Power Mac G5 :: Which Battery Backup To Choose For My System
Oct 8, 2007
I 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.

I can't install Mac OS 9, because the page "Select a disk to install" is empty, so I can't choose a disk. The disk is OK and the Mac OS installer too. I am trying to install it because this is the last version that a Power Mac G3 supports.

PowerMac, Mac OS 9.2.x

Been a rough two weeks. I had the issue of my iMac not loading passed the grey screen. No keystrokes were working so I had to bring it in to get repaired. I was told some optic something cable had to be replaced.
Well, initially that didn't work but it just ended up taking forever too boot. 20 or 30 minutes. Now it is loading fine and Windows is also loading fine with bootcamp.
However, I can't get in to turn on my USB wireless adaptor for Sprint. I can open the system preferences and I can also go in to any other option without problems, but if I click "Network" it says Loading Network, then hangs up. I need to force quit and retry. Same results. Anyone know how to repair that? I have tried Disk Utility and it says no problems. Diskwarrior doesn't let me do much since I am booted to that drive.

My 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.

Just 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.

I 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?

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.

My screen suddenly went dark. I was connected and at 100%, however, now the battery is not charging. The system report says that there is no battery installed. I am hearing "white noise" also.

As 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?

I recently discovered my computer had died while it was sleeping. I tried charging it but am recieving the "Battery not charging, power source: power adapter" status.My power cord light is green, always. and the computer dies instantly when I remove the magsafe.
I've tried the "remove the battery, press the power button, plug in the magsafe" troubleshooting process, but it doesn't work.I've noticed that even with the battery out, the charger reads a green light.I've tried several outlets with the same results.Here are my battery statsÂ

The Apple one looks tempting as it comes with 6 batteries and 29€ isn't too much, plus, as usual, it looks brilliant. I looked at some 3rd party chargers as well ranging from 20€ to 40€. None of them was stunning or special by any means. Cheaper ones usually came with two or four batteries and some came without batteries. I don't really need it for else than Magic Mouse, occasionally for something else too.

I 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.

I've owned my Air for about 4 months now, and on the rare occasion that it sits unused for a few days, I always find that the clock has reset itself to something like 1-1-08. I'm guessing there's an internal battery to blame?

I 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?

I 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!

I have a G3 IBook 500 mhz with 2 usb ports. The clock and date don't stay set so I think I need to replace the back up battery. I am wondering how difficult this is to do on it. On my G3 Powerbook it was fairly simple.

I 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).

The 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.
