Asrock Fatal1ty B450 Gaming-ITX/ac wont boot, cpu phases turn off after a few seconds. Bios?
Hi I'm working on that asrock motherboard. It had shoted mosfet on cpu phase(changed) and 1 cap on bottom side(changed). Led driver is probably shotted too because voltage on one leg of this chip is 0.5v to 5v (its in loop rising and falling) its's RT7905 and i cant find datasheet :/ But its only led driver so mb should work without it. When i desolder it on the same leg is 5v all the time.
If i start mb on all cpu phases is 1v1 for a few seconds only. Other voltage are present. So i tried to flash bios with the newest on official site and it doesnt help. Its not normal extension... -
Faulty was oem ac adapter, I changed it with other and circuit starts working normal. 3v3 on detect pin.Leave a comment:

Dell Latitude E7440 battery not charging only works on AC Adapter LA-9591P
Hi, i have problem with dell E7440, battery is not charging. Idk all story. Original Dell Adapter broken up (its not give 19V) i guess first ac adapter broken up and it broken charging circuit in laptop. Laptop has clone battery (Green Cell)
Laptop works on clone adapter, and its not charging battery. Like on photo. I checked mosfets near battery plug. They are not shorted. But on PQ809 and PQ810 are low on diode mode (both 0.25V) I desoldered them and check on bench and they are good both 0.5V on diode mode. I checked only drain - source way. So its board circuit it should be higher,...
