Not sure if problem is from battery/ power adapter

This morning I tried turning on my laptop, but nothing happened!!
I tried charging it, but the light is green (meaning it is fully charged). The battery indicator light only shows 1 light out of 5. Does this mean that the battery is dead???
Thanks!!!

The PMU reset is what was done for the Power PC Macs. The SMC reset which you linked to in your post is the correct one to do. They are the same type reset just different names for different Macs. It will not erase any data off your drive.

Please Help! My battery won't charge. Not sure if this is my battery or the charger causing the problem.

I recently came down to Costa Rica to do some work abroad and last week my battery display showed it wouldn't charge higher than 15%. I've kept the charger plugged in to avoid a total shut down and everytime I do unplug I lose power. I'm not sure if this is my battery or the charger that is faulty. I'm now at 8% power and freaking out as I have work to do and I'm nowhere near an apple store or certified repair shop. I can keep my charger plugged in but must find a solution. A new charger or battery can possibly be brought to me from San Jose but I must know asap to request the product.
Any help is SOOO greatly appreciated. THANK YOU.
Some Details on my computer...

Hi Riyanna. Do you have the mag safe power cord with you and will it turn on with it? With it plugged in you should be able to go to the top right screen menu and click on battery. It should say power source power adapter. It maybe grayed out , but that is ok. That means your power adapter is working. Then it will not hurt to run the SMC reset or pram reset. The other thing is if you are using an Aplle power supply there will be a green light showing on it.

Safari is giving me a missing plug in message when I try to view things like movie trailers. The trailers play on Firefox, so I'm not sure what's missing from Safari.

Safari is giving me a missing plug in message when I try to view things like movie trailers. The trailers play on Firefox, so I'm not sure what's missing from Safari. I have Safari 5.0.6 and Mac OS X 10.5.8.

I just noticed that it won't play some newsite videos anymore either. What plug in do I need to update (if that's the problem)?

Peep sounds when working from battery power

Hello
I bought a new HP DV6-1340 laptop
I hear some strange peep sound from the notebook hardware when its working from battery power.
When working from outlet power there is no peep sound from the hardware.
Maybe its because the battery is new or something there wrong ?
Thanks in advance for help

I solved it my self. It was OK (no buzz and fuzz) when it was plugged in (when the electicity line was down once and I was running on the UPS battery).....

When charging and using, ipad 2 is 100% battery, does ipad use the power from the power adapter or from the battery?

I have a quention, when i am charging and using my ipad 2 at the same time, if the battery of ipad is fully 100%, does ipad use the power to work from the power adapter only or from the battery only or both? Thanks!

YOu don't have to have your receipt. Apple should have a record of how long you've had the device. If you bought it in april 2012, then your 1 year warranty against manufacturer's defects is almost up. You should find your local apple store, make an appointment and take it in.

X200s - problems switching from mains power to battery - temporary freeze

Hi All,
Noticing a problem with a brand new x200s downgraded to Windows XP from Windows 7 (although never operated with Windows 7) where there is a temporary freeze when either connecting to mains power, or disconnecting from mains power. While it is not a proper freeze, as I can ALT+TAB between applications, I cannot actually do anything (close AP's, write emails etc). This lasts for up to 3 or 4 minutes, and then everything recovers - recovery happens to the extent that anything done during the freeze suddenly happens, like pressing the ThinkVantage Button, or right-clicking on a taskbar item etc.
I wonder if this is something to do with the Lenovo power management system - anyone got any ideas please?
Many thanks

Hi,
make sure, that you are using the latest version of Power Manger , power mangement driver . These two parts are basically responsible (when they are installed) for the power configuration.
Please let me know, what is the version of Power manager and power management dirver, that you are using.
Also based on you description, when all is working, when pressing ATL+TAB, then try to open Task manager with CTRL+Shift+ESC and check, what is taking the CPU and memory comsumption.
Once this will not show you anything, go to Windows Event log, maybe there you can find some hint.
Just to make sure, that I understand this corectly: You see this kind of behaviour, when you unplug or plug in the sytsem into AC ?
Cheers

Macbook airport problems linked to battery power?

I too have experienced the macbook/airport problem, specifically since 10.5.8 came back. When I upgraded to 10.5.8, it was so useless that I just reinstalled tiger. Then Snow leopard came out and I upgraded only to experience the same problem but not as severe.
I have just been able to pin/point the problem today (mainly because I just grew so frustrated and spent considerable time trying to figure out). I have tried all the other potential fixes posted on here to no avail (changes airport settings, replacing card, changing dynamic IP to manual, encryption etc).
This is what I have determined and was able to reproduce it:
When macbook is running on power (plugged in):
If battery power is below 60%, connection is spotty - the lower it is, the worst the problem.
If the battery power is above 60%, no problems at all, runs fast and no drops.
When macbook power is not plugged in and running on battery:
Below 60% almost useless
Above 60% spotty and worse as the battery drains
Can anyone else test this out? I've sent Apple an e-mail.

I've gone down to maybe 15% without any noticable difference in connection.

DV4 Battery Issue - Battery Charges; But Laptop Won't Run From Battery Power

Greetings,
I have a DV4, and let me tell you - I am so over this laptop. I have had it for over a year, and in that time, the backlight went out 6 months into owning it, the battery died just after the one year mark, and the webcam has been broken since I sent this computer back to HP to have the backlight issue resolved. I will never buy a new HP ever again.
Now, the battery I have replaced in my laptop charges - but, when I unplug the laptop from the wall, the battery power does NOT switch over. I have had this battery a total of two weeks - it was working fine until last night. Any ideas?
Thanks!

Hi, SoCal Cal. Take a good hard look at your battery contacts: both the ones on the battery itself and the "prongs" in the PB case that engage with the slotlike contacts on the battery. Are any of them significantly darkened/tarnished? Is there any debris or fluff on or in them? Clean out any foreign matter, then insert and remove the battery at least a dozen times in succession to see whether doing so will wear away any tarnish that may be impairing the necessary electrical connections. There's not really any easy, better way to clean the contacts, at least not the ones in the slots on the batttery itself. Then test again.
It sounds to me as though not all of the battery contacts are making good contact — though some of them obviously are, at least some of the time. Perhaps "working" the contacts this way will improve matters.
I really don't know what's going on with your machine; these are just shots in the dark.

From Battery power to running off the mains.

Hi guys
Just wondering - when I'm running my iBook off the battery and then decide to run it off the mains again, do I need to shutdown and then turn on the mains and then restart? Or can I just simply have it running off of the battery and then turn on the mains switch when I want to goto mains power?

You can just plug your iBook in whenever it needs to be charged. There's no need to restart/shutdown when switching from battery to power adapter.
Hope this helps,
-Ryan

I have a mac notebook and time capsule. I got a message that my startup disc is almost full. not sure where to go from here. if i delete files will they still be on the time capsule.

I have a Mac notebook and back up to time capsule. I Got a message that my statup disc is almost full and I need to delete files. Not sure which files it means and will i lose my files if they are saved on the time capsule.

Visit
The XLab FAQs and read the FAQ on freeing up space on the hard drive. Also see Freeing space on your Mac OS X startup disk.
About TM "Backup Drive is Full"
Alert TM only deletes older files if they have been deleted from the source and when TM needs space on the backup drive for a new incremental backup. Time Machine "thins" it's backups; hourly backups over 24 hours old, except the first of the day; those "daily" backups over 30 days old, except the first of the week. The weeklies are kept as long as there's room.
So, how long a backup file remains depends on how long it was on your Mac before being deleted, assuming you do at least one backup per day. If it was there for at least 24 hours, it will be kept for at least a month. If it was there for at least a week, it will be kept as long as there's room.
Note, that on a Time Capsule the sparsebundle grows in size as needed, but doesn't shrink. Thus, from the user's view of the TC it appears that no space has been freed, although there may be space in the sparsebundle.
Once TM has found it cannot free up enough space for a new backup it reports the disk is full. You can either erase the backup drive and start your backups anew or replace the drive with a larger drive.

MBP 15" video card problems while on battery power

I have a MBP 15" that I got about 3 weeks ago. I noticed that when I put it on battery power the video display becomes broken up laterally. I can drag the window or app window out of view then back into view and its ok. But if I start scrolling again, the text, image, video or whatever is on screen becomes distorted.
could this be a bad video card? should I try to get it replaced?
Any insights?
thanks!

I'm having the same issue--it looks like a tearing or smearing of lines of text, mainly in Safari, though I have seen it in Mail. I haven't noticed it related to running on AC or battery, but it may be...I had an older MacBook Pro (core duo) running 10.5.2 that was fine and recently upgraded to a 2.4 Core 2 Duo and this problem has popped up.
This issue looks suspiciously like a problem I was having on a Mac Pro with the ATI1900 card--it was brushed off for ages as a "heat problem" or the like with the card, and then miraculously after months of waiting a firmware update came out that completely cleared up the problem...

Stop the sleep blinking light in lenovo g-470, whining sound from the power adapter , HEEEEEELP !!!

Hi, hope anyone can help me.
I own a lenovo b560 and a g470, the sleep light will blink when I go to sleeping mode, anyway the problem is not the light, the problem is the whining sound it produces the power adapter when the light start blinking, in both machines I hear that whining noise, but in the g470 is much louder, I don´t know if this is because I have a faulty adapter or something, the strange thing is that both adapters make the noise when I sleep the laptop, when I turn off or hibernate the whining sound disappear.
Also, I notice that the whining sound alternate in 2 types of sounds, one is high in pitch and the other lower, the high pitch is when the blinking light turn on when go to sleep and the lower pitch of the sound is when the light go off, and that is repeating until I resume the laptop, it´s very annoying, especially when I´m in a quiet room.
So my theory is that maybe somehow I can turn off the blinking light when the laptop goes to sleep and then maybe the whining sound will go away, but I don´t know, it´s only an a idea.
Any help will be appreciated.
Thanks !
Solved!
Go to Solution.

I can really understand your pain with this issue.
Kindly update the BIOS and display driver from the lenovo website then check if the issue persist.
The issue should be resolved after this.

Using iBook G3 without battery - power adapter only

I would like to use my iBook G3 without the battery - just with the power adapter plugged in. I've tried starting up with the power plugged in and the battery removed, and no luck. Removing the battery with the power plugged in shuts down the computer.
I have an old battery that doesn't hold charge anymore and needs replacing. I use this computer from home 99.9% of the time and I'd rather not have a hot battery on my lap. Any thoughts or suggestions? I KNOW it's possible to do this as I've always seen demo models in stores set up this way. I have a relatively new adapter - the one that looks like an airport, not like a flying saucer.

Theoretically, it should work, yes. Have you tried resetting the PMU?
However, I strongly recommend against running with no battery for a couple of reasons.
First of all, even a mostly dead battery usually will hold enough of a charge to save your projects you're working on if the iBook is accidentally unplugged.
Next, if Apple had really intended using the iBook this way, they would have provided a battery hatch cover. As it is, using the iBook with no battery in place would subject the terminals to dust, lint, and debris. Needless to say, this is not good.
Apple has never really called its portables "laptops." They are not designed to run on your lap, but on a hard surface. I know most of us use them on our laps, but these days, I use one of these, which my son bought me for Mother's Day. I use it folded in half, and use the foot to prop up the back so that my iBook is kept cooler than it would be otherwise. It works great.
If the heat bothers you, it probably bothers your iBook, too. You may want to look into a similar solution. One long-time Apple user has suggested an inexpensive acrylic cutting board as a lap desk, and that would work fine, too. I don't recommend running without the battery, though, even if you could manage to do it.

Setup deskjet 3050A having trouble with the cord coming from the power adapter.

My deskjet 3050A power adapter has a black and white cord coming from it and ends with a a small black rubber and metal end. I can't figure out where this goes. My printer will not turn on anymore. It was working before I went in the hospital at the beginning of the month and I can't remember where this cord went to.

Hi,
Looks like your printer has broken during your absence, should be nothing hanging out with that description. I can't physically see it therefore I can't say anything because this can be live and death. You need an electrical or throw the printer away and get a new one.
Regards.
