Hardware :: MacBook Pro Battery Percentage Rate
Oct 25, 2009
For the last few days I've been worrying about my battery, I know it's silly and everything, but it's supposed to have 7 hours. It will go for a good 5 hours, sometimes more than that. But the percentage rate seems to be going down quite quickly. e.g half an hour ago it was at 73%, now at 62%. The battery time also changes quickly, from 6 hours 42, to 2hrs 32, back up to 4hours, etc. I have checked the condition on Coconut Battery and it's at 100%.

My MacBook shuts down on random percentages when used on battery power. I can only use it for FIVE minutes before it shuts down. And as I said, it shuts down before the battery runs down to 0%.

When I plug my charger into my macbook pro it says "not charging" where the percentage is in the top right corner. The light on the bit that's plugged into the macbook pro goes green then orange. However the percentage of battery seems to be going up, but the little battery icon has the energy bolt sign and not the charging one.

I have a Rev B, 1.86 128GB SS. It is good except a little weak on battery and heat is still there for anything remotely intensive so my question is: How do you rate battery life of new 13 MBA? My Rev B gets roughly 2 hours watching a HD show from CBS, or 4.5 hours (best case) doing non flash surfing or anything non intensive work, watching photos, writing in word etc. Heat is there if I watch videos, like the example above, routinely around 70-74 watching a video show over the internet. RPM for fan 2500-3000 at that temp. How is the heat of the new one? (I tried one in the Apple store and it bare felt warm underneath while watching an episode on [URL]). My other finding is that the new one felt a little more "solid", cant point to anything specific but a general feel when closing and opening it. Btw, I still run Leopard since I felt that I lost battery time under snow leopard and that it was also slightly warmer under Snow Leopard. Any other difference you have noticed in the new MBA?

So I have a late 2008 MBP and the battery is draining way faster than it should. Coconut battery says that my battery capacity is at 93% and it only has 73 cycles but the battery has only been lasting 3 hours at best with a full charge, but most typically, it only lasts 2 hours while using the 9400m GPU and at idle. I have reset the battery per apple's instructions 2 times now and I have reset the SMC multiple times. this is what the system profiler says about my power capacity and consumption:
Model Information:
Serial Number:6N839TV313EB
Manufacturer:SMP
Device name:bq20z951
Pack Lot Code:0000
PCB Lot Code:0000
Firmware Version:002a
Hardware Revision:000a
Cell Revision:0100
Charge Information:
Charge remaining (mAh):3522
Fully charged:No
Charging:No
Full charge capacity (mAh):4226
Health Information:
Cycle count:72
Condition:Normal
Battery Installed:Yes
Amperage (mA):-1449
Voltage (mV):11830
This all happened out of nowhere one day, I used to get a solid 5 hours on each charge a month ago and now this.

For some reason, I am having trouble uploading to tiny pic, image shack, photbucket etc! The % bar would appear on photobucket and just sit there and hang never uploading anything. Same goes for the other websites.

I've been following this forum for quite some time after I first got an iPod touch and, recently, an MBP "17.Now, after I did some searches on the internet and couldn't find the answer, Im asking here:My MBP comes with a built-in draft-n wireless card. I bought a draft-n wireless router just for the purpose of utilizing greater wi-fi speeds, but there is one thing I noticed:when I boot MacOS and connect to the wireless network it shows me, tat the transmit rate of the network is 130 (Mbps I presume), on the other hand, when I boot to Windows (via Bootcamp) and connect to the same network - it shows a network speed of 280 Mbps. In both cases the transfer speed are relatively close and go up to 8-9 Megabytes per second.

I play a lot of video games on the internet but my connection is not great around 512kbs. I am trying to reduce the sample rate of the microphone from 44k to 22k to use less bandwith when I talk to other players. I always break up when I talk. There is no option to do that in the sound settings. Is there a way to do it? I have a macbook pro 15' 2.5 ghz intel 2 core duo. With 3gb of Ram.

I have a 2.66 quad core 2009 Mac Pro. Running 10.6.2. I see weird behavior in the Activity Monitor. The "% idle" number jumps from 49% to 61% to 99% (but usually stays around 49%), when I'm actually 99% idle. The "% user" and "% system" just don't add up to "% idle." Does anyone else see this? I'm wondering if it has anything to do with the RAM I just installed, or if this is a coincidence.

'm using my MBA to watch movies on my fullhd TV.
I use the dvi interface to connect to it at 1920 x 1080.
The problem is about the frame rate that after 10 / 15 minutes of flawless palying, drops consistently. I've tried VLC and QT with Perian but the problem is the same.
The only way I can use it, is activate the mirroring function and keep the resolution to 1280 x 800.
The strange fact is that the cpu is quite free and the temperature never goes more than 62 celsius.
I think that the problem could be an overheting of the video adapter. The fan, while I watch movies, is stick to 6200 rpm.

I will be running MS Excel, preview, firefox, and activity monitor. All of a sudden my Activity monitor says that there is about % User of 50% and the fan will start running. I cannot find what program is making it run this high. I quit every program and it gets stuck on this until I restart the computer. I have done this about 3 times and it always comes back. None of the programs are registering high CPU usage. My last computer had an overheating problem where the fan was always on and that was part of the reason I switched to Macs - really hoping that issues doesn't follow me from Windows to Mac.

Macbook Air won't shut down and often the fan runs at a very high rate without stopping. I do notice it seems to get hot on the bottom more than in the past. Any suggestions as to what I should do, I can't keep holding the power button down to shut off the computer.

Is there a way to find an Ethernet Transmit Rate? I'm running a Mid 2010 Macbook Pro. For example, to find the wifi transmit rate, I know I can hold down OPTION and click on the wifi icon in the menu bar and view various wifi specs in the pane that drops down. I also know how to look up LINK SPEED via Network Utility > info > ethernet/wifi, etc....Â
Is there even such a thing as an ethernet transmit rate, or am I creating my own vocabulary?

I have a new, week 7, 27" iMac with 2.8 quad core CPU. Activity Monitor shows the "% idle" number jumping anywhere from 49% to 99% (but usually stays around 49%), when I'm actually 99% idle. The "% user" and "% system" numbers are less than 1% when the computer is idle. They just don't add up to 100%. Does anyone else see this? The left top of the computer is hotter than any computer I have had before. This is the third computer that Apple has sent with this problem. Apple Care just says to send it back.

I really thought apple would have a much lower rate. My friend thinks this can be attributed to the white macbook line. They are apple's best seller and they are plagued with issues of cracking, and screen issues. what do you think?

After migrating to Mac last year, I've also begun my migration to iWork from Office. I now have one problem that I can't seem to resolve. I am trying to paste chemical structures from Chemdraw into my slides, however each item I paste have different size. However, my chemical compounds are a specific size that I need to keep constant.Is there a way for me to alter the size of items i'd like to post by altering the percentages? In the past, I'd alter the item's properties in powerpoint and change the item's size percentage.

Has anyone come across any Firewire memory keys? (Similar to the USB Keys we have now days). Firewire has a much higher transfer rate than USB 2.0, so I was wondering if any company made the firewire memory keys. I did a quick google search but didn't come up with anything recent. All the articles I read were from years ago.

I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!

I started noticing a few months ago that CDs I have been importing no longer display "256 (VBR)" anymore even though I have my import settings set to iTunes Plus. I tried using a custom setting that is exactly the same thing I went through custom->stereo bit rate of 256->and checked the box for VBR. The same thing happens with both. Initially "256 (VBR)" is displayed in the Bit Rate View; however, after I play the track or if I edit any of the tags it immediately switches it to 256 and no more (VBR) listed after it. Is anyone else having this issue? I thought with the last few iTunes updates that maybe this would resolve but it hasn't.

Having enormous troubles with using Wifi on my MP. I've had this before and it's a PITA.The transmit rate just drops to 1 (it should be up in the 90s shouldn't it?) Is there any known fix? I'm using Leopard. Should I upgrade to Snow Leopard? Does this solve it?
