MBA SMC fail, or charging? Hardware diag fail too. Help.
Hi, was having trouble with an MBA 5,2— very poor battery endurance. Ordered a replacement batt from you and installed. For cal, charged to 100% + two hours, then started to run down to zero. Died after just a few hours, and now won’t charge at all. Reset SMC several times. MagSafe light is orange, coconutBattery sees all zeros, see attached. I tried to run hardware diagnostic (holding D at boot), but it boots into internet recovery, with or without option key. Then throws error “Cannot Load ‘EFI/Drivers/TestSupport.efi”. Any suggestions?

Thanks for your volunteer support Dan!
This Mac is not screen-shotting with normal keyboard commands, so attaching a photo of coconutBattery main window. Been sitting all night, shut down, with orange MagSafe light, and still the same.

I'm suspecting you have a bad battery or the charging logic has a problem but I can't tell from what you've posted.
I get more useful information from CoconutBattery. Can you please take a snapshot of the apps main window and post it here for us to see 기존 질문에 이미지 추가하기
