by mferna14Hi, my dear friends., Maybe this might be a stupid question or something I missed or do not know. I have 2 MacBook Air A2681 (Indentical color & EMC #), both LCD screens broken. Before ordering the LCD Screens I confirmed both worked with their respective batteries & AC Adapters, & they did 100%. The LCD Screens came in today & I replaced LCD for the 1st A2681. (Removed Battery Terminal cable for both Laptops before installation of LCDs). Perfect Screen & Booted up fine. But it did not work with battery. I checked the battery connector & it was seated in well/perfectly....

by kais99399Hi everyone
I have a A2681 M2 with a weird charging issue. 3 days working on it without any success . It’s only pulling 5V 0.20A on the USB-C metmeter. The macbook actually boots and reaches the login screen only with the battery connected. If I try to run it on the charger alone (battery disconnected), it doesn't boot at all. My known-good board boots fine on the charger without a battery.
What I've found so far:
Battery Rail connector : Ppvbat_aon_conn. Diode mode is 1830
First usb C When I plug cable power, I measure volt at the fuse F5200 seid ppbus_aon... -
by TimScrawnI have an m2 air A2681 here today that is just giving 5v @ 0.025amp draw. No liquid damage or prior history of repairs. No power at all. Checked the following lines:
PPDCIN_AON_CHGR = 5V
PPBUS_AON = 12.36v
PPBUS_5vS2_VIN = 12.3v
PPBUS_3v3_S2_VIN = 12.3v
PP3V8_ON = 3.8v
PP1V05_S2SW_VDD2H = 0v
PP1V25_S2 = 0v
I have replaced U5200, R5215 & R5216. Checked ohms on both resistors. Both tested good. Little bit stumped on this one. Any help would be greatly appreciated. -
by MarpolexHi I'm having a weird issue with a2681, everything works besides detecting usb-c charger and charging while turned on. So it is charging while its off (turned off ,not lid closed) if i disconnect battery it starts to detect charger while turned on also if I connect 5v while turned off it takes 0.45A and when powered on it stays that way and charger is been detected. No visible liquid damage....
