Lenovo G550 does not charge properly.

Well, hello everyone.
I have been experiencing a problem with my Lenovo G550 lately. It doesn't charge properly and at most cases, I have to charge it when it's turned off. When I start up my laptop and as soon as I get to the Windows login screen (or not even up to the loading screen), the power LED starts to blink. I log in to see the laptop not charging. I have tried everything you'd usually do such as, turning the laptop off and on after awhile, removing the battery and putting it in after a few minutes or maybe even an hour, check the charger, take the charger in and out of the laptop and even letting the laptop rest for awhile without the charger or battery in. Sometimes even after all that, it seems like it still doesn't charge. Sometimes it does charge when turned on, although, only charges for a few minutes and stops charging. Even when switched off, sometimes, it doesn't charge properly either.
If you know anything that would fix this, a suggestion or if you know why I'm having this problem, please reply to this.
Ah, silly little computer.

I have a friends laptop hoping to fix a common issue (or as I thought) of a broken power adapter socket. Without the battery in place when you plug the ac adapter in you get no lights and when you press the power button nothing happens.
Upon disassembly and also with the use of the internet I found that Lenovo actually has a nice setup where the yellow socket is removable retained by a single screw, with a pigtail and plug for the main board. So I pin tested the plug using an ohm meter and it tested good. Then I reattached the plug to the motherboard and tested it using the ac adapter and got 20V between both blue and black terminals. Then flipped the board over and I got the same results on the pins on the back of the board so power is getting to the solder points. But that is where the trail went cold.
Anyone have any ideas? I won't recommend her to buy a new motherboard at this point of even go to the expense of having it checked out which would exceed the value of this unit.
I am thinking there is a voltage regulator somewhere in between the battery and the mainboard power that might be the cause but that is above my electronic prowess.
One thing I can say is if this is not a simple fix I will guide her to look to another brand for a replacement. I have it stripped down to the mainboard and tempted to reassemble it to see if it really does charge the battery but just doesn't let you know via the charge lamp. I do know it won't run without the battery pack which has a little power left but saving it for now.
Can anyone help?
Thanks,
Steve

Lenovo G550 does not charge battery!!!! please help!!!!! :c

So i havent used my Lenovo for about a year and a half because i had lost the originial charger. ive recently bought a new cheap charger from amazon and thought it was the charger that was the problem when i looked it up online and found out it may be a bug from Windows 7. Now, this charger does turn on my laptop, but it does not charge it. It simply says "plugged in, not charging" and when i was reading an article on how to fix this , i was trying for hours to uninstall a program under device management called Microsoft ACPI- Compliant Conntrol Method Battery, because it was said that uninstalling this would help the system charge again. but after countless hours, i found that the program reinstalls itself and i am left with a laptop that just wont charge. my laptop says 0% (plugged in, not charging) and i really need this to work for the upcoming school year. i dont know what else to do! whenever i disconnect the wire the system completely shuts down and if i dont fix this problem ill just have to get rid of my Lenovo G550, which i absolutely LOVE! please, anyone help me! do i need to install a new version of windows? do i need to uninstall something? or is my laptop absolutely done for?
please, please, please help!!!!!!!!!!!!!!!!!!!!!!!

hi Chernandez51,
Welcome to the Lenovo Forums.
From your observation, it seems like the battery was fully discharged after not being for a long time (batteries degrade overtime due to age, heat, and usage).
What you can try is to charge the battery for an hour or two while the computer is off then observe the status light indicators.

If the battery still doesn't take a charge then the battery might have gone faulty and needs a replacement.
For best compatibility, I recommend you use a Lenovo approved AC adapter and charger. You can buy one from the lenovo spare parts website (www.lenovospareparts.com) or you can buy online (eg. Amazon, Ebay, etc.) but ensure that there's a Lenovo FRU part number on the item..

My iphone 4 switches off unexpectedly and does not charge properly every time

My iphone 4 turns off unexpectedly and does not charge properly every time. Can anyone help

Hey bigstu29,
Thanks for the question. To completely isolate the issue, you may want to follow these steps:
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 LCIs and 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.
For additional information, see this article:

Lenovo G500s does not charge!

Hey folks,
im sorry, im probably in the wrong theard!
I have a problem with my new! Lenovo G500s.
When i have my charger on my notebook it doesn't charge. There is standing:"Network operating will not be charge".
The realy bad thing is, that wehn i didn't have my cable on my Notebook it lives not longer than about 15 minutes. After these 15 minutes my screen is black and i can not start my Notebook. I have to charge again, and wait over hours to start my notebook again.
Can someone help me?
Thank you!
Felix
ps. Sorry for my bad englisch. I hope you understand what i mean.

hi Felix,
Welcome to the Lenovo Forums.
Just to verify, when you turn off the computer and plugin the charger, can you observe the battery light indicators and see if you're able to charge the battery.
G500s Battery Status Indicators
On the other hand, 15mins battery life is very low. If you have a 100% charged battery and it only last 15mins I would recommend calling Lenovo support as there's most likely a problem with the battery.

Lenovo A3000 does not charge

I let the tablet ran out of battery, then tried to charge but it didn't work. If y press de On button, it turns on, shows home screen, and then turns off.
What can I do?
I'm using Windows 8, i read sth about a brick, but the solution uses windows 7.
Thanks

Hi MikeTov,
are you sure you have Windows 8 running on an A3000 because it is essentially an Android device? Maybe you could check exactly which Lenovo system you have and re-post.

I'm not sure if there is BlackBerry 8250. Probably 8520? What OS are you running? Updating to the latest OS might solve the battery problem.

If after you charge it for about three hours and it only last about five minutes the battery is probably dead or there could be another hardware problem. I would go back to the Apple store and ask them specifically how can it be OK if the fully charged battery only lasts five minutes.

Hi, RomeroSalsa.
Thank you for visiting Apple Support Communities.
I understand that you are experiencing an issue with the responsiveness of your iPad mini while charging. I would need a little more information on how you are charging the device to provide a better answer. While the steps below are not exactly labeled for this issue, they may help resolve the issue.
If the battery doesn’t charge
If the battery doesn’t charge, unplug your device and try these steps:
Look at the connector at the bottom of your device and make sure it’s free of debris.
If you're using a USB power adapter, make sure it's plugged in all the way and the power outlet is working. If you're connecting to a computer, make sure it's on and can charge your device. To charge an iPad, you might need to use a USB power adapter and plug into a power outlet.
Try a different USB cable, USB power adapter, or USB port.
If everything seems to be working, reconnect your device and wait for 30 minutes.
If your device still doesn’t charge, try to restart it while it's connected to power. If you can't restart, reset your device.
If you can’t charge your iPhone, iPad, or iPod touch

Battery does not charge after rescue & recovery

Hi,
Yesterday I set up my computer fresh from the preload on the harddrive due to slowness, instabilities, inability to use VPN etc. After the reinstallation of OS and securiy updates, my battery does not charge anymore. The battery indicator on the front panel keeps blinking, and the Lenovo message center reports that irrepairable damage has been done to the battery and that it must be replaced.
My battery is not among the recalls by Lenovo.
Any idea if there's any option but buying a new battery? It just does not seem right that the battery is unusable after new OS setup.

Battery does not charge, IdeaPad B590, call center is dead

At 23th December, 2013, the battery of my sons IdeaPad B59 notebook went Wrong. It does not charge. The lates update of the Lenovo softwares are installed, but it gives error messages.
I tried to call the local service center, but it does not answer. After 10-15 minutes of the mucic from the call center pfone (tried today several times!) I give up.
Does it exist ANY working contact with the local (Hungary, Budapest) Lenovo service people?
I bought the IdeaPad B590 laptop on 24.07.2013 in Budapest, and have a (possibly) valid warranty for it.
Any prompt solution?

My iPad is not charging properly

hi,
my iPad is not charging properly
regards
saravanan

saravanan,
There aren't too many things that prevent an iPad from charging. First be sure you are using the charger that came with the iPad and you have that plugged into a good wall outlet.
1. Bad charger. Test by using a different Apple or name brand charger designed for iPads.
2. Bad cable. Test by using a different Apple or name brand cable. Don't rely on cheap cables and chargers purchased at your local mini mart.
3. Dirt, lint or fuzz in the connection port. Inspect and carefully clean if necessary.
4. Software failure. Reset the iPad. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.
5. Hardware or battery failure. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

That does happen. It depends on how hard the server is being hit, as well as the connection speed of your system. If you are on a windows system, you will want to disable any antivirus or firewall software during the download.

U300 Touchpad Driver for Windows 8 Does Not Load Properly

I have spent a few hours with both Microsoft Premier Technical Support and (a very grumpy) Lenovo technician. They have both confirmed that the Windows 8 touchpad driver that is currently posted on the Lenovo site for the U300S does not load properly. It will, as many have reported, disable the touchpad altogether. There seems to be an issue with the loader installing files for both a Synaptics and a Cypress touchpad. This creates an apparent conflict that relegates the touchpad as useless.
If you choose to install this driver, I would recommend that you create a store point so that it can be easily recovered.
A standard mouse works just fine (albeit without any Win8 functionality).
***Lenovo should pull this damaging driver down from their site until a certified replacement can be prepared.***

W530 battery does not charge

Hi,
I have just got a new W530 (2436CTO) with the battery (70+?), BIOS ver is 1.07. The battery does not charge even I plugged in the AC. The battery status is ok and charging on the power control panel, but there is no estimated charging time and the level has been at 4%. I have changed all types of battery control profiles but that does not work. I have even followed another fellow's example and updated in the display card, but that does not work either. I have updated every possible thing except for the BIOS of the laptop, which requires a fully charged battery to update. I hope someone who has similar experience can give me some pointers.
Thanks!
Fai

'afternoon.
the 70-series battery is correct for your machine. since it's new, i would call Service:
http://support.lenovo.com/en_US/detail.page?DocID=PD008370 and ask them if they'll send you a replacement battery.
if a new battery fails to charge, then it could be something amiss with the charging circuitry in the laptop, but best to take one step at a time.
regards.

IPhone 3GS no longer recognized in iTunes and does not charge via wall

I upgraded my iMac to iTunes 9.2 when it came out.
My wife then upgraded her iPhone 3GS to iOS4.
Since then it is not recognized in iTunes and does not charge via the wall adapter.
I realize this topic crosses over with several ongoing discussions, but there are no 3rd party peripherals involved here.
The only major changes to our set up have been the itunes and iOS upgrades.
The battery is running down, any ideas to fix this, or other similar experiences welcome.

Went to the Apple store and they replaced the cable.
