i'm rather new to repairing non-apple motherboards. this boards has a problem with +3valp. I was getting a low resistance to ground on the rail and i injected 1v. the pch got warm so removed it. the short seemed to be gone but when it comes back when the charger is connected. i'm getting 5v...

this board is charging the battery because it ramps up to 1.8 amps on the meter. it will go into dfu and it will go through a revive but it never powers up at all. pm_slp_sus_l is 3v . pm_slp_s5_l is 0v. is this a chipset issue?

i'm confused about this board. the battery doesn't charge and the fan ramps to full speed everytime. only one usb-c port works everytime and sometimes the other does. the board appears very clean with no signs of corrosion. Can this board operate without a working battery?

this 820-2915 board works and then sometimes the fan will ramp up and it gets laggy. sometimes it passes the diagnostics and sometimes the tm0p sensor error.

i have 2015 a1419 and the camera doesn't cut on. it also pulls down the 5v_s0_camera_f rail to 3.48v when it's connected. bad camera?

Can i get support here for an alienware area 51m r1?

3v3_g3h is 3.3v and 3v3_g3h_rtc is 3.3v. ppbus is 12.24v

the efi and OS diagnostics both passed. the only strange thing that i notice is that chgr_bgate is 0.9v and it charges really slow. u7000 has been replaced several times and q6910 was replaced

I'm familar with the logic boards that existed before usb C. This data bus should be working with or without a battery? u7000 was replaced and the resistance of r5380/r5381 both measure around 2k. ppdcin is 20v and ppbus is 0v and I think it's because smbus_smc_5_g3_sda is missing. the battery...

this one is pecular because it hesitates by about 10 seconds before it beeps without the ram installed and when the ram is installed it hesitates before the cpu vcore drops to .8v like it should but it doesn't want to post. i'm not sure what to check. all rails are present as far as i know

pp3v3_tbt_t_f is shorted to ground because of a water spill that got under ub000. ppdcin stays at 5v. could this be the issue? i've replaced both cd3215 chips on that side

this board suffered from water damage and qb400 is burned and needs to be replaced but seems almost impossible to removed it without damaging the contacts on the board. is there a technique to lessen the damage?

the board is entering all the power states but i'm not getting all_sys_pwrgd. i'm not sure which rails to check for

this machine was powering on even after a cola spilled on it. i decided to clean it for safe measure and now it doesn't power up. i found short to ground on pp3v1_rtc. i'm new to the touchbar logic boards. i looked at the schematic but i'm still lost as to which chip creates pp3v1_rtc and is it...
