Re: HP ProBook 450 G3
450 G3, two long two shorts, BIOS corrupted. Got laptop as non-working.
Serial 5CD6104L89
Flashed BIOS from https://www.badcaps.net/forum/showpo...68&postcount=2 and it boots and works, but after BIOS update from Windows to new version, charger is not working. Flashed back via programmer, working.
Also, I thing there should be dGPU, but not showing.
Please suggest other BIOS
Many thanksLeave a comment:

by AhariHi all,
This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.
I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

by Habble7The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

by studdy05Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

by CityminHi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)
