HP EliteBook 850 G3: Power LED blinks white and orange

Sun, 30 Jul 2023 09:03:30 -0700

This is the second machine I've seen in a week with the same problem, or at least very similar.

The one on my bench presently is an Elitebook 850 G8, the one I replaced a system board on was an Elitebook 845 G7. As soon as any type of power is connected, either battery or AC adapter, the charger LED will turn on white, but blink amber simultaneously. I believe it blinks 10 times. I have been unable to find any documentation for this specific error. This persists even if I remove connections from the system board to any other hardware aside from whichever power I am connecting. Even trying to power on with no RAM gives this error, will not beep/blink to indicate the system does not detect RAM. I do not even need to indicate power on for this to occur. As soon as there is enough contact with whichever connector to transmit the necessary power, it starts.

I have even tried running a BIOS recovery to no avail. This 850 G8 on my bench seems as though it will try to power, keyboard backlight will come up, Caps lock LED will light steady, no blink codes. It's under warranty, so ultimately it's probably going to get a new system board, but I want to know what this error is.

HP EliteBook 850 G3: Flashing power light, not turning on

Wed, 21 Feb 2024 16:00:08 -0700

Hi everyone, I have this HP EliteBook 850 G3 which has suddenly stopped powering on. It was working fine last night but coming to it this morning it won't power on anymore, all I get is a few flashes from the power light. The keyboard backlight comes on and so do the mute and WiFi lights. I've tried hard resetting and removing the battery. I can't seem to find any code that matches the flashing on this.

Any help would be appreciated. Thanks in advance.

HP EliteBook 850 G3: Why does my display 'solerize' at odd times?

Sun, 20 Sep 2020 00:03:09 -0700

my display ‘solerizes’ at odd times - to ‘fix’ it - I either close and open the lid or reset the display refresh to another rate but neither is a permanent fix.

Recently I found out there is missing screw from my HP EliteBook. This causes one side of hinge open with a "crack" noise and open up. Is there way to fix it without replacing the screw? If not, what size of the screw should I get to replace this missing screw

HP EliteBook 850 G3: Log in / security key - code unknown. Refurbished by Amazon.

Refurbished by Amazon yet it appears they neglected to remove previous owners’ passcode. How do I erase it and replace it with a code I know?
