Lenovo P/Y/Z Series :: IdeaPad Z500 Brightness Can't Increase
Nov 24, 2012
I 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?

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 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 own an Ideapad Z-500 notebook with Win 8.1 pro.
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....

I 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?

I have trouble with my audio driver on my lenovo laptop. After I updated BIOS to version 1.21, my sound stopped working. I tried to reinstall audio driver, but when I reboot my computer, sound is not working again.
I read about flashing BIOS back, but I dont know where to download old version.

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)

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 have z500. I start playing some medium grapic games. After a 1 hour gameplay my graphics start to glitch so i checked my cpu and gpu temp. I saw that CPU temp has reached 99 Celcius but still the fans were dead.
Few minutes later, after what ever reason, fans start to spin and now its cooled downed to 60 C. and keeps spinning in low speed still.
Since i can see the temp, i assume there is no problem in thermometer so i assume its kind of a software deficiency. I am not using any overcload or cooling app, my power settings are set to high performance.

I recently got the Z500, working under Windows 8.I got a question regarding the battery charge. I work on the laptop for extended periods of time with the power plugged in. Since this is bad for the battery, is there any way to disable the charging or to perhaps remove the battery?I wasn't able to find anything similar for this model.

Ever since I got the laptop over a year ago, the audio was never working properly for me. Every time a sound was played there would be a staticky sound played with the audio.
The same thing happens when I use headphones with it. The laptop is also out of warranty so I don't know what to do.

I bought Z500 last week and I am facing problem with the battery life. I charged the laptop for 12 hr for the first time. The battery discharges within 2 hr every time. I just browse internet or watch movies and the battery life is far below the expectation.
There are two power plans - Balanced and Power saver and I do not see any difference in either. What is wrong with my laptop battery.

The 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.
