    Hi

    What I want to ask is how did you get to the motherboard after step four. I couldn't see how you removed the upper protection plastic part.

    I couldn't get it out either!!!

    I wish you good work.

    Be cautious when removing the adhesive strip. Pull it straight ( not up) from the battery a little bit at a time. It is longer than you'd think.

    Spot on instructions. Be sure to seat the battery connector very carefully and make sure it doesn't pop off. It look me several tries to seat it.

Hi,

After replacing the battery, we now get an error “Temperature too high, will shut down” when we boot. We get the same error with the old battery installed. We tried a factory reset. That did not help. I’ve rechecked steps, and it is pretty straighforward. Any ideas?

Thanks,

Dave
