Yea motherboard is working great with charged battery. The problem is that is no longer able to identify charger as 19v and therefore is unable to charge batteries.... -
Hello!
Not sure how to do it, you mean to inject 19v on some points to see if motherboard works this way?...Leave a comment:

Hello and thank you for reply!
UT5 has many pins and i want to leave it for last. I will try PU700.Leave a comment:

Can someone please help?
Still trying to figure out why motherboard identifies as 5v instead of 19v.Leave a comment:

Hello.
Had a small delay for 2 reasons, first i ordered and received a lot of working 7410 so now i can take measurements from a fully working board and comprare.
Second i managed to get boardview https://www.badcaps.net/forum/troubl...01#post3785901
So the Source Gate on fully working is 260K. Is this the normal resistance or 175K is still low?
UPDATE: took measurement on faulty...Last edited by Andreasbest; 12-16-2025, 01:08 PM.Leave a comment:

Managed to get my hands on boardview
Hope it will help us repair the amber led of death.
Have fun!...Leave a comment:

On the donor board is 200k
It's confirmed really low?
If it is then perhaps this is the fault on the donor too.Leave a comment:

Source Gate 175K
Gate Drain 6M
Source Drain 0.8M...Leave a comment:

I cleaned the short but still same voltages.Leave a comment:

Look what I noticed on PQ801
There is short between Gate and Source...Leave a comment:

I get 50K this way.
Meanwhile found a Russian forum with the boardview but i can't pay with european cards due to sanctions

No idea where the PR822 is, still searching
Meanwhile PR811 has 5v on one side and 0.7v on the other side that is connected to pin#6 of PQ807.Last edited by Andreasbest; 12-08-2025, 02:01 PM.Leave a comment:

Well i don't remember, if i reported 5v then i should have measured 5v.
Do you want to solder the old one back and see if i get voltages?Leave a comment:

Yes it came from a donor board with other fault (can't power on, amber LED only) BUT identifies the 19v correctly so i assume it was ok.
I resoldered all 6 pins, now i get 5v on pin#6 but pin#1 and #3 are still 0v
Do you want to resolder the old one or order replacements?
Or perhaps something else.Leave a comment:
