Re: Acer ChromeBook CB514-1HT Bios Password Locked
I have 2 units (Chromebook CB514). Both units lock by administrator. I managed to reflash the first unit using the new generated BIN file (I have the original bin of the first laptop). However, on the second laptop I forgot to save the original BIN, and the data of the chip is already flashed. Now my laptop has no display anymore even I use the original BIN on my first laptop. Can anybody here can help me to fix my laptop bios please.

Hi everyone,
I’m working on an HP 255R 15.6" G10 Notebook PC that has a BIOS Administrator / Setup password I cannot bypass. I can boot Windows normally, but F10 is completely blocked unless the password is entered. I do not know the password.
This is not a Power‑On Password. This is a BIOS Admin password stored in NVRAM, and the system will not allow BIOS access at all.
I’m posting here to get help identifying the correct procedure, dump, or method needed to clear the password on this model. System Details

Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅... -
Looking for some help with an Acer laptop.
Model: [Nitro ANV15-52]
SNID:55121732376
Serial Number: NHU1NAA001551350EB7600
Current BIOS Version:
After updating the BIOS, I lost access to BIOS Setup due to a Supervisor Password lock. The machine itself is completely healthy.- Windows boots normally.
- Zorin Linux boots normally.
- F12 boot menu works.
- Only BIOS Setup access is locked.
- BIOS generates a challenge/hash file.
I'm attaching the challenge file/hash below.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows
