G5 starting instantly after plugging the power cord - why?

Hi,
I have a problem with my old dual 2.0 G5 powermac.
From time to time I'm disconnecting all the cables and the power cord to open up the enclosure to do some house cleaning. I remove dust from the inside, because the g5 works also as a pretty good vacuum cleaner...
When I'm done, I reconnect everything, and start up again just by pressing the power button in front of the machine. But now the G5 starts instantly when I'm plugging the cord into my power strip. Why is something happening?
Thanks for help,
Michal

Glad it helped! often good step when there are hardware and power issues. Also, if your power current is "iffy" or anything, outages, brown-outs, overage, always good to add UPS and/or line conditioner (or both) which can also protect your equipment and investment.

Black screen when plug the power cord

Hi..
yesterday I bought a new laptop : hp 15-r138
When I plug the power cord - or unplug it .. the screen turn black for a second and then goes back to normal ..
Is this OK ?
Thanks

I've heard of this. Where when you do the update, if you let the screen go dim, or something you can't get it back because you can't see anything due to those controls running in the background at this stage of installation. I'm pretty sure you need to plug it into an external monitor to get it back maybe?

Turn off after unplug the power cord

Hi,
I have a MacBook Pro form 6-8 months and everything works great but from 2-3 days ago now everytime when i disconnect the power cord from the computer the system turn off.
I think the battery is good because i can use the computer only with battery (like im doing right now) and if i press the battery indicator button all green lights turn on and i can use the computer for 1-2 hours using battery only but for some reason if i connect the power cable again and disconnect later the computer is turned off.
I install all updates by apple.
not exist any kind of clear cmos, master reset or something like this

Computer shuts down after unplugging the power cord

My computer is showing a Plugged in, not charging message, but it is at 88%. When I unplug the charger from the computer to work somewhere else, the computer totally shuts down and will not power up unless the power charger is plugged in. I tried taking the battery out and leaving the cord connected and the computer started fine. How do I get the computer to stop shutting down after unplugging? Any help is greatly appreciated.

Sounds like battery #2 has a short. When the system detects a critically low battery, it is likely to devote all power to battery charge until the batery reaches 5% or so. Try each battery seperately. If no power at any time, remove the battery, disconnect the AC adapter. Press the power switch for about ten seconds. Then connect the AC adapter, let it boot, then install the battery and check the charging status. This resets the power manager. I think one battery id bad, but you will need to test them one at a time. Good luck.

HP ProBook 4530s orange blinking led, won't recognise the power cord

Hello!
yestarday I tried to open my laptop but it didn't start. i thought that maybe the battery was empty so i plugged the power cord, but nothing happened.
then I noticed the led near the power cord blinking orange. After a fast googling i came to this thread ( http://h30434.www3.hp.com/t5/Notebook-Hardware/charging-light-blinking-problem-with-hp-probook-4530s... )
using the 8-step guide I managed to boot the laptop just to realise that it won't detect the power cord!
It was really strange, because when I noticed this, my battery was already at 2%!
I shut down the laptop, and tried to open it without the battery, it booted normally, but it still can't detect that the power cord is plugged in!!!!!
On the other thread some mentioned to update the bios, but in my case where it can't detect the power cord, that's impossible, because the procedure requires the laptop to be plugged in.
Now the laptop won't start normally, I have to keep the power button pressed for 40 secs and then plug the power cord. In addition it won't work only with battery, and that is my biggest problem!!
What should I do now?

Macbook shuts off instantly when I unplug power cord.

Hello everybody.
This afternoon while I was watching a movie on my macbook, (it was on battery power, about 3/4 full) it just shut off. I could not turn it back on, so i plugged the power cord back in, it turned on fine, but whenever I unplug it it shuts down, even though it recognises the battery and charge level and all.
The thing is, when it shuts down it's not like if there was no battery, the screen dims, the battery icon changes to the one it has when its on battery power, and about 1-2 seconds later everything just shuts down. I'm just out of warranty (about 2 weeks ago). Do you guys think this is a hardware issue? I've gone through all the updates i have found on batteries and even reset the power management thing (where you turn the computer off with no battery and hold the power button).
Thanks for any help
-Cedric

HT4061 I updated my phone this morning and now it is stuck with an iTunes logo and arrow pointing to it and a pic of the power cord - the phone was plugged in when I started the update...now I can't access my phone at all

My phone is plugged in and the screen shows the power cord connector and arrow and the iTunes logo. I have made sure the plug is in and power on. Touching the screen does nothing. I have turned it off and back on I get an apple pic then back to the iTunes logo pic, arrow and plug....

I installed new update and have had the connect to iTunes all day. I got home connected to iTunes and it said my phone couldn't be updated it needed restored to factory settings. I was reluctant to lose everything so I ignored this and clicked update. After it installed it said to restore again. Again I ignored it and this time it updated my phone and my phone turned back on with everything there.
So glad I ignored the previous messages asking me to restore! You could try this if you have iTunes and don't want it restored to factory settings.

Have a G3 pismo, works great, but when I plug in the power cord, the light won't come on to indicate its charging. It is charging, and the battery is good, its just that the light won't come on. Could it be something with the backup battery?

I have a G3 bronze keyboard that works, with a good battery, but when the power supply is plugged in, the charging light on the back of the laptop
will not come on. It is charging however, and have two different apple power adapters and both will charge the main battery, it's just that the light won't come on.
Did a reset of the pmu, but no changes. The date stays current, but wondering if the backup battery could be getting weak and affecting it , or is something else going on?

The power connector in the G3 PowerBook is a weak link. Removed, it looks like this:
[image from http://microdocusa.com/specials.html ]
The connector probably hasn't failed, but the solder joints where "legs" on the connector attached to the logic/power board are under a lot of stress after 10 years of use. Little bumps and tugs on the power cord eventually degrade the connection. You can check for looseness easily---see if the connector feels loose when you GENTLY wiggle it with a fingertip. It should have zero play if it's still firmly attached. You can also plug in the power adaptor and see if slight movements if the plug make the light turn on. Pretty diagnostic of a loose connector.
The date stays current,
Make sure you are doing this check correctly. If you have an always-on internet connection, the date/time are fed froma network time server and will always read properly unless you test with the internet connect turned off or disconnected.

Satellite Pro U400 sometimes freezes when the power cord is plugged in

Hello! I know this problem has been discussed here and there but I would like to open a new thread on that. Here is the scenario.
I have recently bought a new Toshiba Satellite Pro U400-247 (PSU45E) with two batteries: (a) the original one, (b) additionally purchased Toshiba genuine PA3636U-1BRL, 7200 mAh. The notebook has the latest BIOS (4.80) and the latest drivers downloaded from Toshiba and installed (ConfigFree is not installed). I am using XP Pro SP3 (clean install done by myself). Everything is working very well, except for one thing:
Sometimes (but not always), when the notebook is working on battery and I plug in the power cord, everything freezes and I have to restart. Some observations:
(a) it tends to happen more frequently when the low battery alarm has already sounded;
(b) it seems to happen more frequently with the 7200 mAh battery and less frequently with the original battery;
(c) it seems to happen more often when a USB device (e.g. mouse) has been connected with the notebook, but that is not a rule;
(d) it seems to happen less frequently when I move the USB mouse at the time I am plugging in the power cord;
(e) I have experimented a lot with Toshiba PowerSaver's settings (e.g. changed the CPU levels for my profiles) but nothing I have modified seems to change the situation;
(f) I have tried various suggestions I found on different forums, but no avail (e.g. BIOS settings);
(g) otherwise, I can say that I really have not seen a smoother computer, everything else is really working just fine, no other problems whatsoever :)
All this makes me think that this must be some kind of bug in the motherboard drivers, the PowerSaver driver or other drivers interacting with the battery, the CPU or possibly USB. Is there an explanation for this problem and can it be rectified somehow (e.g. by providing a driver update)?

Hello, thanks for the reply!
My bad, of course I meant the chipset driver. That, however, does not change the essence of the question. Also, I know that a notebook should function properly even the AC adaptor is connected or not connected. That is why I posted my question.
As for the OS reinstall, sorry, I would not do that just on some wild guess from somebody. I recently finished the clean OS install. I have installed XP on dozens of notebooks in my life and I know what I am doing. I have been into computers and networking for 15 years and I know when I see a problem not related to how I install my OSes.
My personal opinion: this problem has not to do with the OS install since the same problem also existed when I test-installed the XP OS image from Toshiba's own downgrade CD (that was before I did a clean install from my own slipstreamed CD). And, if you really use a properly and carefully configured OS with all the necessary software, an OS reinstall is not something you just do every day.
As for the rest (testing the memory / adapter / motherboard etc.): as I have mentioned, similar (although not identical) topics have been raised in various other instances (e.g. at http://laptopforums.toshiba.com/t5/B...EABCA64EE6C5D9) . That means that this problem is most probably not specific to my computer or even to U400 but it may happen with other Toshiba notebooks too. Therefore a (rather standard) suggestion to spend days on reinstalling (and in my case, carefully reconfiguring) the OS, checking the memory, adapter, mobo etc. does not sound as the most plausible one in this case. FYI, I always do full tests on hardware right after I have installed an OS. In this computer, all tests (Toshiba's own; 3rd party memory diagnostics, HDD diagnostics) were passed OK. Indeed, I did not have the AC adapter tested but as it otherwise works fine, the possible problem (if there is one) would be a minor one to notice, and would require testing at a Toshiba service centre (there is no direct Toshiba agency in my country). I think testing the AC adapter is the last resort as much more probably, the problem lies somewhere else.
Even if this problem is hardware-related, I do not expect Toshiba to replace all such hardware out there. However, on many occasions, hardware-related problems can be cured or alleviated on the software side (e.g. by a driver or BIOS update). Since it seems that other people are having similar problems with Toshiba hardware/software, I thought that maybe someone has found an actual solution or maybe there are Toshiba employees reading these forums who could look into it.

My Macbook pro keeps shutting down right after I log in. The power cord seems to be fine, so I think the computer has enough power. Right after logging in, it shows a grey background with a loading bar that loads only 1/4. Then it shuts down.

I have had my Macbook Pro since 2011 and it has been great until now. Suddenly, I can no longer get past the grey screen just after I log in. The grey screen appears with a loading bar, and the bar get 1/4 of the way complete, then the computer shuts off. My power cord seems to be working fine because this problem still occurred after using another power cord (from another Macbook). Keyboard does not light up, and the small green lights on the left side of the computer do not light up (this is an older version and these light indicate how charged the computer is). It is using the OS X Yosemite and recently had total clearing of the hard drive as it was transferring from one owner to another, so the hard drive isn't nearly full enough to be causing this problem. I've never run into this problem before with other Macbooks.
Help!

Hi. When you were in the recovery drive doing permissions, did you try and run a repair of the boot drive? Did you try single user mode? Try these first and then go back and try to reinstall the operating system.When I say repair boot drive I don't mean permissions. There are both options in disk utilities.When you open disk utilities ,you will see in the left column two drives plus possibly a boot partition that look like an external driv. click on the second drive and in first aid use repair disk. If you still can't boot and it will not let you restore, you may have to do a clean install. http://support.apple.com/kb/PH18869?viewlocale=en_US

I have a Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power off button. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Any ideas?

I have a Power Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power on/off button again. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Sometimes my Mac goes on just by pressing the power on button but most times I have to pull the power cord and put it back in. Any ideas or help out there for this? Could it be a failing power supply? Apple Care says that this model is obsolete so there is no help from there. John

Hi John,
That's often a sign of a bsad Capacitor in the Power Supply, but...
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Running an old MacBook Pro 2.5ghz core 2 Duo. Battery went chemical meltdown and expanded out of its housing. Removed it and was running off the power cord. This worked for a while. Now it won't start up. Have a Replacement on order. Is there a bigge

Running an old MacBook Pro 2.5ghz core 2 Duo. Battery went chemical meltdown and expanded out of its housing. Removed it and was running off the power cord. This worked for a while. Now it won't start up. Have a Replacement on order. Is there a bigger issue or does a battery need to be in the compartment to boot up? Appreciate any help. Thanks.

Working battery needs to be in for the computer to function.

My MacBook Pro just shut down without notice. It had about 40% of the battery life. It will not turn back on and I noticed when plugged in the little light on the power cord is blinking orange, not a solid green like normal. Anyone have this issue before

MacBook Pro just shut down without notice. It had about 40% of the battery life. It will not turn back on and I noticed when plugged in the little light on the power cord is blinking orange, not a solid green like normal. Anyone have this issue before? I've only had this for about 3mos. I called apple support. They tried one thing then said I have to take to the apple store. Unfortunately I don't have one nearby. So before I travel an hour+ away I thought is give it a shot on here. Thank.

Hi S,
Did they have you try an SMC Reset: http://support.apple.com/kb/HT3964?

HT4060 Where on the iPad mini do I plug in the power cord?

I just bought a new iPad mini and need to recharge the battery. But I don't see where on the iPad to plug in the power cord. The power cord has the same male connector as my iPhone 4. Help!

Use the cable that came with the iPad mini, not with your iPhone. Different connectors.

Why can I not play music through my headphones while the power cord is plugged in?

When my headphones and power cord are plugged in at the same time, audio will not play through the headphones, and the volume bar goes away. Why?

What is the other end of the power cord plugged in to? If it isn't an Apple wall adapter the phone probably sees it as an audio device.

G5 starting instantly after plugging the power cord - why?
