In response to Dan’s request on my original thread (Can I just switch in a new logic board with no problems?), here are image captures of battery information: BATTERY “A”: The battery that was inside the laptop when I dropped the laptop The laptop & backlight do now work with this battery in (for some reason). But • it makes a strange sound (long, slow whirring) when you switch on the laptop •  the fans are running very loud. • The Magsafe is amber — but I think it always has been like that. (Because it’s a non-OEM battery?) BATTERY “B”: The battery from my spare A1278 MBP. • I believe this is an Apple OEM battery. • Laptop works fine with this battery in. • Magsafe is green. BATTERY “C”: A brand new Runpower battery I purchased last week Laptop initially would not recognise this battery when I first purchased it – it wouldn’t boot up. Now, suddenly, it works. But: • the fans are running very loud • the Magsafe is orange

*FIXED* (sort of). I had the same problem for 2 years and it drove me mad. (I had purchased AppleCare but they said it classed as "accidental damage" and wasn't covered. They quoted me GBP £850 to get the jack out, ffs! i.e., they would just replace the whole logic board, as they said the audio port couldn't be replaced on its own. So angry with Apple after this, what a waste of money. What bad service.) In the end, after 2 years of fannying around using a USB-port audio stick every time I wanted to have sound — and after trying (and failing) to use the Q-tip + superglue trick, which just got glue stuck in the port — I got so annoyed by the inconvenience that I took the logic board out and was able to drill out the broken jack from the other side. I did take pictures of the operation – I will try to find them and post them – but basically, from the inside the audio jack port is a grey plastic box surrounded by copper plates. 1) First, I separated the copper plates from each other. (They are each connected...
