorando su una scheda ASUS R9 390 8G Strix e sto cercando schemi elettrici o boardview per comprendere meglio il layout e i componenti coinvolti.
Mi piace condividere esperienze, imparare dagli altri e, quando possibile, contribuire con le mie conoscenze. Spero di trovare qui una comunità attiva e disponibile con cui confrontarmi.
Grazie in anticipo per il supporto e per i consigli che riceverò!
A presto
