Power Mac G5 :: Which Battery Backup To Choose For My System
Oct 8, 2007I want to get a battery backup for my PowerMac G5 dual 1.8ghz PPC, but the numbers confuse me. the UPS selector tool on APC's website suggests I can get away with one that runs at 800VA.i dont need it to last long, I'm really just looking for something that will protect from surges, condition the power, and give me enough time to shut down in case of a power outage. I wouldnt need more than a few minutes, and I dont expect more than a few minutes power supply.

Mar 19, 2008My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.
View 10 Replies View RelatedOS X :: White Macbook Runs On AC Power (no Battery) But Not On Battery?
Apr 29, 2010Just wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.
MacBook Pro :: Battery Running On Reserve Battery Power
Jun 18, 2010I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles. Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?

MacBook Air :: "Proper" Battery Usage For New - Aka Power Supply Vs Battery?
Nov 29, 2010As I just bought a 13" MBA, I am still in my "babying" phase of the machine and want its battery power/capacity to last as long as possible. I have already done the battery calibration recommended by Apple (not even sure if its 'necessary' but I did it anyways), with charging, resting, draining, resting, and re-charging. But now I am worried about the battery cycles. Should I only plug my MBA in when the battery is close to being drained (aka use it on battery power for most of my usage?) or is it okay to drain the battery to like 80% remaining, charge, and then drain to 70% remaining, then charge again? Im not sure if Im making sense, but basically I don't want to be wasting these valuable cycles, as they seem to determine battery health and longevity. So what is the proper battery usage for the MBA, or is it basically use off power when you want and use on power supply when its available?

May 31, 2010I recentelly got a g4 powerbook titanium for a good price and aslo found a good battery for it online. I'm wondering if its better for battery life to use the powerbook on ac power when its available like when im at home or in starbucks and there is an outlet available or should i use it on battery alone unless the battery needs to be charged? I dont want to harm the powerbook or the battery but still want to get the longest life from the battery.

View 2 Replies View RelatedMacBook Pro :: 10 Min To Power Up When Battery Is Down?
Jul 29, 2010I have a mid-2007 MBP. Here is my issue...it's been more than a year that when I totally discharge my battery (meaning the MBP shuts down), when I connect it back to the charge it is taking abotu 10 minutes to power up again...it was not the case before and my wife's MB is working well....meaning when it is down, just connecting the charger the MB is back on within a sec.
I have changed my battery but it did not change anything, I called Apple and they recommended me to restore snow leopard...which I did...I still have the same issue.
Does anyone experience this? Any idea what is happening (HW or SW issue) and is there a potential fix?
Battery Won't Power MacBook
Jun 21, 2012I have just bought a second hand MacBook laptop and it has a wierd battery issue that can't seem to find mentioned anywhere.Initally all seemed fine, but then I noticed the battery wasn't charging and the battery menu reported no battery found, also the MagSafe plug had not light; some searching instructed me to reset the SMC which I did, and everything was fixed, I could runs the computer from the battery and the power lead charged the battery. But now (just a day later) the battery won't power the computer at all - the computer will only work if the power is connected - however the light is shown on the MagSafe plug and the battery is being changed, but if I disconnected the power lead, first I see the restar/sleep/shut down dialog that you see when pressing the power button, then shortly after the computer turns off, if the power if reconnected, it boots from scratch, so it wasn't asleep!

Apr 22, 2012I have got a macbook pro with 2.2 ghz AMD 6750 graphics card. Its around 8 months old. The battery used to last around 4 hours but recently I get around only 2 hours. I have tried to change settings in energy saver to improve battery life but its still the same. I ve noticed that when it shows AMD graphics in about my mac, it takes more battery life. So, I guess its using more battery at that time. Ive read it switches automatically depending on the task but is there anyway to change it in settings?Â
Also, how is it possible to get the best possible battery life? Should I keep charging and discharging it every now and then.? Currently I unplug the adapter as soon as it gets fully charged and the battery last for over 2 hours (surfing, listening to music, half an hour of video).

May 21, 2012The 2011 macbook pro with i7 processor will not power up or charge at all. The problem started after my battery ran out and the computer shut down. Since then, when I plug in the charger only the green light turns on. In addition the light on the base (in front of the keyboard) flashes. Nothing happens when I hit the power button. The charger still works on other laptops. To emphasize, the screen will not even light up. It sounds as if the computer is starting (for less than a second) before stopping, only to start again but that is purely speculative.

MacBook Pro :: Battery Calibration - Power Cord
Oct 12, 2010Well I just scored a 15 inch 2.4 from Bestbuy for 10% off. SOmebody just returned it having never even used it, but they had to discount it because it was opened. I love it love this thing!We did migration from our imac and everything came over. AmazingOne question about calibration. I charged it fully and let the power cord be in it for an extra 2 or so hours. I then used it unplugged until it basically shut off due to no power. Cant I just plug it in and let it charge all the way without letting it sit for 5 hours. Its not sleeping I dont think. It actually shut off suddenly as it was at zero percent. There is no power to it at all that I can tell. Will charging it now without leaving it unplugged for 5 hours ruin the calibration??
View 2 Replies View RelatedMacBook Pro :: Switches Itself Off / Was Running On Battery And Had 60% Power Available?
Dec 2, 2010I have a late 2007 MBP 15inch 2.33Ghz Core 2 Duo. I have had since new and no problems. Over this last week I have had the same issue a couple of times. The MBP just switches itself off. The first time it did it, it was running on battery (I was using Aperture) and had 60% power available. It would refuse to re-start until I connected it to the mains and then it ran fine.
Then it did the same thing overnight at some point. I had left it connected to the mains (as I always do at home), had shut the lid to put it into sleep mode. When I came back it was switched off. No-one had touched it whilst I was away but yet it had just turned itself off.The only thing that I noticed was that when I started it up both times the little light on the magsafe connecter kept flashing between orange and green. However when the computer booted into OS X both times it showed a reasonable amount of power in the battery.
PowerPC :: IBook Will Not Draw Power From Battery?
Aug 3, 2007I have an 14" iBook, 1.07 GHz and it won't use battery power. As soon as I unplug it it turns off. It worked fine until I opened it up and swapped in a DVD-RW and a new hard drive (the old one was failing). In the power section of system profiler it shows 98 load cycles and about a 75% remaining capacity. It may or may not be charging - I can't tell. The battery says it's fully charged at 95% and I have no way to drain it and see if it will recharge because the computer won't drink from the battery. I had another 14" iBook battery laying around that I thought worked, but now when I put it in this computer it just sits at 0% then eventually says the battery is dead (the menu icon shows an X through it).
