MBP Late 2011 Charger not enough power.

[ivoruest]

Hello to everyone,

I'm quite worried that my MBP Core i7 has not sufficient power from the charger and starts draining the battery. The charger is 85W, but after some googling I found that this Mac can consume more than 90W so not only does it stops charging but it starts using the battery power to feed the thirsty machine.

Have you found any solutions to this?

FYI: I discovered this while playing Portal 2 (which is not a highly demanding game) in High Settings and running Windows 7 x64 in Bootcamp.

Specs:
Macbook Pro 15 Late 2011
Core i7 2.4Ghz 4 core 8 thread 6Mb L3 Cache
8Gb 1600Mhz Ram
Seagate Momentus XT 500Gb
AMD HD Radeon 6770m 1Gb with the 12.4 Catalyst
Windows 7 Pro x64

Any comments on the specs?

It's normal for MacBooks to use power faster than the charger can supply during periods of intense usage. During these times, the battery should only drain slightly, so unless you are using it like this all the time, you should be ok.

Ok, thanks for the reply. Do you know if there are higher power chargers compatible with this MBP? Will it do any damage to the battery?

The maximum power supplied by the Magsafes is 85W. No, using the Magsafe adapter obviously does not harm the battery.

I wouldn't be worried,playing Diablo 3 for 3 hours only drains my battery 7 percent and it takes like 14 min to recharge once i stop.
