Macbook Pro 13 early 2011 "no batteries detected"

[hemmjonny]

Hi guys,

I hope someone can help. I have an early 2011 Macbook Pro 13 it was working OK but now has come up no batteries detected and I have tried a pram reset, smc reset and a new battery but still no luck.

I did manage to get it to work for a while by turning it on with the power adapter connect then restarting it but at the point of the restart I pulled the power and it came on with the battery.

If I start it with the power adapter connected and then pull the power it will boot to the login screen briefly then go into sleep until I reconnect the power.

I am out of ideas and I am ment to be giving it as a present to my girlfriend at Christmas :-(

When the power adapter is connected it just has a solid green light at all times never changes even if I do the smc reset.

I really hope this can be repaired if anyone has any ideas it would be very much appreciated.

Thanks in advance

Jonathan

If you've already replaced the battery it may be a board issue. I've actually never seen a "no batteries detected" message. Since it's a new battery (and presumably a new connection cable) it may be the socket where it connects to board. I'd recommend taking it to get serviced at your nearest Apple Certified Repair Center.

Sounds like you may have a bad battery. Work on getting another replacement.

Thanks for the replys. I cannot see anything obvious on the board. The battery was tested before I put it into my mac. I really hope it's not the logic board but I guess it's looking likely :-(.

I think like you said I may need to take it into apple. Do you know if they charge for diagnostics?

Or has anyone else got any ideas how I can repair this problem.

Thanks again

Logic board :-( over £300 to repair. Not worth doing

is there an X on the battery or does it just say it is not charging? X on the battery is usually bad pullup resistor R5280/R5281 or bad SMC U4900. Measure signal end of R5280/R5281 to see what's up.
