LCD Brightness Control Doesn't Work After Resume From Sleep / Hibernation
Jun 12, 2011
Occasionally, when resume from hibernation/suspend, display brightness control doesn't work. Means that Fn + F2,F3 doesn't work, change from Windows Power Options doesn't work, change from intel graphic doesn't work. If I have to restart some services to get it working? It's occasional and I can't find anything exact in EventLog. My system is HP Probook 4230s with Core i5-2410 with intel HD3000. Latest patches on both Win 7 Pro 32-bit and intel driver. Restart machines solve the problem, re-hibernate or re-suspend machine occasionally solve the problem, but mostly not.
This has been going on for ages. Upon a fresh boot, keyboard brightness dimming does not work until I put laptop to sleep. Then, the FN+up/down works fine. I can't remember if this has always been the case, but I know when I first got my laptop, Windows 7 pre-installed, the auto-dimmer was working. Now I am not sure it is (not that I mind, I don't want it on). Now, when I check Advanced Power Options, the "enable auto dimmer" isn't even listed.
I pretty much need to have quick brightness keyboard control due to my light sensitivity. Win+X is annoying to resort to.
Also, when the FN+up/down keys DO work to change the brightness, it says: "Ambient Light Sensor Disabled". (Also also, I checked, and I have no "sensors" installed, so says my system.) Also, my keyboard has a FN+Auto Dimmer key that is the 'left' key in the arrow set, but it doesn't appear to do anything. Or am I completely missing that THIS might be what I need to hit in order to enable keyboard dimming commands? (I haven't tried, but right now, after coming out of Sleep mode, the dimming commands are working and the "auto" option does nothing).
Anyway....

Don't know what else you need to know. I did some searching online and this might be a BIOS setting, but I didn't want to go that route before I talk to someone. (PS, Power Options, as far as I can tell, only lets me manually, on the screen, adjust brightness - it seems to have no control over keyboard adjustment settings).
my hp remote not work on windows 7. After 2 years i preinstall from vista home preimum to Windows 7 ultimate. My laptop is hp pavilion dv7-1023cl and i have all windows 7 x64 drivers, and all hp services running on automatic mode, HID also. I try many many times to set up IR to receive signal from remote, but i no have success. This is information from back side on remote:

I have a problem with hibernate/sleep in windows 7.when i set pc to hibernate or sleep, the power turn off, but it does not resume. I press any key on keyboard, power does not come back on, then i push power button, power on and display not windows unexpected shutdown screen, choose safe mode or start windows normally, no blue screen or crash dump. I tried all kinds of settings. still same.
I've recently encountered a problem on trying to take my laptop out of Hibernate mode. The machine hibernates normally, but when attempting to resume it will display a black screen with a flashing cursor in the top right-hand corner, then get stuck there. At the moment this is more an irritation than a serious issue as manually turning the machine off and on again at the power button offers me the choice between trying again and deleting the hibernation file's data and rebooting as normal. If I choose the first option the computer will lock in the same place as before; the second option has it booting as normal.
I've tried troubleshooting the problem myself but my limited understanding of how my laptop actually functions means there's only so far I can go by myself. Is there any way I can go about fixing this or will I need to get someone to take a look at it? ETA: I just tried waking the computer from Sleep only to find that it had a similar problem there as well. No flashing cursor, but the screen just went black and the machine wouldn't respond until I turned it off and back on.
My remote control (Windows 7 Vista XP Media Center MCE PC Remote Control and Infrared Receiver for Home, Premium and Ultimate Edition) doesn't work with Netflix online streaming. The pause button works fine with live tv, recorded tv, and DVD playback but not Netflix.getting the pause button to work with Netflix?
I'm running Windows 7 Home Premium SP 1 64-bit on a HP 620 (just a year old).
Lately, whenever I return to the laptop having left it alone for some time (Power Management set to 'Sleep' after 10 mins), and try to resume, I can hear the it resuming (fans etc.), however, the screen remains completely black.
The only solution is to shut down the system manually and boot it up again.
nvidia control panel shows 2nd monitor as vga but is dvi and doesnt work it recognizes otherwise as fine in the windows settings and nvidia control panel it got reset ? after I woke it up from sleep how do i force it back?
I've bough a Dell Inspiron 1564 with Windows 7 home premium x64 last month and everything was fine until a few days ago, when sleep mode stopped working. When I close my lid and open it up after some time there are 2 things that might happen:
1. The screen is just black, all the buttons are lit, I hear the fan, but no reaction at all. So I just forcibly turn off and turn it on again.
2. After opening the lid, nothing happens, when I try to turn it on, it loads up, but informs me that windows has not shut down properly last time (or something like that).
as described I use a Logitech G510 keyboard with multimedia keys and the posibility to insert a headset into it (the keyboard got its own soundcard). The keyboard also got a volume wheel which worked with Vista like it should: I could controle the speaker's volume by the keyboard.
Now with Win 7 I can't use the wheel anymore, even with the latest drivers.

I'm using the Lenovo multi touch driver for my X61T. With Windows 7 build 7000 the same driver when I wake my laptop from sleep the touch screen works. Starting with build 704x (i can't remember the exact build but it was the first leaked x64 build) when I wake the machine from sleep the touch screen doesn't work (both pen and finger touch)
I have tried to change USB settings but I haven't seen any fix. A restart of the machine means the tablet works again. Any ideas about a patch until Lenovo makes new drivers for Windows 7?
On a brand new, freshly installed Windows 7 Ultimate 64. I get the following error when resuming from Hibernate: "Your computer can't come out of hibernation. Status 0xc000009a". No other info, no reference to any file such as hyberfil.sys. I have tried to "powercfg -h on/off", reboot defrag and reactivate hibernation, however the problem is still there.....what can I try?
I had a problem about ipv6 on windows 7 for a long time. I have a ipv6 & ipv4 dual stack network. Every time I wake up my computer, the ipv6 cannot work. The appearance is that I can't ping and access ipv6 website. But after some research, I realize that only the DNS part is broken. When I ping the ipv6 site like ipv6.google.com, it tells me it find no host, but if I use nslookup, I can find the ipv6 address. And the following are my tries:
ping ipv6.google.com -- not work ping 2a00:1450:8001::68 -- does work, the ip is the ipv6.google.com address ping -6 ipv6.google.com -- does work like the above
I currently run Windows 7 ultimate 64bit, 8gig ram, intel i7-2600k cpu, and my OS runs on an OCZ SSD (all specs are in my profile)Sleep mode is set to S3 in BIOS, I have hibernation disabled (so no hibernation.sys file on my c drive)When I put my computer to sleep then immediately wake it up, the login screen shows instantly, I type in my pass and it loads in like 0.5 seconds.When I put my computer to sleep but wait for around 1-2 hrs before waking it, it shows the login screen instantly but after i hit login, it gives me the Welcome spinning circle thingy for like 20 seconds before I can see my desktop. That's like longer than my entire boot-up time excluding POST.Event viewer doesnt show any performance delay, and I dont think my OS drive (OCZ vertex 2) has a cache so I have it disabled. I'm sure all my mobo drivers and graphic drivers are up to date.
I use Pangobright because the brightness of my Toshiba laptop doesn't go as low as I want it to be, when I'm using the laptop in complete darkness. But Pangobright also doesn't seem to go as low as possible, and when I dim it too low, I can't see a part of the screen unless I'm looking down at the screen. Is there a better screen dimming software?
So brightness works well when i turn on the cmoputer from shut down.I can change it, use mobility center to change it, use power options to change it, use FN + Fx keys to change it.Then i go to sleep mode as i travel around (laptop) and when i turn it back on, the brightness is much dimmed (about 60%) and i cannot change it.In fact, the brightness box in Mobility Center has disappeared..ower options, whenever i use the brightness slider, no effect...N + Fx keys do not work, also.The solution is to either enter hibernation mode, and turn it back on or to Shut Down, then turn it back on.
Is there a group policy to lock down the brightness settings that are normally configured into the control panel power options? Or alternatly, can I force these back to particular settings by saving and restoring regsitry keys upon user login?
i am including the minidump from the latest crash to see if i can get some help with this one, it is driving me nuts. i put the pc to sleep at night and then when resumed in the morning i am either greeted with a smooth working desktop or a bsod. i am at my wits end trying to sort this out, so i will come and ask the experts.
Win 7 home premium,4 GB RamApparently the computer resumes from sleep but really it freezes and no input from the keys or mouse are valid---at this point only option is to reboot.
I have a Lenovo ThinkPad T400 running a fresh install of Win7 Pro x64 with SP1. I did the clean install as normal, getting necessary drivers from Lenovo and leaving the rest to Windows. In the past this has worked well.
This time I am having an issue where resuming from sleep or hibernate takes longer than starting the system from shutdown. Looking at the event logs it seems to be driver related. I open the lid, press the power button, and I get nothing other than a power light, no HDD access light as usual. This usually takes quite a while. Once I get to the logon screen, it is unresponsive to both password and fingerprint reader. It sits like that for a while and than after logging on everything works fine.
The machine has ran Norton Internet Security 2012 from day 1 and I have no reason to believe that this is malware related.
I have saved the "Diagnostics-Performance" section of event viewer an EVTX file which should be attached to this post. It will open in event viewer.
EDIT: It says I am not permitted to upload this kind of file? I have uploaded it to MS SkyDrive instead. [URL]
Every time I put my computer to sleep or hibernate and wake it up, the computer resumes to a screen stating "Windows failed to shut down correctly" A recent hardware or software change might be the cause and I'm asked to choose how to restart.Quite similar to the screen I would get after a crash.
My laptop (Dell Vostro V13) is stuck in some kind of limbo. It went into sleep mode and won't wake up fully! It "resumes" the boot-up sequence right up until the four windows colors do their characteristic swirl animation - then the screen goes black.I can't seem to force a fresh restart b/c every time I power off and back on, the laptop tries to *resume* and gets stuck again.Hitting F2 and F12 allows me to run bios and memory tests, but to no avail. The laptop always attempts a resume.How do I break this sleep-resume cycle and do a fresh restart? Reinstalling the OS is out of the question (too many important files will be erased
Although I found some issues that are almost similar, nothing seems to really solves the issue I have.
Build 7068, x64 freezes after a resume from sleep (S3). The desktop image is visible but the system totally hangs. Only a hard power down works.
I use two USB devices (keyboard and remote) and both can resume the system from sleep. Strangly the system did work for the first day and now even a clean install fails on resume...?
Vista x86, had no issues at all, rock solid operation for almost a year.
System config:
Gigabyte EP45ds4 (BIOS P9), E8400, ATI HD2600pro (this card only works with driver 8.12 in Vista SP2 compatibility mode to enable svideo output), HVR2200.
I have a weird issue with my wireless adapters. I will put my computer to sleep and then resume my work a few hours later, when the computer wakes up both wireless adapters are disabled and I have to go into adapter settings to re-enable them. My adapters are a netgear wna1100 usb adapter and an azio pci card adapter.
Having problems with my Windows 7 PC which is periodically slow to resume from sleep.System Specs is up to date, note op system is on 128GB Sandisk SSD.
I am having some issues with Windows and resuming from sleep. I have an overclock of 4.2 GHz and everything works great, but after I resume windows from sleep, the clock drops to normal Turbo Boost Ratios ranging from 3.4 to 3.8. Naturally after a restart the clock goes back to 4.2 as if nothing ever happened.
Note: I have tried Disabling various power functions in the BIOS such as EIST, C1E, etc.
I am using windows 7 ultimate and facing great problem. Whenever I put my PC to sleep, on resuming it crashes giving a blue screen of death message. I am never able to put my PC on sleep which quite inconvenient. Actually my video card does not support windows 7 aero or there are no WDDM drivers available for my card which is ATI RADEON 9250. I am ready to upload any crash minidump files or any other log files. Also tell me if any WDDM drivers are there for my video card as I am not able to get them anywhere. Is this video card the only reason for the problem
Have a Windows 7 PC working fine for 6 months, now fails to resume from sleep every time. On attempting to resume the PC appears to go through a powering up loop (Hard disk and fan spin up) which then goes off and repeats indefinitely till you force the power off by holding town power button.When changing 'allow hybrid sleep' in Power Settings to disable; it cured it for a few days. The issue came back, so tried enabling this setting - same result. Disabled again, same result.Update Intel Graphics Drivers to latest. Fixed the issue again, just for a few days.
I'm having a problem where if my laptop is idle and the screen goes black, I can't get it to resume. I try moving the mouse and hitting buttons, but nothing happens. I have to completely shut the PC off and start it again. Also, if I put it to sleep, the same thing happens (it goes black but doesn't sleep or resume). My drivers are all up to date but it still happens.
