I open this post to report a brightness problem on Lenovo Z500 Ideapad. Yesterday I've upgraded to OS Windows 8.1 and when I adjusted the screen brightness it goes off, and brightness adjust function doesn't works. I've solved my problem reinstalling the Intel video drivers, downloaded from Lenovo Driver Support.
It seems that Windows 8.1 upgrade disables video drivers.
I own an Ideapad Z-500 notebook running Win 8.1.After updating Intel graphic adapter from Windows Update the screen brightness adjust key (F11 and F12) stops working and I cannot adjust my scrren brightness.I have to uninstall it and disable Windows update to keep using my laptop.
Here are driver details.
Name: Intel Corporation - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3 - Intel(R) HD Graphics 4000

I can't adjust brightness ....
View 3 Replies View RelatedI have a new z500 that I've downgraded to Windows 7 64bit. For the most part I have everything working. I accidentally hit the brightness + (yes, +) and it instantly dimmed the screen to where it is barely viewable. It seems that hitting that one key decreased the brightness to the minimum amount. I've rebooted, looked for a setting in the BIOS, hit the Brightness +/- and can't increase the brightness. It is interesting because the other hot keys work correctly. I've even upped the brightness in the Control Panel, but nothing seems to work. The screen is extremely dim whenever the machine is powered on (including the BIOS), not just in Windows. I tried a lot of intel chipset drivers, the available Intel HD 4000 drivers in Win8 and win7 too, but nothing working. How to up the brightness?

View 9 Replies View RelatedThe default behavior of F1 through F12 keys on the z500 are set to perform laptop functions like mute, turn sound or brightness up and down and so on.
Is there a way to reverse the way F1, F2.. F12 keys work, so they work like on any other regular keyboard.
I use the basic functionality of the F-keys all the time, when renaming files, searching and so on, and I would like to be able to use them without having to press "fn" every time.
I bought the Lenovo Ideapad Z500 and I'm trying to boot from a USB drive in order to install Windows on it. When I start the boot menu I only see the hard-drive, the DVD and the network. I tried to set both UEFI mode and Legacy mode in BIOS but the USB stick does not appear in the menu when I boot. I put the image of windows with Windows 7 USB DVD Download Tool which formats the stick in NTFS mode.
I have the latest BIOS v1.21 and I tried with 2 different USB sticks: one 16GB USB 2.0 Corsair and with a 32GB USB 3.0 ADATA both on USB 3.0 and USB 2.0 ports on the notebook. I really haven't seen anything like this in my entire career.
I even downloaded the file efiootBOOTX64.efi and replaced the one that Windows come with on the specified folder on the USB stick ....
Why is so difficult to choose the USB boot drive on the newer notebooks? How can I boot from USB?
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.
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've a problem with my Z500 (i5/8gb/GeForce 740/1tb)
Its HDD makes clicking sound all the time. Its really annoying.
I would like to know is it normal?
All was fine until I pressed F12. Now even on maximum brightness it's really dim.

My battery is at locked at 59% of charge and even if i connect the power plug it doesn't charge any more.
I had the same problem a few months ago and I run run the "Battery Firmware Update" i found here: [URL] ....
It worked for then, but now I have the same problem once again and firmware update doesnt work anymore because my firmware is already up to date.
My z500 cannot boot up without power cable plugged in. Usually,a few seconds after I saw the lenovo logo,the system will suddenly shut down just like the battery was removed.however,if I connect powercable to the laptop and power on,everything is fine,I can enter windows 8,or ubuntu,after I enter OS,I can disconnect the power cable without any problems.the battery is healthy and can last for more than 2 hours.
So far I tried the following methods:
1.update BIOS
2.update battery firmware
3.reset BIOS
none of them worked for me....

View 9 Replies View RelatedI have an Ideapad Z500 with an W8.1 installed on it. I updated the bios to the last version but after that I can not control the luminosity level anymore. When I try to do it pressing the Hotkey it trurns to the lowest level of luminosity and I can only fix it by pressing the hotfix key when the laptop starts. I can not return to the old bios version. What shall I do?

The Brightness funtion Key is not working. But other function keys are working Properly...
I have an ideapad z500 which I'm happy for, but it annoys me that when 'm at my college I can't properly connect to the wi-fi the school has. When I connect, I'm on for usually about half an hour, but then I get the "limited connection" yellow triangle and I have to deactivate the networkcard before I can get a normal connection.
Other times I simply just can't connect, it tries but it fails. When it does, I have to reboot the computer before it succeeds, and that's no good when you are working on a project. At home i have no problems, it works nicely.
Also, how to enable the WiDi on the z500.
My PC is running Win 8 with the Intel Centrino n2230, Intel 3rd. gen i7 (3632qm)
I started using my laptop with Windows 8 and everything was working fine. But then Windows upgraded to 8.1 and now I cannot get the Dolby Home Theater v4 to start, I always get the error message about driver.
View 2 Replies View RelatedI can't adjust screen brightness using either function key or in control panel. Using the function key the little panel of brightness volume shows up on the screen but does nothing. And in control panel, through either the bottom brightness scroll or the power option won't change anything. Only time when the brightness will change is I unplug the power, but in the power settings it won't let me change/adjust the brightness.
And what is the battery function key for? I press it and it does nothing. XPS L521x

Purchased from Amazon 2 months ago and worked perfectly without a hitch until a few days ago when I got on the receiving end of the win8 equivalent of the BSOD with the . From them on I ended up with slow boots random pauses etc. I opted to refresh the PC without affecting any files but toward the end of the reinstall the BSOD appears and now all I had was a black background with only a white cursor.
Left that for over a hour, nothing happened so held down the power button to force shutdown. Found that Z500 no longer boots into win8 so eventually decided to do a clean reinstall with the onekeyrecovery via NOVO button. This should have been the end of all the problem I was having but unbelievably the problem is still there.
Research what I could about this and found that the slow boot is caused by hard disk constantly being thrashed about by a system file ntoskrnl.exe. I tried updating the wifi driver and it appeared to have done the trick until the next day when I booted up the system again. It appear that the constant hd activity goes away after a few hours of leaving the PC on.
Anyway I have drawn a blank as to what's going on especially as everything was working perfectly until up to that point with no signs of system conflict.
I can't adjust or change my brightness with the hotkey (F11 and F12) or even with the slider in settings. option brightness of my laptop doesn"t change it is stationary.
View 5 Replies View RelatedI 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.

I recently installed a new hard drive and installed windows 7 pro 64 (previously on the other hard drive was Windows 8.1 Pro 64 bit ( there I could change the brightness ) )
My problem is that I can not change the brightness .

-Reinstalled all Intel graphic drivers new
-Reinstalled Intel and Nvidia drivers simultaneously

I recently purchased an Ideapad P400, and I have noticed that the default for the keys where F1 and F2, etc. usually are, are now the mute and volume buttons. To access the F1, F2....F12 keys, you now have to press Fn + your desired F key.
While I understand many people probably find this useful, I play several games where these keys are essential, and it makes playing the games nearly impossible to play if you have to hold down the Fn key in addition to the desired F key. So my question is, is it possible to reverse the Function keys? I would much rather press Fn + F1 to mute than have to press press Fn + F1 to access F1.

View 9 Replies View RelatedMy fairly new Lenovo Y410p funtions extremely well when playing a video game, but only when connected to a charger, as soon as I disconnect the charger, my framerate can drop to upto 1/8th of the original framerate. It is always connected to the NVidia Graphics Card, the power plan is always on high performance, and the minimum processor state on battery for the processor power management is 100%. How I can fix it? Am I missing something fairly obvious, or is there a defect with my computer?
