Satellite M55 turns off when disconnecting power cable

Hi,
when disconnecting my laptop from the outlet rather than switching to the battery, my laptop will often simply turn off even though the battery is completely charged. Other times things work as they should.
I did some searching and my problem appears similar to the one detailed here in this post.
Might anyone know the solution for this problem?
thanks.

Hello Luc
Like in other topic described, you should contact service and explain them what happen exactly. I am afraid there can be something wrong with power supply electronic. We can here just speculate about it.
Unfortunately I am afraid there is nothing you can do alone.

Satellite M60/M55: Turns off after disconnecting power

My M60 sometimes turns off immediately after unplugging mains power (either the AC mains or DC plug from the laptop), instead of resuming on battery power, although the battery is full.
The battery is OK & the laptop starts up regularly on battery power after pushing the on switch.
The Toshiba Power Saver seems to work OK & I have the latest BIOS.
I always save my work before disconnecting, but I still don't like this behavior & would appreciate some good advice.

I had the motherboard replaced for another reason and was fairly surprised to notice the problem after replacement (but without OS reinstall).
The main suspect is the TPS and its driver; some months ago a new version was released on Toshiba support site for M60 (though the file dates are not fresh, and I believe I have installed this version earlier).
So, I removed both TPS and TPS driver. I tested many times and it did not happen again. Not even when I reinstalled them.
While testing I turned off HD write caching to avoid file corruption problems (but this slows down HD operation, most notably hibernation).
I'm not sure if this actually works because also earlier the computer would shut down just occasionally, not every time. But this may be a clue in case you have this problem. If you do, please test and report the result, no matter what the outcome is.

What to say dude. The problem is that this issue happens ONLY sometimes and therefore its not easy to locate the real reason for such shutdowns.
However, I would try to provide some useful hints but first of all it would be useful to know how old your battery is.
Fact is that old and stressed batteries lose the own performance very quickly.
My battery is about 3 years old and my notebook would run on the battery for about 10-20 seconds even though its fully charged. The performance is simple very weak!
At the other hand the issue could be related to the faulty power supply electronic on the board
As you see its not easy to say whats exactly wrong and as already suggested in the other threads (locked) you should ask a technician for a notebook check.
The guys could run some diagnostic tests and could locate fault.

Is there away of having the iPad NOT turn off when on power?

i am trying to show a clock and countdown timers for exams but after 10 mins the screen turns off, i have found a setting for auto lock and change it to " never but it keeps happening. Running ios 7
Didnt have this issue before the update

Go into the iPad's settings.
Choose General settings from the list on the left side of the screen.
You will find the Auto-Lock setting midway down the list. This setting allows you to choose how long the iPad waits before going to sleep.
Choosing the Auto-Lock feature will bring you to a new screen with the option to auto sleep after 2, 5, 10 or 15 minutes. You can also turn the feature off completely by choosing Never.

Laptop freezes when the power cable is plugged in.

I have a satellite A205-S4777. When the power cable is plugged in the machine freezes. The machine works fine when working on battery power alone. Any suggestions?

I'm assuming this is out of warranty. If you're comfortable doing so, you could use a digital multimeter to check the output of the AC adaptor and ensure it matches what's on its label. If it's incorrect, you would need to purchase a replacement AC adaptor. If it is correct, the laptop might need servicing. If you're not comfortable using a digital multimeter or don't want to purchase one, you still might want to take a guess and try replacing the AC adaptor, but you can't be positive that it's the cause.

I hope you are able to solve your problem. The iPhone is definitely designed to be able to run the power all the way down. In fact, the instructions to maintain your battery suggest doing that once a month. I do it now and then, not usually once a month and I am always able to get my phone back to where it would be usable in about 10 minutes of charge. I always keep it in the charger until it is fully charged, however.
I just didn't want you to think you made some big mistake to let it run out of charge. There must be something going on with your phone or the battery.

I have lost my iphone and the power was turned off when i lost it and i dont have find my iphone installed what can i do?

I have lost my iPhone 4s and i had it turned off when I laid it down somewhere and I have not installed the find my iPhone app. Is ther anyway possible to locate it.

Nope. If you didn't have find my iphone turned on, you will not be able to locate it. File a police report, and contact your carrier.

Pavilion dv6- turns off when power cord removed

There's a certain way I can unplug it where it doesn't shut off- but 99% of the time when the adapter is pulled out it shuts off. Has a new battery that shows 100% charged, and lasts a good hour if I can get it to stay on when unplugged. ONce it shuts off, it only comes back when the adapter is plugged in. Do I replace the adapter, battery (again), or something else?

Hi @SavannahsDad
Welcome to the HP Support Forums!
I understand that your notebook turns off when the cord is unplugged. I am happy to assist. If the battery is showing as fully charged whenever you do this it almost sounds as if there is a bad connection between the battery and the notebook.
Here are some things you can look at for now.Computer Does not Start (Windows 7, Vista, XP)
AC Adapter Battery Charging Indicator LED Does Not Display Immediately When Plugged In
Battery Charging Is Not Indicated in Vista or Charging LED Does Not Turn On
Improving Battery Performance (Windows 8, 7, Vista)
Let me know if any of that is useful to you, or if you see any other symptoms.

Wifi turns off when screen turns off

Hi all. I noticed that my wifi turns off when my screen turns off (to save energy) on my brand new rMBP. The mac isn't asleep, just the screen as I have specified in the settings to turn off but the actual laptop is still on. Well when I move the mouse or press a key, the screen naturally comes on right away but I noticed that wifi turns on and reconnected. So if I was streaming music or something, it would stop and disconnect when the screen goes off. Does this make sense?
How do I disable this? I don't want my wifi to turn off at all when my screen turns off. If I'm downloading/streaming or whatever, I want my connection to remain on. Thoughts?

edit:
i know there's the option "prevent computer sleeping when screen is off" under power adpter, but i would like it done while running battery.
thank you.

I own an iphone 3gs and it just turns off when it wants, like when its loading something? does anyone know whats the problem?

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Ipod nano 4g works good as locked. turns off when unlocked

works good as locked. turns off when unlocked

If you have the Hold switch ON and it's connected to power, the iPod is ON... What happens when you disconnect it like that? Does it stay on for any length of time? Does it immediately turn OFF?
If it immediately (or within a few seconds) turns OFF, I'm not sure what's going on with the Hold switch, but your battery is probably worn out and not holding a charge.
If it stays ON, you are saying it will turn OFF if you move the Hold switch to the OFF position?

Macbook works fine when plugged in, turns off when unplugged.

Hello all,
As stated my 2008 Unibody 13 inch, serial number W8******1AX turns on and works fine when it is connected to power.
When it is unplugged it instantly turns off and turns its fans on full until it depletes the battery (so it is obviously getting power.. just not where I want it)
Since the problem began I have tried two new batteries, neither of which had any different symptoms.
Before this, the computer had an intermittent life, it would turn off when it saw fit, which got progressively worse.
I have followed the guides to resetting the SMC but have had no luck
I have been running it without the battery (to save it charging and discharging for no reason) and sometimes when plugged in without a battery
the magsafe green indicator light goes from dim to bright.
With the battery installed it stays bright orange until it is charged and then switches to bright green.
(I have tried it with another charger, same symptoms)

There may be a hardware cause behind the symptoms you cite, so a diagnostic
is recommended to see which parts are weak or failed in the computer. A visit to
an Apple Store with Genius bar may be helpful, as they can perform testing there.
A call ahead or use their web page, to schedule an appointment, is advised.
In the US and Canada, the Genius bar at a retail Apple Store can perform
a diagnostic service, for no fee, even on Apple products without AppleCare.
See links:

Genius Bar - Apple Retail Store:

List of Apple Stores, cities, countries:
http://www.apple.com/retail/storelist/
Also authorized Apple service providers who can test, repair and guarantee their
work should be able to handle an out-of-warranty older Mac, within age limits...
Ones too old for the Apple Store could be serviced at a Specialist, instead.

•Calibrating is part of maintenance, esp with older portables:
Apple Portables: Calibrating your computer's battery for best performance
•The power adapter can be problematic and cause issues, so there's this:

Also another item, other than keeping the magnetic connections clean of
debris, grime, and corrosion, is to check the MagSafe Board or have it
checked as part of a greater diagnostic. This board is behind the port
that supplies the computer and the battery with power from the adapter.
When it partially fails or if/when one of the connecting wires or plug fails
you can find odd issues or partial use. The battery may charge but it
may not be able to power the computer, and other odd effects.
https://www.ifixit.com/Device/MacBook
In older portable Macs, this was generally called a 'DC-in board' and as
such, you could read about it in an iFixit repair guide for the MacBook
model you have. These vary so the matching article is recommended to
see if that is something you may want to try. But I would have diagnostic
testing done and avoid additional damages from attempted DIY efforts.
There have been a few reports of other failure on the logic board that
contributes to a partial failure of the charging system, so about all this
may do is troubleshoot around the failure without finding an exact cause.
However it goes...
Good luck & happy computing!

I'm sure your'e going to tell me I just need a new phone but maybe there is hope for my iphone 4. It will not charge past 66% (it's not the charger), it turns off when unplugged, and it will not even let me turn my wi fi to the on possition. Help!

Hi there 8472kck!
I have some information for you that can help you troubleshoot this issue a little further. That information can be found right here:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
