Hi all,
My HP laptop suddenly just died. Nothing shown on screen and red light when charger is connected. I’ve done the basic tests to understand the problem and is down to a faulty motherboard. Apparently is common to have a diode burnout in Hp laptops…
On the diode/continuity mode on my Multimeter:
The first diode (107 0J) on the photo I get a reading in one direction and no reading when I switch the poles - so Diode is OK,
However the other 2 diodes ( my multimeter beeps in both directions!? Are they both faulty or is this a type of diode that let current flow in both ways?
Much appreciated!
