![]() ![]() So, what do you mean by "foolish" and "what then"?Īpple recommend calibrating the battery when you buy a new Macbook and then every few months, or monthly if it used on mains all the time. Its not a reserve I "suggest" it is how it works. What happens when that reserve you suggest is there is used up? What then?" "You are completely mistaken and even suggesting that it won't harm anything is very foolish. Is there a reason this happened and should I get it looked at? BLUESTACKS OLD VERSION 10.6.8 + 3+ + + PRORe: My Macbook Pro ran out of battery last night and wouldn't turn back on even when connected to power for a period of time. This takes some time on a completely discharged battery, and it needs some time to slowly start charging without kicking the current in. ![]() And I can tell you that the Apple batteries are very advanced technology, and they have not just a charging/protecting circuit built in the MBA and MBP, but enormous complicated circuits to check and charge all cells per cell. The same has been said more or less by Ogelthorpe, with links to more information. Why would it take 30min-1hr to charge enough to turn back on when it had only died for about 1 minute? Finally, when I did open the computer this morning and it was working, all the settings had reset. Also, the fact that I plugged it in only a minute after it shut off concerns me. Why is that? Is there something potentially wrong with my MBP? FYI, I tried multiple outlets and it always showed up with a green light. I guess I still am confused about a couple of things.first, when I did plug my computer in - which was like a minute after it suddenly shut off - the light on the MBP was green, not amber which was confusing since obviously it had no battery. Stop doing that and you will never go through something like this again until the battery finally stops working from age, number of recharge cycles or the abusive treatment you have subjected it to. BLUESTACKS OLD VERSION 10.6.8 + 3+ + + MACOnly thing wrong with your Mac is that you abuse the battery. I have never run my battery down to the point the system would power off so I've never been through this personally but I suspect the charging circuit needs time to check the state of the battery and the state of the charger before it starts to put power, starts recharging, the battery. ![]() Whenever I connect my AC adapter after using the battery it always shows Green for a few moments before turning amber showing that it is charging the battery. When that happens the battery needs time to recover from such a traumatic event, it doesn't like being drained all the way and needs time to power up the cells inside of it. When it Suddenly Shut Off it had Depleted all power in the battery. ![]()
