I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Hello, I downgraded my OS from Win 10 to Win 8. It seems like I couldn't get all the drivers updated because there aren't too many drivers available for Win 8 on the support page. The most noticeable problem to my labtop is that I cannot change the brightness of the laptop as well as the airplane mode. Whenever I press on the key F11, 12, and 6, it doesn't do anything. Is there a driver available for download online? Thanks.

Help pls i upgraded my ideapad 100 from windows 8.1 to windows 10 and since then anytime i startup the system from shutdown the brightnes control becomes inverse(ie increasing the brightness reduces the screen brightness and vice versa) but if i restart the system it works normally and also if i disable and enable the Intel HD graphics from device manager it works properly.But since i will be using the shut down and startup option more frequently than the restart i dont know if there is any fix for this.

I just purchased this new laptop a couple of days ago and love it other than one thing that is annoying the crap out of me. The screen is too dim when unplugged. It is great when plugged in, but dims quite a bit when it is not. I have the brightness at 100% for both the on battery and plugged in settings so I have no idea how they vary so much. I have it set for high performance, not power saver. The battery saver is also off. I have looked all over the internet and found no useful info.

Hi Sam,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to hear that brightness functionality is not working as expected in your Z400 Laptop; I suggest you to install LEM (Lenovo Energy Management) and the latest display drivers in the computer according to the relevant OS (Operating System) installed. Below are the links to download the relevant display driver:
 

Intel Video Driver for Windows 8.1(32-bit  or  64-bit)
Nvidia Video Driver for Windows 8.1(32-bit  or  64-bit)
Lenovo Power Management for Windows 8.1(32-bit, 64-bit)

Hope this helps!!!
 
Do post us back if the issue persists.

I have a new Lenovo Ideapad 310-15abr, Windows 10, 64 bit, AMD with a Radeon 7 graphics card, with a display problem. When I unplug the power (so it's on battery), the screen dims. So I went to Power Options and changed the power plan both on and off battery so the screen is at 100 percent brightness. Didn't work. Tried a Custom Plan and then went back to a High Performance plan. I turned off Adaptive brightness; disabled the Sensor Monitoring service; updated the Graphic Card driver;disabled and then enabled the Graphic Card again. Turned off Lenovo's Power Options called Power Stretch and Conservation mode.  Also updated the AMD VGA driver.  Nothing works. Still dim when on battery. One thing that I have NOT triedit is changing the registry value by using Regedit command and changing the Feature Test Control. I didn't try it for two reasons. One is that I'm not sure what to reset it to (I've seen "ffff" as the setting and something else longer and more complicated). The other reason is that I am too much of a dumbie to be messing with registry values, basically. I've seen this question asked a couple of times, but no very definitive answers. People usually just tell you to change the Power and Sleep settings so the brightness is on 100% when On Battery.  So that answer is not necessary, but ANY OTHER ANSWERS would be welcome!  Thanks -- Ken

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. Can someone please help with how to up the brightness?

Hello, I recently had a downgrade from windows 8 to 7 in my Ideapad s300 (intel i3) and I noticed that display's brightness is very dimmer than when I was using windows 8.I tried almost everything, the brightness is actually adjustable, but the maximum value is still much dimmer than it was on 8, I tried both intel's latest drivers  for the intel hd 3000 graphics card and the official lenovo ones but this didn't solve the issue.I read in other topics that the problem can be solved by updating the bios.The problem is that there's no BIOS update on my support page for this model\product, and the only one I found is for the s400 model, which I am not sure it could work or either cause some serious troubles.At the moment I have almost everything installed from the lenovo support site, including vga, chipset, energy management etc.I saw another thread that suggested to upgrade the bios but there's nothing about it on the support page, apart from a link to an external download claiming its fot a s400 model, so i'm not sure.Can someone help me? What should I do? Is there an official bios update for my product? Can you be so kind to share it with me?

So everything has been working fine on my laptop until about 10:30PM EST tonight. I bought it new in August 2011.
Specs:
 
OS: Windows 7 Home Premium
CPU: Intel Core i7-2630QM @ 2.00 GHz
RAM: 8 GB
HD: 750 GB
BIOS: 45CN36WW
 
It's always been a fine machine with NO problems.
However, last night there were Windows 7 updates that were installed and then restarted my computer. I had not gotten a chance to check exactly what they were though. About 10:30 this evening, flash crashed in Mozilla Firefox which is not that uncommon, and from there Firefox closed, and so did my Microsoft Word and Excel apps that were open. From there, my computer began to shut down and restart. When it went to restart, all it could do was go to the opening Lenovo screen which gives you the F2 (setup option) and F12 (multiboot menu option) as it typically does. Besides a thin strip at the top that appeared after about 30 secs that only displays moving static that eventually will just stick, that is where the boot process ends. No Windows 7 screen, and certainly no opportunity to boot into safe mode to check for any problems. The screen freezes and goes nowhere.
 
So basically, all I'm getting in terms of boot options are lenovo features, not windows 7 features, meaning it won't boot into windows 7 or windows 7 safe mode no matter what I try. The biggest problem here is that I have no windows 7 disc to even try to boot from my dvd drive.
 
Anybody have any suggestions on what the probl... Read more

I am totally disappointed in Lenovo's customer support. My lenovo 710s was bought less than 1 year ago (as of 10/6/2017, when I sent it in for repairs) and had 2 years warranty (1+1 year of extended warranty). I sent my laptop for repair due to a white spot issue on the monitor, affecting viewing of webpages and videos. However, the laptop was returned after 3 weeks without any fixes/repairs, as Lenovo claimed that it was a cosmetic issue. I wrote a message on their customer care website on 3/7/2017. However, they ignored me and there was no reply to date.  I thought Lenovo is a reliable and popular brand. However, it turned out to be a horrible decision, much to my dismay!

Hi! I have seen a few other posts on here about havig issues with the brightness changing and have looked to them first before writing my own post. I have made sure that Enable Dynamic Brightness is turned off under the Lenovo Vantage settings and I have Change brightness automatically turned off under my system settings, but I can still still see my brightness changing when I change from light to dark backgrounds and it is getting VERY annoying. It makes reading, or doing anything on the computer for that matter, very difficult and I can't figure out why it keeps changing when I have everything turned off. I have also checked to make sure none of the drivers need updating but they are all updated and have rebooted my computer multiple times. Is anyone else having this issue or does anyone know why this is still happening?? Thanks!

Hello! I am new to Lenovo and picked up my 1st laptop yesterday when my HP died. I have always had HP and grew tired of how easy they break & poor battery life, so I wanted to try a different band. I love the computer, the keyboard, track pad & screen are amazing. I bought the ideapad 320-15IAP for about $330 (Including tax) The specs at the store advertised 4.5-5 Hours of battery life, but I have not been able to get a charge better than 2 hours. For someone that uses my laptop at work and on the go, this will not do. Can any one offer up any advice? Does lenovo sell stronger batteries for ideapad that I can replace with this current battery?  My next issue is the Windows 10 update that you are forced to do, I have been trying to install it since 9PM last night, it is now 9PM tonight, a full 24 hours, and it has not fully installed. I have done my fair share of google searches and many people have had these same issues too, but no good solutions outside of deep computer hacking, I don't want to have to do that on a brand new computer. Thanks for any and all help!
