![]() Find the wattage in the AC Charger section towards the bottom: If your Mac uses USB-C to charge, you can charge your Mac laptop with any USB-C power adaptor or display. Seems to charge for a bit, cut out, charge for a bit. Look for the certification label on the power adaptor, which lists the wattage (W): Hold the Option key and choose Apple menu > System Information, then select Power. This brought up the voltage to 11.4 volts or so.Īt this point I put it back in the Mac and the mac now recognised the battery and it charged. I have a hobby charger for charging model aircraft batteries so can set it to 3 series and with a couple of bare wire ends stuffed in to the battery slots, take care to get polarity correct.then I gave it a 10-20 minute charge. So, 3 series is maximum of 3 x 4.2volts = 12.6volts The pack is 3 lipo cells in series 2 in parallel (3s2p) configuration. If you put the battery down on the desk, as if fitted to the Mac, with the test button and lights down and the top of the battery up, with the battery connector slots pointing towards you.įirst narrow one is Negative, last narrow one is positive I found the pinout for the battery and checked the battery voltage, it was down to about 9.8 volts and the lights on the back, only the first one lit.and flashed on/off. ![]() I bought a new cheap Amazon battery, and the MacBook A1181 2006 would not recognise or charge it. Here is what solved this same issue for me 2007 Apple MacBook Pro 15 A1226 Core 2 Duo 2.2GHz 2GB 120GB OSX NO PSU AS-IS. I also went back to 10.5.x to install apples battery fix 1.4 (doesnt work on sl) Apple MacBook 2007 Model A1181, Black 13' works - no battery. I have also reformatted and installed osx all over again. Apple MacBook A1181 - Black - Mac OS X - No Charger. Sometimes the light on my battery flashe but its completely dead from not charging. Apple MacBook 2007 Model A1181, Black 13' works - no battery. When i shut it down, unplug it n plug it back in the charge light goes amber for a minute or two then turns green. Anyone who's experienced this before have any advice before I go investing in this older but great laptop would be greatly appreciated.Įdit: Everything runs fine, I get the black X in the battery icon. Im now looking into getting a magsafe dc in board or a new logic board. I have tried a new charger, new battery, PMU/SMC reset but nothing has helped. I cannot find a pinout for this battery I can work with, so I’m hoping someone here has one I can use to at least jump it and see if it’s the battery or motherboard.I have late 2006 macbook that has seen better days, A wile back the battery stopped charging and gave me an X symbol. This protects the user, but requires these to be jumped to use them once it happens. I’m suspecting charge rejection because modern BMS boards (even copy onses) have onboard lockouts that create this problem. I’m going to keep the notebook if it works (even though I’ve moved onto something newer, since I don’t want to waste this one) but if it doesn’t I’ll relegate it to a throwaway loaner with the caution it can’t charge batteries until it gets worse. I’m going to keep what I put in minimal for safety reasons unless I somehow need more (3.7V max to start). Since I do not know if the notebook even works (or if the motherboard is bad), I would rather not buy a battery and see if my existing unit is jumpable to get it to a state it’s going to even work at all. ![]() I also see it does hold a few mV of charge with a multimeter. The battery gets mV of charge if I constantly mess with the adapter, so it’s trying but either the computer is forcing it to stop when it does it’s sanity check or the motherboard has issues keeping it going. ![]() I need to cut power off before it even attempts to register it. There are times the battery doesn’t show up when I tried to make it try by running without and replacing it.Charge light comes on briefly but goes to green within seconds.Since the notebook can’t charge the battery and it shows every possible sign of probable motherboard damage, I’m seeing how I can jump the battery the notebook came with to try and see if the signs are board related. I know this may not work so I’m setting my expectations low (expect it to not work, but hope it does). Since I have largely given up on my A1181 (Late 2006) since the charge issue looks to be extensive and it needs other parts replaced, I don’t want to spend money if I can avoid it.
