Can I charge my MacBook Pro from an older iMac?

Solution 1:

There's no other way of charging a 2012 MacBook Pro than through the MagSafe power port. If that has stopped functioning, you cannot charge the laptop as usual.

Your options are primarily:

• getting the MagSafe power port repaired
• taking out the battery and charging it externally and put it back
• take out the hard drive or SSD (depending on model) and transfer data externally

To recover the files I would prefer the last option, taking out the drive. It is an ordinary SATA interface, so you should be able to buy a cheap USB-to-SATA interface at most computer stores, that would enable you to transfer the data to another computer.
