Re: HP Probook 430 G5

I have tried all bios's found on this forum for this range of laptops, and they all give a constant white charging light for 2-3seconds, with three orange flashes. pressing and holding the power button for 12 secs doesn't help.

Any chance of some help please?

Re: HP Probook 430 G5

Please could someone take a look at the BIOS dump in my first post?
Ordinarily I would download a virgin BIOS from the manufacturer and have a look in o migrating info, but in this case HP only provide a 12MB UEFI BIOS region with a load of padding. I've even tried downloading the HP PC HARDWARE DIAGNOSTICS 4-IN-1 USB KEY - SP105879, but again it only contains the above mentioned update and not a full Intel BIOS.
I have already tried replacing the ME region with a clean one using FIT, but i got the same result as with the original dump - perhaps...

Agreed, use the BV. If that fails, try powering the LT on and off leaving the AC connected, then connect the clip and perform the flash/verify? Using the 'Detect' button is useful to get an indication that the clip is seated correctly if it returns the chip ID.

Also, have you checked the voltage at pin 28 of the CH341A chip with a DVM? Mine was using USB 5V, and would have been sending 5V data signals before the 1st mod mentioned in my earlier post.

@Stylishh11

Have you read the chip name from the chip itself, or relied on the programmer to detect and tell you? Perhaps it is a W25Q128FW 1.8V?

Did you make several backups in the first instance and compare them prior to carrying out any modifications?

You'll need version 1.18 of the CH341 programmer(other versions are problematic with this chip), AS Programmer 1.41, or Colibri to program the chip if it is an FW. Also how you connect the chip makes a difference.

HP Probook 430 G5

Greetings, and thanks for a great tool!

I have a Probook 430 G5 - P/N: 2SY09EA - MB/N: DA0X8BMB6G0 REV:G
Chip: GD25B127DSIG

Currently it doesn't boot, and will only illuminate at all with the AC out, and the power button pressed for 12 seconds. CAPS LOCK and power light illuminate for around 2-3 seconds then off, no fans at all.

It was reported to have had bitlocker enabled(probably via TPM) with a BIOS password, previous owner had attempted to re-install Windows 10, and someway through it died and has been in...

Hi All, Great forum Topcat, hats off to you for starting this so that others may learn. I've been using our companies user account here on Badcaps for years, and thought it was time to create one for myself!
