Macbook must be on battery (no A/C) to access wireless?!?
I have a Macbook (1 year old) and I just got a new wireless router (Linksys). We also have a PC, Xbox 360, and wireless printer, all which work fine with the new router, no problems accessing the internet. Now I know this is gonna sound weird, but my Macbook only loads internet pages when the a/c adapter is unplugged the laptop is running on battery. If I plug in the A/C, (and I have tried diff outlets) then it still says connected but no longer loads any pages. I called the Linksys company and they said that it sounded like an issue with my Mac, and I even went to the Mac "Genius Bar" at the local store and they had no idea why that would happen (Im not even sure they believed me). The old router never had this problem, and I have never had any problems accessing any other wireless internet signals. What is going on with my computer? I do not wish to return the router unless I have to, and I have no intention of paying for tech support. Any other ideas welcome, and thanks for responding.

Want to reduce your MacBook temperature, remove the battery.
From http://xlr8yourmac.com/
Want to reduce your MacBook temperature, remove the battery.
When we were testing V0.5 of SpeedIt we discover a strange behavior, if we remove the battery of our MacBook the temperature drop because the maximum operational frequency of the CPU become reduce to 1.0 Ghz.
We were investigating more on this, and we found why this happen, the SMC subsystem when battery is not detected, activate the Thermal Trip indicator and the CPU get into Thermal Throttle, reducing the frequency to 1.0 Ghz and minimum voltage.
You will find this and other "hidden features" with the documentation of the upcomming version of SpeedIt.
We decided to published this in advance because a user "no-one" write about this matter on the forums. He is a good tester we'll liek to take him in account . More information on the forums.
Apple Mac Intel SMC Firmware Update
We have been testing the lasted firmware update and the conclusions are:
* The fans run at more revolutions always.
* The Temperature drop more or less between 5 to 10 ºC
* The voltage values of the CPU change.
* The MacBook is cooler but more noise.
* To get into sleep need a minimum of 5 seconds, after
you close your lid.
* Don't put in your bag until you hear that the fan
stop, some times the MacBook don't get into sleep.
More detailed report and data soon.

Williamyeah its pretty ridiculous that an individual pays all that money for a machine that Apple continually trumpet to be better than a PC machine and then it falls down at these niggly little turns.
Other machines, can run at full speed with battery of, no ?
Why is it ridiculous ?
If I use my unit for some hardcore music / video editing sessions, I will take it off the battery so Im not constantly charging / recharging the battery - is that ridiculous ?
Am I going to be pis%£% when my expensive machine, I paid mad dough for is going to perform like a snail as opposed to what it can really - YOU BET !
"Beeing a picky customer is a MUST in this case. I realy don`t understand the people who are trying to protect this company no matter what happens. You HAVE to remember that it is not a privilage for you that you own Mac. It is a privilage FOR Apple that you decided to spend big time money on their products. It is your DUTY to be picky and strict."

Automatically sleeping a MacBook Air prior to battery reaching zero..?
Hi, does anyone know if there is a way to automatically 'sleep' a MacBook Air before the battery runs out?
I'm usually pretty good at plugging it back into the mains before it 'dies' but twice recently I have missed the warning for a low battery and it has 'died'.
There must be a setting or an app out there that will 'sleep' the laptop when the battery gets to a specified battery percentage or time remaining.
Btw, I have a late 2010 13" MacBook Air running Snow Leopard.Tried hibernatemode to 25 and still not helpful at all.
Battery drained 8% after 10 hours of sleep while mode 25 should put my macbook air into deep sleep and consume very minimal power.

Macbook pro mid 2011 battery lasting only 3 hours
How can I get my brand new Macbook pro mid 2011 battery to last longer, now it's lasting only 3 hours.
Do not believe the advertised specs from any manufacturer regarding battery life. In the real world expect about 60% to 70% of those figures. Battery life is influenced by many factors, Among these are display brightness, the number and type of applications you are running, if the optical drive is used, external devices that may be attached etc.
3 hours seems a bit low but not necessarily out of line. Go to SYSTEM PROFILER>POWER and see what it says by 'Condition'. If it is other than 'normal' you may have battery issues (Explanations then can be found in FINDER>HELP).

Macbook air energy usage - battery runs down whilst sleeping
I have a July 2013 Macbook Air and the battery seems to be running down quickly (more so while it is sleeping, the usage when awake seems to go down at expected rate).
I have taken it to apple genius bar who said the battery was fine and did a fresh install of 10.9.2 (I then restored my time machine backup). They ran a diagnostic and said battery was fine.
There are no big active processes under activity monitor and power nap functionalies are disabled.
The battery runs down over the course of one day if asleep and just now it dropped by 10% in an hour while asleep (closing the lid or going to apple and then sleep makes no difference).
It did seem to start suspicously around the time I upgraded to Mavericks so I feel it's a software issue....
Any ideas?!
Thanks so much
AlexisTami ...
I turned off any automatic updating, stopped Sophos Antivirus from on-demand scanning.
Regardless of turning off updating ..... a/v software on Mac can cause a litany of problems.
Uninstall the Sophos a/v software > Removing Sophos Anti-Virus for Mac OS
Then restart your Mac to see if it makes a difference. -
My macbook pro has service battery, what could happen if i upgrade the ram to 8gb
My macbook pro has service battery, what could happen if i upgrade the ram to 8gb
"Service Battery" means just that - you need to make an appointment with your local Apple Store or AASP and have the battery checked out and, likely, replaced.
If you upgrade to 8GB it will have no effect on the battery. 8GB is sort of the minimum that I would shoot for.

MacBook Pro late 2011 Battery Performance drop dramatically
MacBook Pro late 2011 Battery Performance drop dramatically
9 months 94 cycles and its health is now at 89%Does the system still run off the battery only? Does it run for a few hours off the battery only? Then No it is not defective and no Apple will do nothing for you and No Applecare does not cover Consumable items which the battery is one of those.
The only time Apple MAY, and that is BIG MAY, replace the battery is within the first year and only if Apple Deems the battery to be defective. Fat chance of that as long as the system runs off the battery for any length of time. -

macbook pro late 2010 battery at 24 cycles for 15 weeks computer and capacity is already 93%, anything wrong?
How many cycles depends on how often you drain the battery down low and then recharge it to maximum, ideally use it a little less on battery and a bit more on mains and the cycle count will slow down. Every couple of months you need to re-calibrate the Battery for best long term results.

Kernal_task is taking up 300% CPU on my macbook pro while on battery
Kernal_task is taking up 300% CPU on my macbook pro while on battery, but goes back to normal while it's plugged into power source. Battery life is still normal. Any suggestions on how to fix this?
I just received my MBP Retina yesterday. I have not installed anything and the system is running so slow that when I type the text on the display is lagging behind my typing. Scrolling, app switching, etc. are all either choppy or I have to wait. Activity monitor shows kernal_task %CPU jumping between 500% to over 600% with 83 threads and about 675MB real memory. The fan is on continously, does not matter if it's plugged in or on the battery. NOT A GOOD FIRST TIME EXPERIENCE FOR ME.

2008 MacBook freezing only when battery is attached
My 2008 black MacBook freezes when the battery is attached. If it is removed and ran on only AC power that machine works just fine. I have two of the exact same MacBooks (black, 2008) and have tried swapping batteries. According to system profiler they both are just fine. It seems to happen even if the machine isnt moved. The freezing is a hard freeze, that is, i cannot move my mouse or type and everything is just still. I have heard that some kind of ribbon wire could be the problem and people have said that putting a piece of paper on/around it can temporarily solve the problem. I am unsure of how to do this and am not even totally sure if this is whats wrong. Does anyone know of anywhere i can find good instructions for this? Will apple fix the problem? for free?
I have tried reseting the PRAM and SMC, both do not work. I have also erased the hard drive and reinstalled a fresh copy of snow leopard (i lost installation disc 2 of my original OS X cds, so apple told me to buy a new copy...over the phone that is). At any rate, the installation worked just fine and nothing has been installed or modified since. I really would like to fix this ASAP because I intend to give it to my girlfriend for our anniversary in a few days.
Please let me know if you have any input
thanks
BrandonFirst, try this:
1. Shut down your MB
2. Have ONLY the battery in it.
3. Power your MB up & immediately take it into Safe Mode (after the startup chime, hold down one of the Shift keys until the login screens shows up. Let go of Shift. Log in. Let it finish booting. At the Desktop, do a few ordinary things on your MB (not all programs will function in SafeMode though).
4. Report back here whether your MB freezes on battery-only power while it's in Safe Mode.
Second, download & install the iStat Menu utility.
After installing it, make notes of the MB's internal temperatures, particularly the 3 battery sensor temperatures when A) It's powered by only the adapter and then after a cooling down period, B) It's powered by only the battery. The Battery Temperature reading in iStat should show right around 85-90 degrees.
Here's a screenshot of my own iStat, with the mouse arrow pointing at my MB's current battery temperature:
Also, need some answers to these Q's:
1. What model is your MB?
Apple.com: "How to identify MacBook models"
EveryMac.com: "Lookup Mac Specs By Serial Number, Order, Model & EMC Number, Model ID"
2. What version of OSX are you running in your MB?
3. Did the frequency of the battery-only freezup problem develp slowly over time, freezing only every once in a while until now your MB freezes quite often, or did the problem just show up overnite -- yesterday, fine; today, freezing with only the battery in it?
4. Did you do anything major as far as changes to your MB are concerned, or did anything happen to it? (dropped, keyboard spill, etc)
This is an important one:
5. If you were to start your Macbook up in the morning on battery only after it being shut down all night, and the MB is being used normally, how long in minutes does it take, on average, for the first freezeup to occur?
6. When it is powered by battery only, and absolutely nothing has been done on it for quite a while after it's been turned on, & it's just sitting there with the screen open & the screensaver is running or the display is in sleep, does it freeze up?
7. Compare the temperatures of the bottom of your MB between 15-20 minutes of Power Adapter only use, and 15-20 minutes of Battery only use, with a cooling down period in between the two tests. Is there a huge difference in the two temperatures, or not much difference?
We'll get it.......
But I & other helpers who read your post just need more info from you before anyone can go any further with this.
