OS X :: Airport Card Performance - Plugged In Vs. Running On Battery?
Feb 11, 2010
I was running some networking performance tests the other day for some research project. Essentially I have 7 computers on a LAN that is not connected to the Internet - all computers are connecting wirelessly. I have one computer function as a server and it multicasts pings to the other 6 computers at a constant rate (e.g. sends a packet every 2 seconds).I noticed some odd behavior - 4 computers received the packets in about the right time intervals (every 2 seconds), but 2 would get packets at intervals of roughly .92 seconds and 1.12 seconds consistently. I realized that these 2 computers were running on battery and not plugged in. Plugging in all computers got all the computers receiving packets at the same time.

I have a G3 iBook I've put together from spares just as a project. Everything works fine and will connect to the internet over the ethernet cable.As soon as I plug an Airport card in it refuses to boot, it won't even try so it seems to be a hardware issue.Is it possibly a dodgy Airport card or something else?It's a 2001, 600Mhz, Dual USB, white 12" iBook.

I am not sure if it only my macbook, but I notice a slight performance drop when I run on the battery v the AC. I notice that my application load slower, folders open slower and expose and spaces response is also slow as well.

I have a MacBook, with OSX 10.4.11. It uses an AirPort Extreme (0x168C, 0x86) and it connects to a Linksys router which is attached to my cable modem in the basement. Approx. 4 days ago I started noticing that the signal strength would vary, and then drop off all together. I have reconfigured my router, downloaded the new firmware for it, and been online chatting with Linksys techs all day. We have had no problems for months with this router, or with signal strength. My wife brought her MacBookPro home this evening to see if her machine would connect to our wireless network. Fired it up and no problem. Her machine, using the same airport card in it, had no problem with signal strength.

Earlier today, maybe around 3PM, I was using my laptop, and it was charging and it was maybe around 60% battety life when out of no where it just shut off and even the light on my charger went out. When I turned it back on, the fan was running and there was an X over the battery icon. I've tried turning it off and on, and leaving it alone for a few hours, to see if it would resolve the problem but it didn't. Â It is currently 9:52PM, I'm still experiencing these problems and I'm using the exact laptop to type this, but I don't know how much battery life is left.Â

I have a Dual 2GHz PowerPC G5 running OSX 10.5.8 and want to have wireless capability, if possible. There does not appear to be a dedicated slot for an Airport Extreme card on the motherboard, so I'm wondering if there's a card that would work in one of the spare PCI slots?

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.
I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.

Apple Macbook Air late 2010, has been giving me poor battery performance even after replacing the battery under warranty. I am unable to find a solution, even the local apple service provider seems confused. Should I go for a replacement?My Macbook Air runs on the OSX 10.7.3 with all updates as on date. I use only softwares such as Microsoft Office for mac, Safari, Mail, iChat, iTunes regularly.

I've been told that I should replace its battery since it's been damaged. I haven't had the time or the money yet to buy a new one, and right now, I really need to use it.

I just bought the new MBP 13" 'cause I'm gonna need it for college, but since I'll also use it as "personal computer", for web browsing, playing music and movies, I'll probably have to charge every day. My question is: if I got home and my MBP is dead, I plug it in and use it, when the battery is fully charged, I have to unplug it or I can use it for the night (still plugged in) and just unplug it the next day for school?
Is it somehow harmful to my battery life? And by the way, I've read that "discharge the battery" means just use at least until the 50%, is that right? So if I charge it just when it's about 40%, I just need to recalibrate once a month, and that's all fine, right?

My wife and I always leave our MBP plugged up when we are near a charger. This morning the MBP had been plugged up all night, but the battery was dead. I noticed the light was out on the charger so I went to take it out, but when I touched it it turned red indicating that it was now charging. It turns out it is very finicky and randomly stops charging. Anybody else had problems with their charger? It will be Thursday before I have a chance to get to the Apple store.

I bought my MacBook Pro 13.3" 5 months ago (according to Coconut Battery) and the battery-loadcycle is already at 51 and 89% battery capacity. Anyway I wanted to know, if I keep my Mac plugged in on the charger will the battery-loadcycles decrease?

I bought my macbook exactly two weeks ago (tomorrow) and I'm already starting to have problems. My battery is currently at 10% when not plugged in but then when I plug it in it won't charge. What is wrong with it?

Haven't found anything relevant on this. Basically my 2010 15" MBP just emptied its battery and is almost fully charged now. All this while it was plugged into electricity. Why?

I recently bought a new battery for my ibook G4 and thought that it would solve the issues I was having with my battery. When I went to plug in the power adapter, the battery icon does not change to show that it's charging, so I borrowed a friend's because I thought I needed a new adapter, but it's still doing the same thing. So I've ruled out that it's not the battery or the adapter.

i very rarely use my MacBookPro away from home (scared of loosing it, LOL) almost all the time it is plugged into the mains 24/7, i just shut the lid when i am not using it. It is about 12 months old, but i notice that the battery meter never goes above 96%, does this mean the battery is on the way out and is going to get progressively worse ?I suppose it means the battery isnt going to last anywhere near 6 or 7 hours if i did unplug it from the mains?Â

my macbook will not start unless its plugged in to a power source. if you unplug it while running, instead of switching to battery power, it shuts off. the battery is currently at 53%, so i do not know why it will not run on the battery.

How certain are we that (physical?) interference between the airport card/wifi and the graphics card can be cured with a download, and not actual hardware fix/repair? I mean, I know technology is advancing rapidly, but I'm not sure I can believe that a download can solve the issue that the 4850s are experiencing.

for some reason my powerbook battery charge slowly goes down even while it's plugged in. The power light is green as if it's fully charged but it goes down about 1% every day and then if i unplug it and plug it back in then it starts to charge, goes up to 100% like it should and then starts all over again. It never used to do this so i don't know why it's doing it now.
It started happening around the time apple had that huge recall so then i got it replaced but it still does it so it can't be the batteries fault (at least it doesn't seem likely)

I just noticed that my when I got my macbook plugged in, it's not charging. The icon is the one you got when it's plugged in (with the little fork-shaped thing in the middle), but instead of it saying 'charging' like when the battery isn't full, or 'charged', when it is, it just says 'Not Charging'. It's like it can see the magsafe connector inside, but the juice isn't coming through to the battery, even though the computer itself is powered by the charger since when I click on the power symbol I get 'Power source: Power adapter'.
Also, the magsafe connector itself isn't lit. It used to be green for a bit, but a much weaker green than normal, and before that it wasn't even lit--I've tried with three different wall outlets, one of which was outside my house where I usually use it (it was in a starbucks). Also, when I disconnected the magsafe to get a reading for the battery, it was only 1:35, even though the magsafe light was green (albeit a weak green). If it matters, I'm running 10.5.3. The macbook is still fairly new, bought mid-december, all updates current as I got it set to checking daily and install the minute I get the notice.

I have a brand new MacBook ( < 1 month old ). I usually leave it plugged in and sleeping on my desk, and open it up to use it. After about a day of this, it will still say the battery is fully charged, and the light on the MagSafe is green, but the batter display shows 99% (or 98%, 97%, 96%). If I unplug it and use it for a bit, and the plug it in again, the battery will charge back up to 100% (and then the whole process will begin again). I love my MacBook, and want to make sure this behavior is normal.

My aluminum unibody MacBook is plugged in to the power adapter and the light on the adapter is green. The battery status indicator says "Not Charging." What do I do?

I looked around and I find varying opinions. My laptop is mostly at home. Should I keep it plugged in when its full or should I let it drain? Please explain too.
Also, coconutBattery says I've used five cycles even though none of those were complete cycles. Is it just problems with the software or does it really count as a complete cycle?

I've heard conflicting reports that leaving the laptop plugged lowers the battery life and that it is not true since it stops charging the battery. So is it bad to leave it plugged in all the time?

About a month ago I bought one of the new Macbook Pros, a 15 inch i7 version with highres matte screen.This morning I went to turn on my computer and I thought I had turned it off last night, but it turns out that I hadn't, so when I hit the start button it woke up and then promptly shut off. I haven't been able to get it to turn on since. Absolutely nothing happens when I push the start button, whether I have it plugged into battery power or not.

So today I was using my MBP that I got about a week ago and all of a sudden I got a low battery message. My MBP was plugged in at the time, and had been plugged in for about the last two days. AC adapter was plugged in and very hot i might add. MagSafe never got disconnected. After I clicked ok on the low battery message my MBP just started charging like I'd been using it on battery power and just plugged it in. I know there was no power outage or anything like that, all my computer stuff is plugged in to a UPS that beeps if it looses power and switches to the UPS battery power. I shut my MBP down when I went to work and when I came back it took a good min before it made the powering on noise and the apple appeared. I checked my battery health and capacity through the system profiler and the condition is normal and it has 7 cycles on it.

This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.
Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.
What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep)Â to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.
I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.
Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.

I play a game called League of Legends which is fairly computer intensive. While playing, my battery continues to discharge continuously even though I have it plugged into the wall. I can usually get 3-4 games in before I have to stop and let the battery recharge. I have already decreased the screen brightness to half, turned off the keyboard back-light, and made sure that bluetooth was off yet the issue persists. I have noticed that the light on the charger seems to change colors often. It will cycle from green to orange to off then back to green again etc.
I have an early 2012 15" Macbook Pro with the latest version of Mavericks OS.
