Hi
Welcome To Lenovo Community
We are really sorry to hear about the issue you are facing,
Please check if you uninstall the drivers for touchpad and then restart the system to check if it works when AC adaptor is connected
Also try the drivers from the below link after uninstallation of current drivers

HP Spectre XT 2050nr - Doesnt work unless plugged in

Hi guys,
My computer doesnt work unless plugged in. The tech support helped me uninstall and reinstall the battery, update bios and check for errors. Everything passed. It still dies when unplugged, instantly. It will not boot unless plugged in. The battery reads 98% charged 24/7.
Any other solutions?

How old is it? The battery is a warranted item and it looks like, most likely, the battery has died.

There is a hardware problem. Whether it's worth it to you to have no working phone for 2 months until you can update vs paying for replacement/repair now is a question only you can answer.

My Ipod touch will only work when plugged into a itouch radio. When I take it out, it goes blank. Why can I do?

My Ipod touch will only work when plugged into an Itouch radio. When I take it out of the charger, it goes blank. The battery shows fully charged. It appears that the battery is no longer charging. What should I do?

Try a reset: Hold the home and power buttons at the same time until the Apple boot logo appears. No data will be lost. If that fails, the battery may have gone kaput.

Have you recharge your iPod for at least 2 hours, preferably till the Full charge Battery symbol comes ON.?

Is there anyway to have an 11 inch mac air connected to an external monitor with lid closed and still be able to see content. I have a wireless ketboard and mouse and have tried everything. Only works when plugged in.

You are referring to a feature called Clamshell Mode, please read Clamshell Mode setup for instructions.
BTW when posting when you use generalities such as "have tried everything" this tells us nothing. When posting please be specific and try to paint a complete picture. It just makes things easier for those trying to help you.

Reset the phone then try it again: hold down the home button along with the sleep/wake button until you see the apple, then let go.

Why this path doesnt work when there is "!DOCTYPE" element?

Hi, I need to extract contents from an xml file, which looks like
<hr />
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article PUBLIC "-//ES//DTD journal article DTD version 5.0.1//EN//XML" "xyz501.dtd" > 
<article docsubtype="fla">
<item-info>
<jid>YANBE</jid>
<aid>12941</aid>
</item-info>
</article>
<hr />
And I have tested with this path "//article/item-info/jid/text()", but it doesnt give me anything. But I noticed that when I remove line 1, it does extract the content "YANBE"...
why the path doesnt work when there is that DOCYTYPE element? How should I get around with this please?
Many thanks!

The extract of XML you gave is not valid (Line 1: <hr/>) but besides that ... I think your problem is in the DTD.
Somewhere in the DTD it probably 'sneakily' defines a default attribute which in reality is a default-namespace for one of the elements. This means that in your XPath handling, you will have to map a prefix to a namespace-uri (NamespaceContext [1]) and use this newly defined prefix in your XPath expression.

My time capsule doesnt work when its conneted direct cable modem, and it start working from netgear router

I just bought a Airport Time Capsule, time capsule is connected direct from wan to cable modem (it doesnt work). when i connect it to lan port 1, it start working. normal process i know is from cable modem to wan port. 2nd i notice, network is on bridge mode. so my question is how do i make it to work from modem to wan port.

What model is the modem? Is it a pure cable modem or a combined modem router?
This maybe important as the current model TC does have issues with some of the popular cable modems.. SB6121 or 6141 being often the ones complained about here.
If it is a pure cable modem (most will have just one ethernet port). Then power down the modem for 20min. This allows enough time for the MAC address of the first device connected to be lost at the ISP end so it is ready for a new router.
The TC must be in dhcp and nat mode.
Please factory reset the TC and start over.
The Factory Reset universal
Unplug your TC/AE. Hold in reset. and power the TC/AE back on.. all without releasing reset and keep holding in for about 10sec. The time is not important.. it is the front LED rapid flashing that indicates you are in factory mode.
Release reset.
If it doesn’t flash rapidly you have released reset at some point and try again.
Be Gentle! Feel the switch click on. It has a positive feel.. add no more pressure after that.
TC/AE will reboot after a couple of minutes with default factory settings and will wipe out previous configurations.
No files are deleted on the hard disk.. No reset of the TC deletes files.. to do that you use erase from the airport utility.
By default the TC is in router mode after a reset.
Restart the modem.
The power up the TC and run through the setup utility.
The TC should then be accepted as the main router in the network.
If this fails check the WAN ip address. If it is 10.x.x.x or some other private IP you did not turn off the cable modem for long enough.. Try again only this time leave it off longer. (Some ISP it is just 5min.. some 15.. some will require 60min or overnight).

Touch Screen not working when plugged in via usb to laptop

I am hoping someone can help me figure out what to do because I have run out of ideas... When I plug the phone into my laptop via the USB cable provided with the phone (2006 Dell 1710 Inspiron, Windows Vista) the touch screen does not work. The phone is functioning but I just can't use the touch screen to do anything, more specifically, I want to connect as a mass storage device so I can transfer files, music, pictures, etc.
I have downloaded the drives, installed and reinstalled the drivers, soft rest, used all 5 USB ports on the laptop and made sure the ports were up to date for drivers and software on the laptop. Still the screen won't work when plugged in.
My next step was to try it on a different computer so I used an HP desktop running Windows 7. Downloaded the drivers when prompted and low and behold the screen worked just fine when plugged in. It also works when plugged into my computer at work.
Considering the phone works fine on another computer I am guessing it might be the USB ports on my laptop or the software associated with it.
If anyone can help I would greatly appreciate it. Thank you!

I would definitely agree with you, Funkytown. If we know the phone works properly with two other computers and you've run through all the troubleshooting (awesome job!), then we can determine there is something with the computer that is causing the issue.
Thank you!

Only works when plugged in

My iPad 2 was left on overnight, not plugged in with the battery at 95% last I checked. This morning it was off and I was unable to turn it on. I plugged it into the charger and it seemed to start up, but the date and time had been reset to December 31st 1969 at 4pm!!! Then, I tried to reset the date and time but it would automatically keep going back to that date. When I went to unplug it, so I could sync it with iTunes, it turned off immediately! It only works when plugged into the charger and even then it turned itself off after about 2 minutes. While unplugged, I tried a hard reset (holding the home and sleep/wake button down at same time for 15 seconds, but it doesn't do anything at all. I did notice that it was pretty hot yesterday, but didn't have any problems running it at all. Any suggestions, or is this clearly a hardware problem? Thanks in advance.

When it was plugged in, it was at 95% so that's not the issue. THe battery appears charged, but the device simply doesn't want to run on it. The weird date reset makes me think it could potentially be a software issue, but I'm worried it is essentially a hardware/battery problem.

HEADPHONES do not work when plugged in - iMac Intel

So I reinstalled the operating system a few months back. After completing this my headphones do not work when plugged in. I do have them plugged into the correct jack. When i plug them in the built-in speakers go silent for a second or two as if the headphones are working but then the speakers kick back in with no sound in the headphones.
The headphones worked just prior to reinstall so I'm not sure its the jack itself but something in the operating system.
I have also checked in System Preferences 'Sound' and when they are plugged in, they do not show in the devices window.
What the heck is going on? I've read in other forums that this seems to be something of a typical problem but have not found a solution to the problem.
thanks in advance for your help.

Welcome to the discussions.
Mate, it sounds more like a system glitch than a hardware issue. I too have been experiences some 'funky' issues. However, they have all been fixed by running Onyx disc maintenance software. Install Onyx and run 'automation'. You can cancel the disc checking operations on start up and ignore the back up disclaimer. Give it a go and post back with the results.

Make sure you get the right version for your OS.

My iPod only works when plugged into a wall socket!

Anyone know why my iPOD only works when plugged into a wall outlet? I tried it on the Bose docking station and also my MacBook and it won't work!
Any ideas??

Sounds like a dead battery. You can have Apple swap out the battery for a flat fee or you can send it to a third party service center to have them do the same for job a little less.

Classic iPod not charging; only works when plugged in

My iPod Classic would work only when plugged in my computer or to the wall. I noticed that when I plug it, the battery automatically turns green and the fully-charged symbol appear. However, when I unplug it, it doesn't work. Any ideas on what I can do? It's no longer under gaurantee so anything that I can do at home would be helpful. Thank you xx

Seems very unlikely you need a new Macbook since it works when "plugged in"; at worst you will have to spring for a new battery.
Try running this program - it will give you info about the state of the battery:
