Apple :: Friggin Electric Sound When Adjust Your Screen's Brightness

Mar 30, 2009

it's that friggin electric sound when you adjust your screen's brightness. Not that the sound is loud or anything but it's so annoying. Even clean install of mac os didn't help.

And it's not the hard drive that's making the noise. It seems to be coming from top left corner. Blackbook is half a year old and it started to emit that friggin noise a month ago. So did anyone had the same or having the same problem and did anyone removed this god dammed irritating sound !

Dell XPS 15 :: Can't Adjust Screen Brightness Using Either Function Key Or In Control Panel

Dec 4, 2013

I can't adjust screen brightness using either function key or in control panel.  Using the function key the little panel of brightness volume shows up on the screen but does nothing.  And in control panel, through either the bottom brightness scroll or the power option won't change anything. Only time when the brightness will change is I unplug the power, but in the power settings it won't let me change/adjust the brightness.

And what is the battery function key for? I press it and it does nothing.  XPS L521x

Lenovo P400 P/Y/Z Series :: Touch Screen Brightness Won't Adjust

Apr 13, 2013

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.

Acer Aspire V5-431P-4653 :: Cannot Adjust Screen Brightness Running Windows 8.1

Feb 27, 2015

I am having an issue with my Acer Aspire V5-431P-4653 running Windows 8.1, namely, I cannot adjust the screen brightness at all. It seems to arbitrarily select a brightness level upon start up and from that point I cannot change it via the Fn and directional keys or through the control panel power settings. I have owned the laptop for a year and a half and this problem began roughly a week ago. 
 
Of note, when I attempt to use the Fn and directional keys the brightness icon that pops up stays at the frozen brightness level - it does not move at all. In contrast, when I open the power settings and attempte to change the brightness from there, the brightness slider will move wherever I drag it, but the screen's brightness itself does not change. At startup the screen's brightness may be at full, minimum or somewhere in between - but regardless it will not adjust.

Lenovo T400 / T500 :: No On Screen Display Of Caps Lock / Volume / Screen Brightness

May 27, 2014

I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.

HP Envy 15 Display :: Touch Screen Clicks On Wrong Display

Jun 15, 2014

Today, I tried connecting an external display to my HP ENVY TouchSmart 15 laptop, via a USB hub, only to discover that using the touch screen points at the corresponding part of the external display rather than the inbuilt one (the displays are being extended). Can this be changed?
 
I'm using the same 64-bit Windows 8 installation and drivers that the computer came with.
