What happens when Dave realizes that this room is actually a storage room

[@h0ll0wm9n]

Dumpster dive AND repair. Dave's best genres for repeat customers.

So pumped to get a link from this channel. Thanks Dave!

[@jacobrodgers2700]

Watching these repair videos makes me want to find broken electronics to fix. Dave makes it look so easy!

[@billmyke746]

Damn Dave, I love your dumpster.

[@NetworkXIII]

[@CarstenBauer]

Well done Dave! Fantastic work!!! Congratulations!

Inductors with window, that's new.

Dave, I when I used to repair displays on macbooks, one test to verify a bad module was to shine a flashlight on the dark LCD. You can see the desktop, after boot. Then you knew it was the backlight module part. Though, with this HP, you figured out it was two issues: bad bios and bad backlight transformer. Great troubleshooting and true trash reward! :)

Holy smokes, who are these companies chucking this stuff out?!? Awesome dumpster. Can’t wait for the new show!

[@matiasgl]

Congrats man! I've just learnt about that damned bell... now I will be notified!

[@ntoobe]

Woww that was interesting!

[@Rcfieldz_Rcfieldz]

Very nice troubleshooting tutorial. Thanks!

"Secret Squirrel USB Port" is frequently used with a cheap BlueTooth adapter to add BT support.

[@fortnitegod2647]

This is a known fault with the bios. Glad you re-flashed the bios . The backlight board has a tendency to go pop so I would replace that as well😁

[@folkertbleichrodt5622]

That was a thoroughly enjoyable video, thanks!

The little pin in the center is usually a one-wire bus for charger identification. There probably is a one-wire eeprom in the connector.

[@WacKEDmaN]

nice fix for the bios..nice they put the SPI header on the board to reflash it..ya dont see that very often on PC mobos

[@stevencarlson5422]

Nice hope you get it all fixed up and can test it to its fullest :)

Hi Dave, This HP Devices usually sends pulses to the Power-LED to simulate a beep if it don't have any Speaker in. On the HP Website you can usually look what that means (it's going from one pulse per second up to 5 pulses per second). What's it usually does is 1 puls = not used, 2 Pulses = BIOS, 3 pulses = "Hardware" (mostly CPU or RAM), 4 pulses = Thermal Problems and 5 pulses = Systemboard (HP Speech for the Motherboard).
