Extremely slow charging? (Possible ceramic capacitor issue?)
Greetings,
I have an old Early-2009 MacBook Pro 17 A1297 that charges extremely slowly.
I'm not a professional when it comes to electronics.. but here are my observations:
The issues:
- Extremely slow charging = ~8 hours per 30% charge
- plugged in MagSafe adapter board always gives full (i.e., not "dim") green light (while charging, when charged.. so always: not red color can be seen)
- logic board seems to have a missing ceramic capacitor C9709. How's that gone missing really? :)
- I guess this is the culprit... but anyone can confirm this?
Other:
- MacBook boots always (thank God)
- no "slow computer" issues
- DC board is not the nicest one I've ever seen but it seems fine to me
- no sign of corrosion or burnt areas
- MacBook's battery and the MagSafe adapter are fine (both genuine too)
- already have tried:
- resetting SMC, NVRAM
- cleaning the port with isopropyl alcohol
- putting another genuine, working battery in the MacBook to see if fixes anything (it did not)
By the way, isn’t the capacitor C7910 a bit swollen? It seems the be a bit.. overgrown.
Thanks in advance.
