MacBook Pro :: Works Faster If Plugged To Power Otherwise Slow Down
May 30, 2012
I have a 13 inch Macbook Pro that sometimes it works fine, but it always suddenly slows down and doesn't fix itself, but the moment I plug it into the electrical power it normalizes itself and works fast without a problem.
Like two months ago, my MBP started to work really slow when not plugged to electricity, but as soon as I plug it in, my MBP works perfectly. I already sent it to apple for they to fix it, but they solved other issued except for that one. Please, any idea what could it be.
Safari has been running slow for me lately. There is no problem with my internet connection. I have firefox too and it works blazing fast. So, why does safari run really slow?
I've been suffering of slow speed on my macbook pro, and this happens when I unplug it from power and just let the battery works itself, then the % CPU usage increases dramatically to 330%Â and the laptop becomes very very slow, what should I do? Because if my macbook is off-power, it doesn't work properly, so what is the point to own a portable computer?
Problem: Once shut off, my Macbook pro won't turn on by pressing the power button. It is as if I must jump start the computer using the power cord. What is interesting is that if I push the power button (without the power cord plugged in) the macbook won't turn on, then, when I plug the power cord in, the computer magically turns on without my PRESSING the power button. It is as if the computer knows it has been told to turn on but is waiting for more electricity.Â
When the computer is on, The power button also doesn't react when I press it. As recall, on macs, pressing the power button quickly creates a pop up menu that asks if:Â
a. you want to shut down the computer b. restart the computer c. put the computer to sleepÂ
This computer will shut off if I hold the power button down but does not give me the pop up options.Â
Battery appears to be in good health. Though it has been through 780 cycles. Coconut battery says that the battery is fine. This Macbook Pro's Sd slot stopped working as well.Â
I just bought a macbook air, and i am wondering, if i can use my macbook air plugged in to the charger at all times using at home? or i have to charge it , then empty the battery, and charge it again then remove the plug and empty the battery again and again? Cant i just use the macbook air plugged in when i am home? Will that affect the battery life of my MBA?Â
I bought my girlfriend a MacBook Air and 24" LED Cinema display, and the MBA works great when it's on its own. However, when she plugs in the 24" and runs the MBA in clamshell mode, she gets beachballs even when trying to print, open folders...the whole system seems to slow down. It's the Rev B MBA with the 1.6Ghz C2D, so I can't imagine it's the 9400m, she doesn't have a full hard drive...I just can't think of what is causing the system to slow to a crawl like that?
I have a late Macbook Pro 13''I using it at home about 10 hours a day. so it's allways plugged in to AC Power while I'm using it, and when I'm not using, I disconect it from Power.I want to know if this damage my battery OR not? Or should I running my Macbook on Battery? and recharge it (and cycle monthly ... )
I think the title pretty much explains it all. I'm wondering if there's any harm that would come from leaving the power adapter plugged in all the time, but without the MacBook connected some of the time. I'm a college student, and with the way I have my desk set up, I can't really take the power adapter with me everywhere I go. So yeah, I was wondering if there was any harm that would come from it.
Will this have done any damage? The macbook pro was not powered up, but I had the the mac ac adapter plugged into a power strip with the magsafe adapter connected to the laptop, since I keep it plugged into ac all the time at my desk. The power strip was on while the power outage happened. I had the 3 prong extender cord of the magsafe plugged into the power strip. The power outage was due to a problem with some power lines in my neighborhood, not from a surge of overuse of fuses in my home, so my whole block was without power for about 2 hours.I did notice the power strip has always had 2 lights on; one red, not protected, & one green, grounded. The outlets in my room are only 2 prong, so I have a 2 to 3 prong adapter plugged into the wall that the power strip plugs into. I know this is not the best, but my house is a 1950's era house, & I do not have the knowledge & have safety concerns about trying to convert my bedroom outlets to 3 prong. I hope this did not cause damage to my macbook pro. Is there anything I need to do before powering the mac on to use the next time? besides convert my 2 prong outlet to 3 prong? will there be any static charge? this outage happened on a very hot & dry day in my area.
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?
My MacBook Pro power adapter lights up orange even though it is not plugged into a device. When I do plug it into my laptop it remains the same and does not charge. Due to this my laptop is now dead.
I really love the magsafe connection. It's very easy and handy.The fact that it works with magnetism is nice. Especially when you accidentally trip over the wire. It will release itself from the computer.But now with the macbook air 11.6" the weight is so low that you will pull the computer with it when you trip over the wire.
My MBP13 (Late 2011) with Lion 10.7.4 suddenly stopped charging...battery level continued to come down when power adapetr is connected...I am able to check MagSafe is working fine in both of its ends..but the system is not charging and there is not LED on when I connect the adapter to system...tried all the possible ways to fix it including SMC reset,,(but i am not sure if SMC reset worked in this case!!).
It was working OK. I have put it aside for about 1 month during the holiday. Now, it can not be charged. It works on power adaper, the plug has bright green LED on, but always 0% battery. Looks like the power adapter is still working OK, battery issue?
When I unplugg my pc vid card 5770 i can boot to mac but when i plug it in the power port on motherboard i can only bootcamp to windows is this normal?kind of a hassle everytime i want to play games because i have to shut down then plug in vid card to crossfire
Just wondering, if I were to go for a higher specd Imac with a more powerful video card (thinking possibly the refurb with the 8800), would this be a significantly bigger energy drain, or does the card not kick in to full force unless a task requires it to do so?
I get this strange message every so often, sometimes more often than other times. It says:
USB port drawing too much power. The device that is plugged into it will be deactivated.
There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
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.
I had problems with Finder, it just crashed on me when I opened folders that had a bit more files. I have an 24" iMac with v10.5, 2.4 GHz Intel Core 2 Duo, 3GB 667 MHz DDR2 SDRAM. I bought it a year ago, add a month or so... So after I got all the glitches with Finder, I transported Applications, Documents, Music, Pictures and some other folders on my desktop to an external Hard Disk, when I finished with ERASE & INSTALL, Finder doesn't crash, but it's VERY VERY slow, for example, in my iTunes Music folder, I have about 560 folders, and when I click SELECT ALL(on the keyboard) it stops for maybe a minute or so, and then I try to copy them to a folder, when i try to drag them, it stops for 2 minutes or so... I haven't even copied much from the external Hard Disk. Except going back to Tiger, is there any other way, because my iMac is...not new, but not old enough to have those glitches... PLEASE HELP ME, this isn't the first time, this is actually my 3rd time doing a reinstall, 2 ARCHIVE AND INSTALL's and 1 ERASE AND INSTALL... what could it be?
each 10-20 sec it shows me this damn "Volleyball" and loads for about 10-15 sec. i can't do a thing :-/This is happening for about 3-4 days now.sometimes it works very well for about 3-5 minutes, but then it slows down again :-/working with skype, itunes, internet browser...nothing works fluent :/itunes stops playing songs while loading.
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?
Until recently, my MBA powered down in ~2 secs. It's now taking ~10 secs. It may be down to the O2 usb modem (huawei) that I used but I have already deleted it. I cannot see any residual files in Login Items. I have also run Onyx.
Just got a new iMac and when I use safari, my connection is VERY slow. I have my old imac and other NB's running on the same home network and they work very fast and work fine. my new imac seems to show the address it's going to but sits there for literally min's before it connects or if it connects.
Info: iMac, Mac OS X (10.7.4), 2,7ghz, 4gb, 1333 mhz, ddr3 4gb
