After battery replacement random shutdowns on battery power only
I ordered & installed a replacement battery for my mid-2010 17” MacBook Pro. I tried to calibrate it per the iFixit instructions, but when I was trying to run down the battery, the computer shut down for no reason at about 80% battery. After I plugged it into a power supply I was able to start it again and it still showed 80% battery and then I let it sit overnight to die for the battery calibration (I did not keep an eye on it so I don’t know at which point it crashed, and I let it charge in the morning for several hours before using it again).
In short, this has continued to happen intermittently when I am not plugged into a power supply. The computer will randomly shut down when there is plenty of battery power left and it still shows as having plenty of battery left after I reboot. I had no issues like this before replacing the batter — the old battery did not hold a charge for long but it also did not shut down randomly.
Things I have tried:
-Running Apple Hardware Test (results normal)
In System Profiler the battery status shows as “Normal”.
Is there anything else I can do? Is my battery just a lemon? Can I get a refund? If I have to be plugged into power for the computer not to crash, I’m no better off than I was before. I am a musician and I use this laptop in live performance so I cannot have it randomly crashing.
Questa è una buona domanda?
