For some reason I can't change my screen brightness anymore. I've already tried a HD 4000 driver rollback to version 9.17.10.3223 and I also disabled "adaptive screen brightness" at the power management. For some reason I can change the brightness by using the "microsoft basic display adapter" driver instead of the HD 4000 but that isn't a real solution.

I have already checked:
1) Changing regiser's key as above/;
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesstorahci Start 3 -> 0
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesiaStorA Start 0
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesiaStorV Start 0
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesstorahci Error Control 3 -> 0
Unfortunately after rebooting in RAID mode, OS doesn't work.
2) Going step by step over the description made by microsoft support team: [URL] .....
Doesn't work.
My aim is to configure my SSD as a cache drive and as I read - without changing mode into RAID, it wouldn't work.
Maybe there is a possibility to set up SSD as cache in AHCI mode?
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 3 Replies View RelatedI have had my laptop for over a year, and after upgrading various drivers in an attempt to fix a random power off issue, have now found that the laptop will BSOD everytime I wake it from sleep.
I am running Windows 8.1
The root cause seems to be that the SSD no longer appears in the BIOS, therefore I am unable to re-install the Intel Rapid Start software and enable RAID which seems to be a requirement.
My BIOS version is 65CN97WW dated 29/01/2013
This is what I see using DISKPART
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt

There is definitely an SSD in the laptop.
Can this be fixed with a BIOS update?
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.
View 9 Replies View RelatedMy lenovo G505 recently had to be reformated because there was a blue screen that came up one day that said there was problem with my PC and the error was critical_service_error, something like that. So my dad had to reinstall windows 8 for me using a cd he had that didn't come with the computer I don't believe. So now for some reason my screen brightness isn't adjusting and it's driving me crazy! It's staying on full brightness which I hate! I tried changing it from the personalization screen and nothing happens.
View 3 Replies View RelatedWhen plugged into the adapter my Levovo Z570 screen flickers between bright and dark when on certain webpages or doing certain tasks. I have changed the battery and this makes no difference. This doesnt happen when on battery power.
Note that the brightness is flicking between the battery brightness setting and plugged in brightness setting. So if there is a large difference between the two the flickering is very noticable and distracting. If I make the battery brightness the same as the plugged in brightness the flickering doesnt happen.

My problem is that I can not change the brightness .
I've already tried:
-Reinstalled all NVIDIA driver
-Reinstalled all Intel graphic drivers new
-Reinstalled Intel and Nvidia drivers simultaneously
-Remove Lenovo Power management
-Tried to install NVIDIA driver from the Lenovo and the Nvidia page
-Reinstalled Windows

I got this idela pad U410 about a year ago and it was functioning nornally. A few months ago it started to boot up very slowly when power cycles. A hibernate was quick. Now it never comes up and keeps waiting at the Lenovo screen, no windows. I have seen posts that say it is a manufacturing defect. This one is out of warranty, so what is the solution. Do we have a solution at all? Why does Lenovo market such a bad product. BTW, the back cover is so flimsy that it gave up and had to replace it. Overall a case of bad engineering i guess.

I bought a dv3t-2000 two months ago and recently i installed windows 7 and i just realize that is not possible to change the brightness on the screen, is always the same. I have tried changing the power plans, I've upgraded the BIOS, but so far is not working.
View 9 Replies View RelatedI have a Lenovo U410 and a set of USB speakers on a faulty USB cable. I know, my fault: i connected the cable and the "+" and "-" connected for a short time. In my laptop i heard a little electrical explosion (no smell) and the laptop immediately powered off itself. At once i removed the USB cable and switched the laptop back on: no problems (!). But once booted, no USB port was working anymore. So my conclusion: i "fried" the system board somewhere.
The laptop is in its guarantee period, however i removed the hard drive and replaced it with an SSD. I assume the guarantee is lost when i replaced the HDD. I just re-opened the casing but i am unable to find "fried" components or "burned" areas.
Questions:
1. can i investigate more, or find a solution myself?
2. i probably need a new system board. Where can i order a new system board?
Recently I purchased a u410 and it has been running great for a few weeks but this morning instead of waking up from hibernation like normal it seems to be stuck in a loop of displaying the lenovo logo then a blank screen with a few seconds on each. This has been running continuously for hours while I try to run down battery in an attempt to reset. I have no bios access during the loop and it will not boot to any usb media. I am now wondering what I should do since it already has data migrated from my old machine and don't exactly want to start over. Is there anything that can be done other than returning it or sending it to lenovo support?
View 4 Replies View RelatedLenovo U410 comes with 24 GB SSD and 500 GB HDD. Lenovo claims that they use some express cache to get faster speed during bootup and opening apps.
Lenovo recommends clean install of ideapad system while upgrading to windows 8.
link:
My problem: As I am doing clean install , I want to delete LENOVO partition. The technical support guy also told me in phone that I can delete the partition and create my own.
But how will I use ssd and hdd? In my laptop, the windows OS was installed in 500 GB hdd and 24 GB ssd was used for some "express cache" .
But if I delete all the partition, how will I configure such that 24 gb ssd is used? Because lenovo does not provide any software named "express cache" in their site.
BUT they provide "Intel Rapid start, Intel rapid storage"
So does these rapid start and storage use 24 GB ssd aand improve my boot time?

All my programs were still there, but images, documents and other files are all gone.
This happens whenever I turn my laptop off and turn it back on, when I put it to sleep and wake it up, my things are still there. I have Windows 8 and I'm fairly new to Windows 8...
I upgraded my brand new U410 to Windows 8, and immediately noticed that shutdown took more than 5 hours, at which point I would just kill it by holding down the power button.

View 1 Replies View RelatedI own a 3.5 years old Acer Aspire 5742G (Core i3 M380; NVIDIA540M). the heat sink or the collinig fan might have some issue as it usually gets overheated when playing games (even CS condition zero/1.6). I don't play games anymore, so its not a problem.
The problem is that I am unable to adjust the screen brightness from the keyboars shortcut (Fn+ Left/Right arrow key), neither from the control panel (Power Settings).
Although I do noticed something that, if I change my brightness settings (nothing happens) and I close the laptop lid (display screen) by folding it down and openeing it back after 3-4 seconds, the brightness is now changed.
Screen automatically dims as I go in little dark areas and gets too bright when it has so much light around it. I am trying Fn+ arrow keys but they make very less difference. Is there any way to control this?
I am using Windows 8.1 and display drivers are Intel HD Graphics Family version 10.18.10.3316.
After updating my Thinkpad T540p, I cannot adjust the brightness in anyway. This is a problem because the screen is too birght and eats up battery.
It appears the only way to adjust the brightness is to use Intel HD Graphics, which isn't so convenient.
Fn keys don't work. changing the brightness on the Power Manager settings doesn't work. There is no brightness option on Windows Power Manager.

Edit: In fact, I think it's posisble that Power Manager to just outright no longer works.
I purchased an external monitor recently so I can extend my Lenovo U410 IdeaPad's display. The monitor connects to my laptop via an HDMI cable. The problem is, nothing from my laptop is displayed on the external monitor.
The external monitor is still left with a black screeen with either the HDMI and Analog symbol flickering back and forth on the top left corner, or a box that shows "Check Signal Cable" with red, green, and blue boxes below.
On Control Panel>Appearance and Personalization>Display>Screen Resolution, I can see that the external monitor is detected: I have the external monitor as Display 2, and I have "Multiple displays:" set at "Extend these displays"I know that the monitor is not broken, because it works as an external monitor for my MAC (via HDMI cable as well) ....
