Not a company just doing this as hobby project.
a1707 was stuck on 5v, I replaced c6906 and c6905 caps, because of my bad soldering I had only soldered the c6905 cap on one side, but this made the board run on 20v. It turned on works fine, when connecting battery and the battery ribbon it would just power cycle on when reaching 10v.
I resoldered the c6905 cap. Now I have a board that struggles :
20v only kicks in after a while.
cap connected: (5v for good 2 minutes)
PPVIN_G3H_P3V3G3H: 3.8v
PPDCIN_G3H_CHGR_R: 5v
PPBUS_G3H_R: 0.6V
(20v stage)
PPVIN_G3H_P3V3G3H: 20v
20v takes time to kick in, sometimes minutes. When I connect the battery ribbon the board power cycles the second the voltage reaches 10v, and power cycles over and over. The laptop works without a battery but I specially bought a new battery from ebay as the old one was bulged up.
I ripped the d6902 pad but I soldered d6902-d6906-d6905 together as they are on the same ppvin_g3h_p3v3g3h rail.
