Lenovo B / G Series :: G500s Touch Screen Random Inputs And Appears Contextual Menu Without Touching
Oct 29, 2014
I'm experiencing a problem with my G500s Touch, i am not touching the screen but it makes a lot of random inputs and appears contextual menu (like right click). It's really annoying, one of these days i'm going to throw this laptop through my apartment's window.
Â
I already opened device manager and deleted all HID interfaces and reinstalled. Reinstalled Elan Drivers (i think maybe it is the problem, elan driver), i used windows restore 3 times and i still have the problem.
A Quick solution for this: Ctrl + Alt + Del, then Escape. And you will not have this problem in the next 1, 3, 5 or 10 minutes.

I just bought a Lenovo G500s touch and the touch-screen initially worked though I had rebooted a few times after the screen appeared to freeze. Â Now you cannot use the touch-screen at all...

I've got a X230 with an IPS screen since 1,5 years, and I currently have some issues with it.
Sometimes, the bottom left of the screen blink and black bars appears, along with some square brightness shapes.
I'm pretty bad to description, so here an album of the problem : [URL] ..... (it's more clear if you zoom).

This is a detail of the bottom left :

Again, this appear sometimes only, and a knock in the screen resolve the problem, but it's worrying.

I had lenovo g500s recently with windows8 64bit preloaded. I got bored from windows8 and downgraded to windows7 home premium 64bit (a difficult procedure by the way)....
Â
Windows 7 worked very fine after installing the device drivers, except for the LCD brightness that doesnt respond to any fine adjustments...
Â
In the main page of windows power management, as well as the keyboard hotkeys, the slider either goes to the maximum or minimum brightness (no stages in between though in windows 8 there were > 6 stages)....
In the advanced settings screen, as far as i adjust brightness (for example to 50% on battery, 70% plugged in) this doesnt lead to any change in the brightness practically....

Random Black Screens and Random Sleeping: [URL] ...

Black Screen: [URL] ...

I thought before maybe its Bluetooth related as sometimes when screen would turn black and then come back, I would get a 'Bluetooth Device Not Discoverable'. So turned off Bluetooth in the BIOS, but still having display/sleep issues.
I removed hte Lenovo Power Manager/PM Driver, and turned off sleeping in the Windows power settings (in every setting including if Low Battery Action).

I've have had a Lenovo g500s running windows 8.1 for almost a year and never had an major issue. But recently I have found that it will not turn on. I have found that by taking out and putting the battery back in will rarely result in the battery light blinking in red. If i try to turn it on at this point it will turn for a few second "prepare for automatic repairs" and then in a few seconds turn back off its original turned off state. I have tried "Flee-Power" while calling technical support and it made a small noise and then issued a burning smell. It's 1 year warranty is still valid.

I have a problem with my Lenovo G500s 1.1 years (1 year & 1 month). It worked perfectly until last month. It started to freeze. I restarted the computer (btw I was using licenced win8 back then) and then the lenovo logo showed up and it stuck there. I was waiting for about 10 minutes, but nothing happened. I turned it off manually, and then turned it on,it was still frozen. after some trial of startup, it worked normally. After 2 days it happened again. I thought it was the system, so I deleted the windows8 and installed windows8.1 licensed, it worked for a month and then again (last night) it just freezes at startup (lenovo logo shows up). Till now its frozen. I restarted it several times, it didnt work. I also pulled out battery & started on AC power which didnt work too. Obviously, i dont have warranty.

my brand new lenovo y50 touch. Straight out of the box, everything works beautifully except one major thing: the touch screen doesn't work. I know it is the touch version and settings even calls it "lenovo y50-70 touch" but below that it reads "No pen or touch input available for this display" ...what?? there are also no drivers on lenovo's support page that say anything about touch.

I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again.

Windows doesn't recognize that my U530 Touch Laptop has a touch screen. Worked okay for the first couple of months. I've tried looking for hardware updates and restarting. Computer is only a few months old, so this stinks.

My laptop's touch screen function stopped working just a while ago. When I shut down my laptop, tere's this windows update that lasted for more or less an hour. After that, the touch screen just stopped working. Note that there hasn't been any program installation prior to the antivirus uninstallation - all programs and files contained in the laptop is as it was the moment I bought it. *Laptop's running Windows 8 Single Language

I have received 3 of the above model ultrabooks, Windows 8 installed but the touch screen will not work at all. This needs to function.
Â
Does this model support touch screen and if so, how is it enabled. OS fully patched. Pen and Touch seems to be enabled but no response to tests.

I just got my new carbon touch thinkpad today, and I couldn't be happier, until I closed the lid and reopened it a couple of minutes later. The screen froze for a while and then I got a BSOD with the notice CRITICAL_PROCESS_DIED. I hoped it would be just some coincidence, and updating my drivers and installing windows updates would solve it. So I did, and closed the lid again. After reopening it, I got the same error. So I figured I could just as well restore to my factory settings. Without luck. After updating everything for a second time, still no luck. I check the disk and did a memory check, but everything seems fine. The lenovo Solution center isn't reporting any issues either. I looked into the minidump created by the blue screen, and it seemed the process failing is called csrss.exe.

When I put my X220T in tablet mode, the screen moves just enough to move the pointing stick in the middle of the keyboard to cause the cursor to move. I can't rest my hand on the screen without causing the cursor to move all the way accross the screen.
Â
Am I missing a driver that would disable the nub when the screen is turned over it, or is this a design oversight? I've got the latest BIOS.

I have bought Lenovo Essential G580 (59-324061) Laptop (3rd Gen Ci5/ 4GB/ 500GB/ DOS) on Feb 2013, its out of warranty now.
Â
I have installed Ubuntu in the laptop, not sure how i formatted the hard disk during installation. I guess it was full format of hard disk during installation (while selecting hard disk).
Â
Till today everything was working fine. From today morning, there is always a Boot menu which is being displayed with following options:
1. ubuntu
2. PCI LAN: Atheros Boot Agent
3. ATA HDD: ST500LT012-9WS142
4. ATAPI CD: MAT**bleep**A DVD-RAM UJ8D1
Â
I have pressed enter in both Ubuntu and ATA HDD options. But after a brief duration the control comes back to the same menu I have specified before. How to boot to ubuntu.

My computer doesn't seem to start up anymore. It only enters the "Boot menu" tab with no further information. When I'm trying to press "Enter" it just returns back to same screen again. Is my harddrive broken? Is there some reset button available anywhere on the device?

The day before yesterday I bought a new Lenovo IdeaPad U330p without operating system. I already installed Windows 7 Ultimate 64 bit, Microsoft Office 2013 and some drivers.
Yesterday everything worked properly, but since today there's always a bluetooth symbol appearing (approximately) every 20 sec) on the right side of the screen. It disappears immediately.
It is not possible to click on the symbol, it still disappears.
Â
I already tried to uninstall the Bluetooth-driver, but it didn't work. After restart they are reinstalled automatically.

I've recently reset my laptop to factory default using the Windows 8 Reset option, and now when I want to access the UEFI settings I get a onekey recovery prompt instead. Is there any way to bypass it because I just transfered my files back and I don't want to reset everything again.

I have the following problem with my computer, lenovo sl 510: when pressing the power button, the computer won´t boot. On the display you can see a black background, in the upper right corner the intel emblem and in the lower left corner you can see "thinkpad". I cannot enter the bios and nothing works. We´ve tried already to press the power button a few times to reset the computer. Didn´t work as well. The keyboard doesn´t accept any hot key combinations.

There is an image of a black square with an up arrow on the lower right corner of my screen. Sometimes it has a line though it.

my laptop started acting REALLY weird about a week ago. While I am using it, seemingly at random, the screen 'flickers' and freezes up, and the only way out is to hold the power button to shut down, and then restart.
I have included a picture of what it looks like:
I also noticed that the speakers sort of emitted a 'staticky' sound as this happened, although this could just be because the computer stops processing the sound data.
Anyone ever experience anything similar??? What to do?
Also if I check the Windows Event Viewer after restarting, it logs nothing at the time of freezing, no errors or anything.
The laptop runs sort of warm, but never part 66°-69°C
It has: Windows Vista SP1, AMD ATHLON X2 1.6, and 2gb ram.
