Greetings to all. My probook 430 G5 (3KY88EA) does not start anymore. I'm not sure if it has been caused by Windows 11 update to 24H2 but after applying this update the notebook went of unexpected for serveral times. No error messages, no entries in Windows eventlog or BIOS log found.
After several times going to off the notebook does not start anymore. Blackscreen and beepcodes as well as caps log blinking lights indicating: 1time (2x long 2x short - BIOS) followed by repeating 3x long 2x short (Memory)
allready replace memory, tried to restore BIOS following the instruction provided by HP - unfortunately without success,
BIOS Q85 01.28.00 Rev.A; 2x8GB RAM; 512 GB SSD (Windwos OS); 1TB HDD
Updated through HP Support Assistent an a regulare basis - should be up to date
Any hints for restoring the BIOS are welcome.
Best regards and thanks in advance
Herbert
