Thinkpad T530 fails to charge battery
The battery is FRU 42T4793 and had already run out of juice. BatteryInfoView shows 78% on a T420
Plop it in the T530 and the battery icon blinks green quickly three times, pauses, then blinks more slowly seven times in amber, one more time in green, and then stops blinking.
”Charge” for 30 minutes, pull the plug, hit the power button, and there's no reaction.
The AC adapter is 90W. No hard drive installed, but the T530 generated a message about the failure to support the installed battery. I can’t replicated that message so far.
Same battery works as expected when placed in the T420
I can replicate the behavior on the T530 with another battery, FRU 42T4791
I actually have a replacement system board at the ready, but what else can I try before swapping out system boards?
