Windows 8.1 Toshiba Satellite - Unable To Adjust Screen Brightness

Aug 24, 2014

I have a Windows 8.1 Toshiba Satellite L875D-S7332, with a AMD A6-4400M APU processor with integrated graphics. My display adapter, according to device manager, is a AMD Radeon HD 7520G.

Now, my problem is that I'm unable to adjust the screen brightness of my laptop. I haven't made any recent changes, and I noticed this about a week or so ago(I don't typically change my laptop brightness, so this could have been happening for longer). In the mean time, I've tried rolling back my display drivers, with no success, and also updating to the latest driver set, which has also not worked?

HP Recline 23 / Windows 8.1 - Cannot Adjust Screen Brightness

Jan 25, 2014

I have a new computer , HP recline 23 . OS is Windows 8.1 . It came out of the box with Windows 8 , so I had MS store update to 8.1. The screen is set very bright , OK for day use but too bright for night use .

My problem is that I can't adjust the screen brightness. After clicking on the charms menu and clicking on settings , the brightness icon is greyed out . It says windows cannot adjust brightness on this computer. I tried the various locations where the brightness slider may be but all the relevant screens show no brightness slider.

I don't know whether win 8 had the brightness control before upgrading to 8.1 ( I mention this because several people complain that after upgrading to 8.1 , they loss brightness control amd regained it by rolling back the driver )

I tried the update driver option but it says my driver is already updated. The roll back option is greyed out ...

BTW the display adapter shows two adapters : Intel 4600 and Gforce GT730 . How do I check which one is being used?

Hardware Drivers :: Windows 8.1 - Brightness Won't Adjust?

Oct 19, 2013

since I updated to Windows 8.1. My screen is stuck on dim. It's not dim enough to be unusable, but it's dim enough that I wish I could turn the brightness up. If I use the hardkeys on my keyboard to turn it up or down, the bar will go up and down, but the brightness won't change. Same goes for using the settings charm brightness bar and adjusting via control panel. I've tried updating my display and video drivers, and messing around with the battery "power plan" settings, but after all that it still won't change.

Graphic Cards :: Brightness Won't Adjust In Any Way When Its On?

Nov 11, 2013

I've noticed that whenever I unplug my charger my brightness dims down to a point where I know its on, but I can't use it. Usually I have to put my computer to sleep and turn it back on to get it to fix. Also, the brightness wont adjust in anyway when its on. I've tried the function keys and the setting in the side bar. I have a toshiba laptop running windows 8.1 . I also have recently completely wiped it thinking it was a virus of some sorta with no change.

Hardware Drivers :: Screen Seems Dim - Brightness Won't Adjust

Jun 7, 2014

Well I've had my laptop for almost 5 months now, however I did break it and got a screen replacement yesterday. Ever since then my screen seems dim. I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem. I had no trouble altering my brightness before my screen replacement so I do presume that the screen that the shop fitted wasn't the correct one and therefore a cheap option.

Hardware Drivers :: Laptop Screen Brightness Won't Adjust

Oct 18, 2013

I went and bought a new laptop since my old one was starting to die on me and stuff. It's a Samsung ATIV Book 4, and it's really nice. This is the first hick up I've had with it so far, and I noticed it happening today. I noticed my screen was really dim today as I was using it, so naturally, I use the Fn key to turn it up, but nothing happens. Up in the top left of the screen, it shows a little brightness meter going up and down as I turn it up and down, but nothing changes. I went to the power options menu and tried to adjust it there, and alas, nothing happened. I even tried disabling the display driver and restarting it, but that didn't do anything.

Upgrading To Windows 8 On Acer Aspire 6935

Apr 11, 2014

I am currently typing on a Acer Aspire 6935. It originally came with Windows Vista Home Premium and then I bought a copy of Windows 7 Ultimate. It took me a while and when I say a while, I mean about 10 weeks to find ALL of my correct drivers and this laptop is special because it has some fantastic speakers. So finding the right driver for the speakers was a pain in the... Without the drivers, my sound horrible. I want to upgrade to Windows 8 because I like the new interface and I like Windows 8.1 Update 1, however, my drivers are a problem. I found the correct drivers but I forgot where I downloaded it from. What can I do? If I upgrade to Windows 8, will it keep my drivers?

Windows 8 - Recovery From HD Failure On Acer Aspire M5-581T

Jun 30, 2014

My system started pausing/freezing, log files showing some errors about not finding some *.dll files. The system will still boot; I enabled the administrator account, but have lost the original user profile. All the docs/files are still there in the usual c:usersusername... directories. Installed Seagate's SEATOOLS app and it reported a failure, not completing the process. I used the recovery app from Acer and created a bootable recovery device (Seagate expansion portable drive) and a CD of drivers and apps. I am told this system has a small SSD, but it is hidden because it is for the OS, Windows 8.

I've put an identical replacement drive in; I changed bios to boot from the external USB device and it comes up in what appears to be recovery mode. I select option to completely refresh system, but it then comes up with "drive where windows is installed is locked". I select the reset option, it asks whether I want to re-partition. If I select yes, it returns 'unable to reset pc system drive cannot be found'. If I select no to repartition, it returns 'unable to reset. A required drive partition is missing.'

Using the recovery app, I can get to command prompt; it comes up as windows ver 6.2.9200, x:windowssystem32, The c: dir<enter> command returns efi (D), bootmgr, boot (D), bootmgr.efs and sources (D). I insert another usb stick and those files show up correctly.

Also, a byproduct of installing drive it indicates it can't find a battery now!

Why the reset or recovery options are not able to see the replacement drive? Since I used a Seagate expansion portable drive rather than a 16gb USB drive, is that the problem? I believe Windows 8 won't allow the use of a DVD for the recovery process (size issue?).

Could I consider doing a reformat and clean install of Win7 pro? Will I need to change the boot bios setting from UEFI to legacy? Would I still be able to reinstall Windows 8 at some point in the future if necessary, or should I try to work with the Windows 8 configuration?

Setup Installation :: Acer Aspire M7710 - No OS After Windows 8 Reset

Jun 29, 2013

I have an Acer Aspire M7710 which I installed Windows 8 on.

I wanted to use the reset windows option under the advanced settings option. After selecting the reset option it said it would reboot. This was about 5 hours ago and all I have had is a black screen.

Eventually I powered off my computer after 4 hours waiting as something seemed wrong. When I powered my PC back on I get nothing, just a black screen again.

I thought I would just boot from the Windows 8 dvd and reinstall but for some reason I can't boot from dvd anymore.

I googled around looking for option how I could enter my bios or change the boot order for cd/dvd but I can't get any keyboard shortcuts to let me boot from dvd or enter the bios.

How I can boot from dvd and reinstall?

Acer Aspire E1 570 Battery Dies At 40%

Sep 15, 2014

I have a Acer Aspire E1 570 laptop that I use for college, the laptop is less then 8 months old. For some reason recently it starting going dead at 40% battery charge remaining. I ran a powercfg -energy from the command prompt and it said that my batterys designed charge is 37000 and last full charge untill the battery read it was fully charged is 36526. I use the laptop on the battery all the time while i'm at school. I was thinking maybe just refresh the PC from the recovery i made using the provided software with the computer. I'm unsure if that would correct the issue.

Setup Installation :: Dual Boot Acer Aspire V5 With Windows 8.1 Pre-installed

Apr 14, 2014

I am using Windows 8.1. I have an Acer Aspire V5-571P computer with Windows 8.1 pre-installed. I want to install my licensed copy of Windows 7 Professional on it as a dual boot to dual boot Windows 7 and Windows 8.1. I have seen that it can be done, but I cannot figure out how to correctly do it. I have already had to re-install Windows 8.1 once from a USB Recovery drive which was not fun. So how to do it and get it done. I love windows 7 Pro but I can't figure out how to do it.

I have already turned off secure boot in bios. However, UEFI mode is still active vs legacy bios which is the other mode I have.

ACER Aspire V3-571G Restarts Suddenly?

Apr 8, 2013

I have an Acer Aspire V3-571G-53216G50Makk.

As some program I use usually are not 100% compatible with Windows 8, I tried to format and put windows 7.

When I installed windows 7, the computer started to heat up and shut down too .. I was convinced that the problem was the BIOS. So I updated it from v2.04 to version 2.13.

I did not notice any difference and the computer continues to shut down. I had only to open a game for 30min.

I went back to change the BIOS to UEFI type and installed again windows 8.

With windows 8 computer already accelerates the fan and he does not turn off so many times.

As the UEFI BIOS type is recommended for windows 8, that have logic ...

However I still find that the computer does not work well. If I play something for 1hour, some times the computer shuts off and sometimes not.

The computer shuts down and after 2-3 seconds, it automatically turns on.

I think this is very strange ...

The fan speeds up a little, but she never arrives at full speed!

So I thought it was a problem in the version of BIOS and I have tried all the ways to replace the original version, v2.04.

Unfortunately, without success!

I no longer know what to do ...

Actual BIOS version - 2.13:
h**p:// tep1=Notebook,%20Ultrabook&Step2=Aspire&Step3=Aspi re%20V3-571G&OS=8cn1&LC=pt&BC=Acer&SC=EMEA_21

Original BIOS version - 2.04:
h**p:// tep1=Notebook,%20Ultrabook&Step2=Aspire&Step3=Aspi re%20V3-571G&OS=8cn1&LC=pt&BC=Acer&SC=EMEA_21

Setup Installation :: Acer Aspire V5 - No Operating System Found After Windows 8.1 Upgrade

Aug 11, 2014

Acer Aspire V5 laptop that was running an OEM Windows 8 to upgrade to 8.1.

After selecting the Upgrade to Windows 8.1 via the store, the system went through it's install procedure, however after it does an auto reboot, it gives you a blank screen with the message No Operating System found, in the upper left corner.

But, you can turn the machine off and back on, and it will boot just fine. However if you select restart it does the same thing "no operating system found", on restart and again you must power down and power back on.

I have searched for fixes, but all seem to point to some sort of re-install process. I am not to crazy about the idea of re-installing to factory settings or doing a repair back to Windows 8 and attempting to upgrade again, are their any known shorter fixes for this?

And if I do go back to Windows 8, and try to upgrade again, what is to say it won't happen again?

Debugging :: Random BSOD When Gaming Acer Aspire

Sep 15, 2014

I've just bought a new Acer Aspire V3 772G. My laptop crashes or reboot by itself every times i play a video game. Sometimes 5 minutes or 2 hours later.

-I update all the drivers from the Acer Website.
-I've updated the Bios to 1.15 (the latest).
-I've already run a memory test with Memtest86 during 10 hours : no single error.
-I've run a CPU test with intel with intel Processor diagnostic. There's a warning which says
CPU Frequency Test Passed with Warning!!!

The processor frequency could be affected by power management features. In order to ensure the processor frequency is not affected by a power management setting, enter BIOS, load defaults, and disable any 'Over-Clocking' or power management features that may affect processor frequency. Also, set any software applications which control power management features to default.

I didn't overclocked my CPU. I don't know whether it's overclocked or not. It's a second hand laptop.

-I've tried to test my graphic card with AtiTool but when i run it it says ''The Kernel Mode driver does not seem to be running A device driver is required for communication with your video hardware.
-I've also run a hard disk test with HDtune and it seems that i have 381Mb as bad sector.
