Hello everyone,
Like many others, I updated my laptop's BIOS using the HP update, but I'm left with a blank screen. Unfortunately, I tried flashing the chip with the basic HP BIOS, which didn't save the corrupted original one. I wanted to ask if I could use the model and serial number to try to restore the PC. I think the original HP BIOS 08328 should be used.
Thanks for your help.
My PC is an HP 250 G6 with an i3. Sn: CND8082H27 ProdID: 2LB53EA#ABX Motherboard: CSL50/CSL52 LA-E791P REV 2.0

HP messed up by using same BID for 6th/7th gen and 8th gen, same board number, same BID, diferent CPU generation
Latest version for 6th/7th gen CPU is F.52 08328"B" variant, extracting just by running the .exe you will get 08328"A" variant for 8th gen
Do not update to newer version, it will brick
Afterwards fill S/N, product name, etc with HP BCU

Thanks for your reply, and sorry if I posted in the wrong section.
I'd like further information on how to enter the serial number, model, etc. into the BIOS you attached.
Thank you for your kindness.Comment

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

Hello first post!
Ok so after an (ASUSTek) optional Windows update, my old ASUS E403NA laptop rebooted and froze in the BIOS menu screen and was unresponsive so after about 30 mins I powered off and back on again. Now i just get a power LED and a black screen, I have tried all the basic suggestions and all the suggestions on the ASUS site, spoke to ASUS support who said I will need to pay for an RMA.
The laptop is worth €50 so I won't be doing the RMA at god knows what price.
So I have seen some videos where people have reprogrammed the BIOS...03-07-2024, 08:31 AM -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
