MacBook Pro :: Afraid To Leave Plugged In - Power Supply Melted
Jan 3, 2009
This probably seems a bit ridiculous, but after having my first power supply melt and short out on me I've been completely paranoid of this happening again. My first power supply was one of the older models from 2006. I then got it replaced by one of the newer smaller models. After about a half a year it started twisting around on the inside of the cable which got me worried. The apple store wouldn't replace it unless it was melted so I called Apple and got a new one.
I've had the newer one for about a year and the cable seems to be wrapping around itself on the inside again. There doesn't appear to be a place where it's melting or breaking. I take care to not wrap it too tightly. Using it as a desktop replacement I'd like to not have to worry about leaving it plugged in when I'm gone. I find it crazy that this is even an issue but after having the first one melt right in front of me I find it hard to trust. Are the newer power supplies any better?
So I just got hold of a few of these new battery chargers from Apple and I'm just wondering if these are meant to stay plugged in the wall, even after the green light goes off. Does the light going off mean that the batteries will no longer draw power from the power outlet and that it is safe to assume power will continue to be consumed? Or is it preferred that I plug and unplug the charger only when needed to avoid any, unnecessary, extra power consumption?
I have a PowerMac G5 with the first motherboard that is out of order, and another PowerMac
G5 Late 2005
with 2x2.0GHZ
Mounting the powersupply from the 2004 on the 2005 is the powersuply compatible or not?
EDIT: I looked on Mactracker and compared the two: Max Watts in the first is 604W and 450W on the late 2005. I want to put a powersuply from a G5 2004 (604W ) on a G5 2005 that had a 450W powersuply is this possible ?
So the power cord coming out of the AC adapter to the Magsafe melted and almost started a fire. There is about an inch selection where all I can see now is the metal wiring underneith, all the insulation is off. Is this covered under AppleCare? Since it was smoking and almost caused a fire, would this have harmed my MacBook Pro? I'm lucky that when I returned home nothing was damaged. How do I document this? What's protocol on issues such as this? This has never happened to me before.
Of course i'll unplug it 2-3 times a month and run the battery down to condition it, but other than that, is it bad to leave it plugged in 24/7, including when not using it and it's turned off?
I know it's okay to leave it plugged in 24/7 as long as I complete at least one battery cycle a month, but should I unplug it when i turn it off, or does it matter?
I have a late 2009 macbook pro unibody 15" and I hardly use the optical drive, in fact that startup whine is really annoying, would it be harmful if I just removed the drive completly and not leave anything plugged in?
I just got my mac about a week ago. I'm currently arguing with my grandmother over whether it's better to leave the MBP plugged into the adapter all the time or let it drain the battery.
My 2*1.8Mhz G5 tower (second version) shutdown two day ago and refuses to turn up again. I have absolutely no sign of life, not even the external white led or the internal red one. I'm trying to figure out whether it is the power supply of the start button which cause the problem.
Is it possible to test a G5 power supply like an ATX power supply, by connecting two pins which would make the fans start ?
I have an 8GB USB pen drive, formatted to Mac OS Extended (Journalled). I use it for backing up text documents (8GB goes a long way).
Is it ok to leave the drive permanently plugged into my iMac? I don't know what the life of these devices is supposed to be, so am I risking damage/failure by leaving it in?
Is there a way for me to leave a headphone extender cable plugged into the back of my iMac and have the external speakers play until I plug in headphones?
Anyone know where I can buy an extra AC cable for the MagSafe 85W power supply that came with my late 08 MBP? I'd like an extra cable and I'm not interested in ponying up the dough for the entire power supply. I checked the Apple Store and Macmall, but haven't found anything as of yet.
I made this a new topic because I think it is important enough to do so. Probably most of those that originally complained about this have moved on to the new MacPro but I am sure there are still enough G5 owners out there that still have concerns about this topic.
A clean install of Leopard eliminates the infamous power supply beeping
Its amazing, my G5 is like a new machine; no more of the annoying power supply beep; although, I learned to live with it after a while and didn't even notice it. However, the silence is now very noticeable.
At the beginning of the year my power supply died and Apple changed both of them. 4 months later, happened again. Now, 4 months later, it is happening again!
The power supply is plugged into a power strip with other electronics as well. The power supply keeps the laptop alive but won't charge it. If you unplug it the battery drains like normal. No light on charger, other chargers charge the laptop.
Do I have dirty power at my house that keeps blowing it? Nothing else has been effected.
Can a computer effect the charger? Please help! Still have 6 mos of applecare, but am tired of this. Would like to find solution.
I hav" a "late 2004" G5 2.0 dual processor. To upgrade graphics card, I find many require a power supply splitter. Do I have a molex 4-pin connector? I can't see the location inside the box.
I've been experiencing the following problem with my late 2007 MacBook Pro: I can't use it on batteries. As soon as I disconnect power supply, it works for 10-15 minutes and switches off. Not sleeps, but suddenly turns off completely. The system battery indicator drops by about 10% (showing 85-90% battery charged), whereas 4 out of 5 LEDs are lit on the battery itself. After such a sunned switch-off, I'm not able to start again the laptop - it doesn't react on Power On button - like the battery wasn't inserted at all. Right after I plug on power supply back again, everything gets back to normal and I can use it normally, but still only if it's connected to the electricity.
I'm just wondering if anybody knows whether it is possible to obtain a replacement battery and power supply for such an old computer. My 17-inch MacBook Pro is about five years old, and the battery seems to be completely dead. It will not start up, will not take a charge, and cannot be used, whether plugged in or not. A multitester test suggests that the power supply no longer works either. My MacBook has one of the older-design power supplies, with the circular port, rather than the newer, magnetic, rectangular ones. I'm planning on getting a new MacBook in the near future, but I need to access some things that are saved on my old Mac's hard drive, if at all possible.
Power supply partially expired on my 2.3GHz G5. Have found a donor. Manual says remove logic board before power supply. But you could remove power supply with board in situ on older G5s...
June 5th to September 19th.....not too bad, considering the laptop has been on the road quite a bit.
I finally lost (seems so, at least ) that little semi-clear plastic cap shaped like a rectangle with rounded edges that covers/protects the connector of the MBP power supply when it's not connected to the computer (and being transported).....at least, that's what I used it for.
I did a quick search and couldn't find any relevant posts, so sorry in advance if this has been addressed.
Does Apple or someone else sell a replacement for such a dinky little thing.....although, frankly, I found it to be quite useful to protect the connector .
Starting this morning an X has appeared over my battery icon. When I click the icon is says no battery available. When I check the system profiler it says no battery installed. When I click the button on the battery all 6 lights turn on. I have read similar posts to this that say when they unplug the power supply the mac turns off in a few minutes, mine however will stay on the same amount of time as if the battery was charged. I'm surprised that this happened because I bought a new battery 3 months ago because the original one short circuited when my hard drive went last summer.
I had to have the power supply constantly plugged in if I was using the computer. I tried shutting down the computer, removing the battery and restarting and that worked. However when I shut down, unplugged the power supply and tried to restart, it did not turn on. I'm hoping there is a solution as I use my laptop on the road often and not being able to turn it on without the power supply is a real inconvenience.
When I try to power up my Macbook Pro with the AC wall power supply plugged in -it wil not power up -light blinks and I hear rapid 'beeping'. If I unplug the PS , it boots up but if I then plug in the PS, the Macbook will eventually freeze and I'll be prompted to power it down and restart.
Info: MacBook Pro, Mac OS X (10.6.8), Will not power up with AC Power Sup
I recently got a new macbook pro (thanks to Apple's great customer care/Customer Replacement Unit policy), and two days later, it got stuck under a moving chair, which peeled off the outer rubber insulation for the power supply cord. And a beautiful thing happened I used to notice that the magsafe power adapter would slip out when i was moving my macbook around from place to place a little bit too easily. Then I put 1 1/2 inches of electric tape about a centimeter away from the actual magsafe-macbook port, and the addition added just a little bit of resilience because of some sort of physics i can't explain. so if you want your magsafe to be a little bit stronger, but still pull out if you move it too hard, just add an inch of electrical tape to the end. works like a charm!
It has no doubt come to the attention of many that the Radeon 4870 requires two PCIe six-pin power taps off of the motherboard, which is exactly how many allots. Say we wanted to use a GeForce 8800GT and a 4870 at the same time, which would require a total of three PCIe six-pin power taps. What I've read on the forums here indicates that powering them would be possible, but what ways would work?
As far as I can see, I've got two options:
1) Split one of the 6-pin power taps with a Y-splitter, and use the resulting two taps for one card and the other tap for the other card.
2) Use one of the ODD 4-pin molex power taps, convert it to a 6-pin tap, run it down to the card. But I'm running two optical drives; would it be possible to split one of those power taps into two, then run one out converted to a 6-pin and into the card?
I don't know nearly enough about the motherboards and power sources to know which way would work - if any - and if there is any risk involved. I'm running an early '08 mac pro, but I'm curious if this would work in other models as well. Anybody know enough about the hardware to say?
i'm in desperate need of an APC backup power supply for my mac pro and acd. the old backup i've got (APC ES350) is not sufficient to power the mac pro and acd. i purchased the ES350 for my powerbook almost 7 years ago.
anyway, every time i have a power failure (it happens quite often), my entire system shuts down. which APC should i buy? i want to ensure that everything still runs for a good while so i can save everything before powering down completely.
There has been plenty of discussions in the past re: CPU, HDD and RAM temperature, but what about the power supply on the Mac Pro?
My 08' MP reports 70 degree Celsius while the 09' MP reports 35 degree Celsius, while both machines are reporting an Ambient temperature of 27 degree. Why such a discrepancy?
