PowerBook crashes with power cord connected

I have just upgraded my memory. I added another 512MB to the existing 512MB. Everything runs fine until I connect the power cord. The system crashes/ freezes as aoon as the power cord is connected, and the system will not start with the power cord connected. I have tried taking out the battery and starting with just the power cord witht the same results.
This would not be such a big deal if my battery had some life left in it, at the most I can get 45 minutes before I have to recharge.

Try setting your energy saver processor speed settings to "highest" for both battery and power adapter operation. If this fixes the problem, your second ram chip is not "bus slewing" compatible. See http://discussions.apple.com/thread.jspa?threadID=227369&tstart=0

Crashing mac. power cord?

I've heard of laptops and macs etc. battery dying and will not power without power cord in, however my mac seems to keep crashing if power cord is in and gets knocked or taken out, however left for about 30seconds off will power up again without power cord in... but power cord will then not work until i've unplugged from the wall, fiddled around with it for a bit... after about 5 mins the power cord will work again.
This happens every time the cord is knocked or taken out. Also, after crashing the macbook will then ask me to confirm "incoming connections" .. after googling what ones they were they were things from my microsoft office package and mail and nothing suspicious. Clock will also go to 00:00 1/1/ etc, but if i click on the date& time preferenes it sorts itself out and goes back to normal date and time.
Itunes also restarts and needs me to confirm... not sure about other programmes yet.. but no files or data has been lost.
Just everything resets?
Wondering if anyone else has heard of this? If anyone might know if it's the power cord tripping out and somehow glitching the macbook?
I don't have any issues with my battery draining abnormally, and once the power cord is up and running and plugged in, it's charging fine. Just a bit confused. I've never heard or experienced anything like this before!
I live with my laptop for my uni stuff so any info would be great!
Thanks, Georgie
Ps. I have a express lane phone appointment booked for friday, but just wondered if anyone had any information in the mean time.

Hi...it sounds like I've been having similar problems as well. This has happened when I tried resetting the SMC twice and the PRAM.. it has done it twice since then after fiddling around with the adapter. It's like it goes to sleep by itself right and then you awake it and then it shuts down? When I restart it I'm having to press the power button lots of times to get it to start and then it tells me to accept stuff and reset the clock. Same symptoms you are having? If you find out what the problem is, and if I'm able to fix this too myself...I'd like it if you post back here! I'm also having problems with the battery showing "Not Charging" on the indicator and having the adapter light a steady green, which I am going to have to get it looked into as well. Thanks!!!

Powerbook crashes with DSL modem voyager 105

Hi,
I use a Voyager 105 USB modem for broadband access. About every second or third time I use this, my Powerbook crashes with kernel panic and requires a reboot. Any ideas how to solve that?
Thanks.

Powerbook 12 Mac OS X (10.4.5)

As suggested by Daniel and Gareth, USB modems like the Voyager can be prone to driver issues. Problems can sometimes be resolved through updated drivers from the manufacturer.
However the best way to resolve the problem is to invest in an ethernet modem/router instead as these do not require any drivers. Most of them also allow you to share the internet connection with other computers on the network.
Assuming you are UK-based, there are many vendors who can supply perfectly capable ethernet-based products for comparatively low cost. Amongst them are ADSL Nation and DSL Source (I have no affiliation to either of them except being a customer).
You can also get further information on ADSL products and services from ADSLguide, which also has a dedicated Apple section (with some very helpful and knowledgeable people) on their discussions forum.

I book doesnt work with power cord only

Hello. I was just using my ibook g4 and shut it down. When i tried to turn it back on it worked for about 5 minutes then it shut off. I tried taking out the battery and holding down the power button for 5 seconds among other things. I gave up and borrowed a friends battery, he has the same model as me and that battery doesnt work either. I tried just using the power cord only and that doesnt work either. Do i need to take it in to a professional? I've tried just about everything.

Hey Caesar and Welcome to Apple Discussions,
So your header reads:
"i book doesnt work with power cord only "
Is that right? Will it run only on the battery?
If so this is from the manual:
"The computer runs with battery, but not with the power adapter plugged into
wall outlet
1. Try known-good power outlet.
2. Try known-good power adapter and power cord.
Note:
Verify that power adapter connector glows amber or green. If the power
adapter light is green, turn over the computer and press the battery button. The
battery lights should glow green and stay on if the power adapter is operating
correctly.
3. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager means you will also need to reset the
date and time (using the Date & Time control panel).
4. Replace DC board.
5. Replace logic board."
and it would help to know exactly which iBook you have but this is pretty generic.

Macbook will not start up with power cord plugged in

hi,
my macbook core duo, wont startup anymore with the power cord.
It does work with a battery though. But the problem is that the cord is not charging the battery anymore and not even giving power to the machine.
the light on the cord is green. I tried with another power cord, it does the same.
i even changed the dc-in board, with no luck.
any ideas ?

I have the exact same problem. There is a buzz from the region where the power connection is, and I'm afraid it is a power hardware issue. Since the optical drive already quit on this first gen MacBook, I think it's time to chuck this lemon.

MBP random shutdown even with power cord plugged in

My MacBook Pro (original) has now randomly shut down 5 times since I installed 10.5.6 the week before Christmas. 4 of those 5 times happened with the power cord plugged in, the green indicator light on and the installed battery fully charged. I have two batteries and it has happened with each of them at least twice. Yesterday I got my first shutdown while on battery only. After each shutdown I was able to restart the computer and it operated normally, even the one on battery only.
These shutdowns are fast and complete. There is no warning of any kind. The screen just goes blank. It is not sleeping, there is no pulsing light on the front. Using the start key begins the process from scratch with the Apple "startup chime."
The occurrences have gotten more frequent. The first two were within 24 hours of when I installed 10.5.6 and they happened within several hours of each other. Both of these were with the power cord attached and fully charged batteries. I swapped the battery after the first one. When it happened again, I swapped them again.
The next time I had the problem was 1/30 (last Friday). The only significant software installation I had done between installing 10.5.6 and then was to install iLife '09 on 1/28. All software updates had been installed in a timely manner. Friday the laptop was plugged into external power and the battery was fully charged, but I don't know which battery was installed.
2/1 I had an issue where my computer couldn't locate the OS file on startup so I did a archive and install. It operated normally since then until yesterday, 2/4 when I had two shutdowns. The first I had the computer on external power and a fully charged battery. The second was the ONLY time I have had the shutdown occur while on battery power only. I was on a flight when the second shutdown occurred. I had used all the power in the battery that was installed when the first shutdown happened (down to about 11 minutes remaining). I then swapped batteries without shutting the computer down. The system rebuilt itself normally and I began working on iPhoto. About an hour later it just shutdown. I was able to restart the computer normally and used it for another 45 minutes or so before I shut it down for landing.
I called Apple Care this morning and they advised me to get an appointment with a Genius. I resist being without my laptop but will try this and let them look over the console log to see if they can find anything.
I have done all the basics, reset the PMU, zapped the PRAM and repaired disk permissions. The next thing I am going to do is to calibrate both batteries. I doubt this will have any impact on the issue because most of the shutdowns have occurred with external power connected. I just haven't done this in a while.
Any ideas out there? Anyone have a similar problem?
I have another issue on my Mac Pro since installing 10.5.6 and my wife's iMac G5 has a completely different issue since installing 10.5 (I didn't install this OS until last week so I could get the new iLife on it). Seems like this latest OS version is a bit buggy or at least incompatible with a lot of Apple's products in different ways.
Fight On!

UPDATE:
Service was due and now that I saw the machine fail 4 times in a day doing the same process I knew I could duplicate the issue on demand. That's a big bonus.
Called Apple Care yesterday morning and the guy I spoke with read over the notes on my case after I told him what happened the day before (black friday, 4 shutdowns). While he didn't transfer me to a Product Specialist, he did talk to one for quite a while (I was on hold for about 20 minutes while he did this). He said I could ship it to Apple and they would look at it or I could take it to an Apple Store or Authorized Service Center. Thinking this was the next step I had secured a time at the Carlsbad Apple Store for late that afternoon (my usual & closest store, Escondido, was booked all weekend). They told me to take it in and reference the case number. The Product Specialist thought it sounded like a logic board and would duly note that diagnosis in the case history.
After the conversation ended I decided to make sure I could cause the failure. So I started the process (threw out the face.db from the iPhoto Library package and opened iPhoto whereupon iPhoto begins a scan of the images for faces. Having over 12,000 images gives it a lot of work). This time I decided to monitor the workings of the laptop using iStat Pro (freeware widget download & I recommend making a small donation it's so good). I kept track of the processes at 5 minute intervals, the CPU usage, numerous temps AND the fan speed. The latter seemed to be the critical. Shortly after the fan speed got to 4700 the shutdown occurred. It took 36 minutes from the time I started. The fans kind of confirm to me that it could be the logic board.
I took the laptop to the Apple Store and started the process in front of the "Genius." He read through the case as well as the printed copy of this thread and other notes I brought from previous shutdowns including the data I mined from iStat Pro. He was unimpressed and thought it was a non-issue. I guess that's only fair because I was unimpressed with him. He figures it's my system because of a software conflict somewhere. His answer was to do a clean install and reinstall all the software from the original disks. I told him I have spent over 50 hours on this issue to date and that what he was suggesting would take at least that much and guarantee nothing if it's a database issue...duh! Disagreement. Oh, and he also doubted it would fail just from making it work.
43 minutes after starting the process, well after my "Genius" went home for the day (I was his last appointment), the failure occurred. The "Genius" he handed me off to was working with someone else next to where I was sitting. When the fans hit 4700 rpm I told her it was going to happen soon and as I finished my sentence the failure occurred! Cool.
They have the machine and I'll let you know what they do.
Fight On!

Power cord connections

I have a Pavilion ze4300 which the power cord was ripped off the mother board. There is a 1 conductor shield from the ac/dc converter to the mother board and a small metal jumper. There are 3 solder holes in the board. Can anyone tell me where they get connected ?
Thank you

The power outage may have created a power spike and unless your computer is connected to a UPS or very high quality surge protector there is a chance the power supply is dead. If you don't hear any sounds and do not see any video when you turn it on there is a good chance the power supply is gone. You can try doing a SMC reset (iMac SMC and PRAM reset) and if that does not work make an appointment with an Apple Store Genius or take the machine to your local AASP for repair. If you don't know of any AASP's in your area please use Contact Apple for support and service to help locate one.

HP G62 Will Not Boot With Power Cord Plugged In

I have an HP G62 laptop that is about four years old. I've had a couple of problems with it before that were resolved relatively satisfactorily, however five or six months ago I started having a new issue. The laptop will not boot with the charging cord plugged in, whether there is a battery in it or not. Nor will it return from sleep mode (screen black, status light on the power button flashing) with the charging cord plugged in, whether there is a battery in it or not. It simply shuts down and I end up with an error screen the next time I boot up. I have tried other charging cords and it has been the same, however the cord will still charge the battery. This means I have to charge the battery, unplug the cord, boot up the computer. This annoyance is worsened by the fact that the battery is old and unable to hold charge for very long at all and I fear one day even the battery won't be enough to boot the computer.Can I fix the power cord issue? Should I buy a new battery? Or let my computer give up the ghost and scrounge for a new one? Any help would be greatly appreciated.

the charger input could possibly need replaced and/or the charger

MacBook Pro crash when power cord is removed

When the power cord is disconnected the computer shuts off within about 0 to 15 minutes.
The log files do not show any fatal errors that have caused the crashes.
the only error that keeps repeating is: com.apple.launchd: (com.apple.launchd.peruser.32710[614]) getpwuid("32710") failed
However, i do not believe this would cause the crashes.
Any ideas?

No sleep function with power cord

My 2011 macbook pro does not go into sleep mode with the power cord on. The sleep light goes on, but does not go into "pulse" mode and the fans continue to run as well as the hard disk keeps running.
The issue started a few weeks back. I have tried switching off the internet sharing and other possible settings that might hinder the MBP going into sleep mode when the power cord is in. I have even down loaded PleaseSleep but that does not seem to function either.
Any ideas, anyone?
Anyone know if Apple is working on fixing this issue?
Seems like a minor issue, but if the MBP does not enter into sleep mode correctly I am afraid the built-up heat might damage disks, rams or screen.

OK, so it's not a hardware problem else it woudn't enter sleep under Guest login.
I'd first start looking at any programs you installed since it worked ok, maybe a utility or something?
Oherwise you can try to isolate the ones as I mentioned in Activity Monitor, by closing any programs that appear different from the ones when in Guest login. Not easy I know, but it might point to something stopping sleep working.
Also check in System preferences that all sharing is off, as this can keep the Mac from going into sleep. You can always turn these back on once you've established the cause.
Failing that, it looks like a trip to a local Apple dealer

Macbook Pro won't wake up even with power adapter connected

If I use my Macbook to the point where the battery completely die, it will not power up again even with the power adapter connected. It takes about 15-20 minutes of charging before it will wake up again. It seems as though it can't draw power directly from the adaptor, but must wait until the battery is sufficiently charged, and draw power from the battery. I can't imagine this is a design decision. Any help?

Part of this time may involve attempting to read a damaged sleep image file, bewlatbrutha.
You should note, too that the batteries in these computers have a built in microprocessor of their own to try to prevent them from being damaged by discharging too deeply. If you discharge to the point where even the battery's own processor has to shut down you may never be able to resurrect your battery without outside help (and sometimes not even then). Almost all Lithium Polymer and Lithium Ion batteries (regardless of what they are fitted to) have this sort of protection. The battery has to have a certain minimum charge at all time to keep its own processor running.
Even without reaching this point it is not good for Lithium batteries to be regularly discharged to the point where the computer has to sleep or shut down. You risk severely shortened battery life if you do this regularly.
Cheers

My MacBookPro 10.7.5 had been streaming tv thru the mini port/HDMI cable. Suddenly it stopped working. My tv screen is now black. I have tried restarting the computer with the cord connected. The computer is otherwise working.

I had been streaming tv with my MacBookPro 10.7.5 for several years using a cord from the mini port to the HDMI plug on the TV. Suddenly it stopped working. My computer otherwise works fine but there is my computer screen image is no longer being transmitted to the tv. The tv is black. I have it on the correct input.
I tried restarting the computer with the cord attached. Thanks in advance.

Test the cord on another external display or test with another cord.
Ciao.
