Keys on my laptop Aspire of F5 FN brightness control - 573 stopped working.

Hello, can someone point me in the right direction to solve the following problem.

I just bought an Acer Aspire F5-573-52MU computer laptop and a week after the purchase (September 2016) my Fn Hotkey no longer works when I try to increase or decrease the brightness (Fn + left or right), but it still works when I adjust the Volume (Fn + up or down).

I also did a full factory reset (as suggested by the ACER Support), but nothing helps?

Needless to say, the screen is very bright and with no control over brightness led to a faster discharge of the battery. If someone had a similar problem on this model, any suggestions to remedy this would be welcome?

It seems that MS Win10 auto update "could possibly have updated the driver ' creating a loss of the functionality of the shortcut key. This would also explain why my factory reset/install failed fix?

Replaced the monitor driver manually in the Device Manager by selecting the generic PnP monitor version. PROBLEM SOLVED, Yah!  Although I think that this problem may happen again on the next update (I hope not)!

Anyway this cured my problem...

  • Aspire Touchpad E 15 Touch (E5 - 511P) stopped working

    Hello!

    I have a 11 month old Aspire E15 Touch (which apparently is officially a "E5 - 511P".) Has the touchpad works very well, but it has suddenly stopped working.

    I restarted the computer, but this has no effect.

    I went to Device Manager and the only mention of "Touchpad" fell under "Human Interface Devices" as a «HID-compliant touchpad»  When I clicked on it says "this device is functioning correctly. I clicked on the driver and then update driver tab, but he told me that the driver I had was the best driver (after a search).

    Then I tried to uninstall the driver, which I did today and the "HID-compliant touchpad" no longer appears. I did a search on the net, but it seems there are different types of touchpad for this model (?).

    A lot of questions:

    -J' have initially ruled out hardware failure because the computer says that the "HID-compliant touchpad" worked. I made the mistake to believe this?

    -How can I tell what type of Touchpad has my machine?

    -If I find the correct brand of the Touchpad, where should I save the driver (if I can download it)?

    PS 8.1 64-bit Windows.

    Thank you

  • Plan to install Win'a again. & operating system on the hard drive clean. We hope to upgrade memory of the laptop later, having heard it's op system stop working.

    Supposedly the installation process corrects the operating system on the computer's particular configuration and any changes cancel the operating system to function.  Dosen't seem very friendly for computer tinkering.  Having read both 1) that only the motherboard is recognized and fixed 2) or that all the components of the laptop are fixed on and nothing can be changed.  Anyone know if any of them are true? Thanxs, Steve

    (Vivid RAM) memory or not should not make the installed Windows 7 from functioning.  If you change to another laptop and Windows 7 is OEM, then yes the Windows 7 will not work correctly.

    I was stupid enough to scan with REGSERVO and since then very few things come without a fault, most common is

    C:Windows\system32\config\systemprofile\desktop... is not available or has been moved. System Restore does not work,

    When I look at the properties of the system it is all grey fault 0 x 81000203 views. Desperate ChapChappie

    Thanks IronFly,

    You fixed the restoration of the system for me and is currently working.

    The problem with the desktop really only apply to the missing icons, they were more a symtom of the fault on all the software that I tried to run. It came after I scanned with 'Regservo' that I would NEVER use again and advise others NEVER use.

    I couldn't remember go with a system of failure so I had to resort to pay a technician to fix my problem, seems fine now!

    Thank you very much once again you get a Kudos from me

  • On my brilliance of PC hp pavilion dm4 laptop controls do not work for a week.

    Product name: HP pavilion dm4

    Product number: LW475UA #ABA

    Operating system: Windows7 64-bit Home Premium

    For about a week, I'm not able to change the brightness on my laptop. Before I used to decrease f2 and f3 to increase the brightness of the screen. I do not know what is is past these commands stopped working, but (f10, f11) volume controls are still working fine now too.

    I contacted the support center hp on this issue they updated the graphics driver and they have updated the bios also but the problem is not resolved.

    When I click on the controls of light I can see the brightness meter icon but it wont increase or decrease when I press f3 or f2, respectively and the brightness meter shows brightness is at the lowest level that it is at the highest level.

    Thanks in advance for your help

    Hey I found the solution for my problem. On my laptop brightness controls do not work because I installed logmein (remote desktop) application that also installs some graphics drivers if you want that the features of the rotation of the screen on my laptop when I access my laptop to remote location. It seems that this driver causing the problem, when I completely uninstalled the app logmein brightness keys still work. For you all similar applications like this can be the cause of the problem. To solve this, go to the device (device type in the start menu Manager) see Manager is related to the applications that you have installed all the drivers are there under the display adapters in the Device Manager window, in the affirmative, uninstall applications completely it may solve your problem too.
