Not bad. Was it an SSD? I ended up paying $60 total for the 120gb msata ssd($45) and adapter($13).

(Side note: OMG the euro dropped far!)

Re: Macbook Air A1237 Power Issues

Hi everyone ,

My problem is that : The charger LED does not light up red and green.Macbook will starts only with the charger.I tried with the new battery but it is the same problem.When it is turned on , there is the message "no batteries available".I'm sure that battery is okey and my charger is original(new).I will try many solutions but still did not help me.Is there any "power supply" on motherboard which is responsible for this ? I mean transistor or something like that ? All in all my macbook is running only on the charger.

Thanks for any sugestions

Re: Macbook Air A1237 Power Issues

Sounds like somewhere along the charging circuit you have an issue. Is it the same model? Id just start at the beginning of the power input and measure from there. Did you look at the schematics? If you look at the beginning (where the battery connects) and start working your way through, you should find it. It could be the battery lines not creating PP3V42 which would not allow it to start without the adapter.

Hmm but the fact it starts up without the charger is suspect...it sounds like its not detecting the battery. So I would try looking at the one wire circuit. Thats usually something to do with no green light.. That or PP3V42
