Satellite C855-1CH - cannot control brightness after closing / opening lid

hello
i have a problem with windows 7 64 and amd 7610m driver, when i install the driver from toshiba site, have problem with hibernate,
When i closed lid and unplugged ac adapter and after few minutes/hours i turn on the computer the brightness is same (my brightness with battery is 30% and ac 100%) and can't change with function keys, and power option dont have brightness monitor, but only i reboot the system its back ,
How fix this problem?
I trying to install driver of amd 7600/7500 and the battery time elapsed fast with down brightness in 1.5/2 hours (with 7610m 2.5/3) and the fan of motherboard work strong , while i only use in solitaire.
thanks for help!
if someone can to help me , contact to me.

>i try to install driver from amd site -driver amd 7500/7600 not amd 7610m . this work without problem but the fan work very strong and Heats up faster i afraid Afraid it will not destroy my computer beacuse is diffrent driver.
So it seems the problem is related to the display driver because as you mentioned, using the display driver from AMD website the brightness control works without problems.
The C855-1CH series was equipped with the graphic chip which is used in other notebook models as well.
Therefore the GPU driver released for other series with the same graphic card chip should be compatible.
I recommend you to test other graphic driver versions released for the following models:
Satellite C850 PSKCCE, PSCBYE
Satellite C855 PSKCCE, PSKCEE,
Satellite C870 PSC8EE, PSCBCE
Satellite C875 PSC8EE, PSCBCE
Satellite Pro C850 PSKCDE, PSCBZE
Satellite Pro C870 PSC8FE, PSCBDE

Cannot Control Brightness After GNOME 2.30

I upgraded to GNOME 2.30 yesterday, and before installation it asked if I would like to switch my power settings from devicekit to upower. If I am not mistaken, upower is newer and supposedly better. In any case, I am now unable to control the brightness on my laptop. Before I could only control it through GNOME's power settings. However the bar that dims the screen is now gone.
Is there any way to go back to devicekit? I tried downgrading, but it wouldnt let me.

Excellent news! I've just updated the system with pacman -Syu and the brightness control work again!
But i still have the problem with the notifications when i raise the brightness to its max.

Equium A60-692 won't restart after closing the lid

Most annoying, the only thing I can do is hold the power button to switch off &switch back on again. Is there some combination of keys i should be pressing to bring her back form the brink after closing the lid, or is this a fault?
Thanks

Usually when the memory size changes, the system can recover.
Remove the battery and AC Adapter, then remove one of the Memory Modules, and power up.

Satellite P200 makes some strange noises after closing the music

I've got a Satellite P200 and the flash cards don't react and when Ive played some music.
The computer makes some strange noises after closing the music?
Help me please!
grtz Wendy

Hello Wendy
Please don't understand me wrong but it is not easy to understand issue described in your posting.
I have the same notebook model and everything works well. I hear music daily on Windows media player (mp3s) or listening online radio using Winamp player.
At the same time I can use flash cards.
What to say about strange noises? Who knows what do you mean exactly and how should we understand this?
Please be so nice and explain us exactly what do you do and what kind of noises you can hear.

Source Safe causing LabVIEW Quick Start Screen to not appear after closing open vi windows?

Hey All,
We've recently implemented Source Safe version control for LabVIEW on XP and I've noticed that LabVIEW is hanging between closing open vi windows and showing the Quick Start Screen. The usual pattern is for the Quick Start window to appear after the last open vi window is closed. Instead the vi window is closed, the tab at the bottom of the screen says debug development and the Quick Start Screen does not appear, the tab does not read "Getting Started."
I think it is a LabVIEW <--> Source Safe issue when I do a Task Manager Exit on the LabVIEW process that I sometimes see a dialog box asking if I want to save changes in memory to disc and those files are not checked out. But it is too late at that point to do anything as XP clobbers the application before I can do anything.
Anyone else have this issue?

What LabVIEW version do you use?
I have used SourceSafe in every version from 8.0, and in the way some bugs are resolved.

Wireless mouse and Keyboard Issue after closing the lid - external display

Can anyone give any insight. Recent purchase of a new Late 2008 15" MBP. I have connected it to an external 24" Apple monitor on my desk and use a wireless mouse and wireless keyboard on my desk top. I have configured the laptop to wake on bluetooth devices. So here is the problem: The laptop when the lid is up recognizes the bluetooth keyboard and mouse. I close the lid/screen. Laptop powers down... the after several seconds I move the mouse and the laptop comes alive... But after that there are no bluetooth devices attached. When I use the mouse, I get "connection lost" with a white figure of the mighty mouse on the screen. The wireless keyboard is not there and I have to open the lid and manually find the mouse and reconnect. The keyboard seems to work however....
Apple..... any thoughts..... anyone?????

Hi Stentdoc; I'm thinking, 'connection lost ~= sorta low AA batteries in the Mighty Mouse? (I would put in fresh AA batteries in the mouse and keyboard, to eliminate as an issue that the 'connection lost' is due to low batt voltage; that this is causing the failure to wake.) ... then, in System Preferences > Hardware > Energy Saver, settings for Power Adapter > Sleep, set to "never" for "Put the computer to sleep when it is inactive for ..." to eliminate that as a conflict when trying to wake with bluetooth from sleep induced by closing the lid ...
Check your current "Sleep" setup (I left my MBP as "3")
go to Utilities > Terminal
After you launch Terminal, the first step is to determine which sleep mode your Mac is currently using. You can both view and change the sleep mode using the Unix program pmset. To see your current settings, type (or, copy and paste)
pmset -g | grep hibernatemode
press 'enter'
You should see something like this:
$ pmset -g | grep hibernatemode
hibernatemode 3
So your machine is using mode 3 ... thanks to the documentation for the handy Deep Sleep Dashboard widget, which puts your machine immediately into hibernation mode (so you don’t have to yank all the power sources to invoke it):
* 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
* 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
* 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
also, I enabled this (to change back, input "lidwake 1":
go to Utilities > Terminal
type in sudo pmset lidwake 0 then "enter"
it will ask for your password. type it in, that's it!
Now, when your computer is sleeping with the lid closed, when you open the lid nothing happens until you press any key ... nice: keeps it off when accidentally opened, like in a backpack?

Kernel 2.6.32.2-2 black screen after closing laptop lid (intel + KMS)

Today I updated my laptop with the new 2.6.32.2-2 kernel from core. Previous update of my system was just a few days back, so there are no massive changes to other packages and I also don't use testing packages.
Since the update, after closing the laptop lid (which just blanks my screen) and I want to continue working I just have a black screen (no backlight) and the screen won't respond to mouse or keyboard input. I have to reboot (ctr-alt-del or pushing my power button) or switch to VT1 and back to VT7 to get my screen back. I'm absolutely positive that this was not a problem before, it worked fine with 2.6.30 and 2.6.31 kernels with my same configuration.
HP 6730b laptop
Intel GMA 4500 (Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07))
Intel driver 2.9.1-1 using KMS with early start (modprobe.conf) and I rebuilt my initcpio to the new 2.6.32.2-2 kernel
Gnome 2.28.2
Can anyone confirm this behaviour? Should I file a bug somewhere? I read about lots of upgrade problems with this new kernel, but for the rest everything else works fine so far.
Thanks for your feedback.

Isn't suspending and resuming a session exactly what you're doing (or hoping to do) when you close your lid and then open it up again? I.e., putting the machine into a low-power sleep state and then having everything come back to where you were when you wake it up? You mentioned that the Gnome power management tools depend on pm-utils, which suggests that somewhere in there "pm-suspend" is getting called. If you can find out where it's getting called (i.e., in some script that Gnome power manager uses), and try changing it to "pm-suspend --quirk-vbestate-restore" (or one of the other quirks, perhaps), then that may bring your screen back on wakeup.
Hehe, nope I don't hope to suspend :-) I just close the lid to save the display (and some power) but want my machine to keep running (when downloading torrents or when I'm going to eat etc...) Also it keeps the dust from entering the keyboard ;-)
I also took a look at the post where there should be a patch present, but I think it's for another problem: flickering screens.
For me it's a bug in intel driver or kernel, but still it's strange that KDE doesn't suffer from this!

I don't think my MBP slept after closing the lid - it was hot when I woke up

I just came back from an overseas trip and hooked my late 2013 13" MBP retina back up to the LG external monitor. When I went to bed I closed the lid. What I expected to happen was for it to stay awake for a certain number of minutes. Then the external monitor display would go black indicating it was asleep. But because an external monitor is connected it would wake up as needed for Carbon Copy Cloner at 3:30 am. But then go back to sleep.
However my MBP seemed too warm when I just came downstairs. The body and lit were noticeably warm.
Shouldn't it eventually sleep and not be fully awake in clamshell mode in this situation?
Thanks,
Doug

And another Apple Care chat session. But I still can't figure out exactly what's going on, and we seem to be going in circles.
Hello, Doug! How are you doing today?
OK. And you?
I’m doing really well, thanks for asking! How can I help you today?
Well, I tried talking about this via chat support earlier, but was getting wrong information, so I thought I would try again and take a different approach to how I ask .
I’m currently reading through the chat transcript to get a strong understanding of what you were going through.
If you read over the chat you can see we digressed into a separate question about whether the "turn hard drive when possible" mattered to the internal SSD and he said it did and pointed me to a support page which said it did NOT and then he said, "there you have it! have all your questions been answered" but none were so I gave up.
Anyway...
Basically it's just this. My MBP is connected to an external display. In the energy settings I have my MBP set to not sleep when the display sleeps so I don't lose some Terminal SSH connections when I'm working.
But when I'm going to sleep I thought I would let it power nap and cool down.
But I've noticed the MBP is warm in the morning. Also I noticed that open SSH sessions were not broken. So I think my MBP is not going to sleep.
Perhaps the computer thinks it’s going into Clamshell mode since it’s connected to an external display via HDMI, correct?
I did read in help that if you hold the power button down 1.5 seconds an option dialog will appear and from there I can select sleep. I did that, but this morning it is still warm and the connections were not broken.
Let me look into this, I want to do everything I can to make sure you’re getting your questions answered this time.
Yes, I believe you are correct. That it is just going into clamshell mode, and even though I manually selected sleep from the power button option it is ignoring that.
It seems to immediately sleep though. Instead of timing out, the external display goes black, reports a loss of signal and then goes into its own power save mode. So it appears to go to sleep.Yet it is warm in the morning, and the open Terminal sessions, which I would normally expect to break, are not broken.
Okay, so there’s still network communication going on, and you’re used to that terminating.
It shouldn’t be possible, but that could be what’s going on here. This is an interesting one, and I can see how you’d expect your Mac to be a little cooler to the touch if it’s supposed to be sleeping.
Okay, so there’s still network communication going on, and you’re used to that terminating.
Let me check our resources on this. It may be a great opportunity to speak to a senior advisor as well.
I just came back from a trip and during the trip there was no external monitor and I didn't experience this, even though the energy settings are the same.
The network is my home wifi. On my trip, it was my friend's home wifi.
So the external display is really the big variable here I think.
Probably so.
I could just power off the external display before I close the lid as my next test before I go to sleep next time. But I sort of wanted to know what was happening. Especially since I intentionally manually selected sleep.
I’d like to check with a senior advisor if that’s okay with you.
Yes, please do check.
Also - another thing.
I notice my keypad and hand rest - the whole top surface - has become noticeably COOLER since we began our chat. So I'm wondering if there is stuff in the display/lid itself which might be causing the warm temperature, rather than the body (which is what I would have expected with the display off). Or it is just able to "cool better" with the lid open?
That’s another interesting observation. I think either way, the concern still remains whether or not the computer is actually going to sleep. The display of all things should not be producing excessive warmth.
Do you hear any fan noise when you wake your Mac?
Or right beforehand?
Yes, you are correct about the main concern. I thought maybe there was something in the logs I might be able to check to see if it actually was asleep or not.
I have never heard any fan noice from the MBP.
Okay. I just wanted to make sure. My hands-on experience with a new Retina display is limited, I’m not sure what the fan actually sounds like compared to my traditional MacBook Pro. I’ll go ahead and consult with my senior advisor since our troubleshooting steps would indefinitely cause us to get disconnected.
Thanks for your patience as check on this!
I just found this terminal command to check on the last sleep time:
pmset -g log | grep sleep | tail -n 1
It does report that it went to sleep at 2:42 am which sounds right:
8/2/14, 2:42:25 AM GMT+9 com.apple.sleepservices.sessionTerminatedSleepService: window has terminated.
Unless that means sleep ENDED at that time.
Interesting. I’m glad you found that. It’s a little beyond the level at which I know OS X, But I’ll have some answers soon enough.
OK. Take your time.
Thanks, Doug.
I believe I found more information, though it still doesn't explain why the SSH connection didn't break.
This command:
pmset -g log|grep -e " Sleep " -e " Wake "
will report all the sleep/awake occurrences.
For the last few days it reports:
7/30/14, 11:16:09 AM GMT Wake Wake from Standby [CDNVA] due to EC.LidOpen/Lid Open: Using BATT (Charge:99%)66 secs 7/30/14, 11:17:15 AM GMT Sleep Clamshell Sleep: Using BATT (Charge:99%) 10830 secs 7/30/14, 2:17:45 PM GMT+ Sleep Maintenance Sleep: Using BATT (Charge:97%) 11542 secs 7/30/14, 5:30:07 PM GMT+ Wake Wake from Standby [CDNVA] due to RTC/Alarm: Using BATT (Charge:96%) 41 secs 7/30/14, 5:30:48 PM GMT+ Sleep Clamshell Sleep: Using BATT (Charge:96%) 10823 secs 7/30/14, 8:31:11 PM GMT+ Sleep Maintenance Sleep: Using BATT (Charge:94%) 7/30/14, 9:29:02 PM GMT+ Wake Wake from Standby [CDNVA] due to EC.ACAttach/Lid Open: Using AC (Charge:94%) 8/2/14, 2:06:18 AM GMT+9 Sleep Software Sleep pid=78: Using AC (Charge:100%
So (if you can look at that neatly, one line at a time, it shows it was in fact going into clamshell sleep until I manually put it into sleep.
Then at 2:06 am it went into "software sleep".
Then at 2:42 a it went into something called "maintenance sleep"
at 3:30 am it was awakened by CCC (Carbon Copy Cloner) and did not go to sleep again after that.
So maybe:
1. The sleep is quietly keeping the SSH connections alive and,
2. CCC is not properly putting the MBP back to sleep after doing its 3:30 am backup?
Doug, I’m going to go ahead and transfer you over to a Senior Advisor now. They will discuss this with you further. Does that sound good?
Yes, thank you.
You are now being connected to another Advisor. Please standby.
Okay, so your external display is not sleeping?
It is sleeping.
It times out in 15 minutes normally.
After I close the MBP lid.
Just like the energy settings say it should.
And when I did the forced sleep via the power button the external display immediately went black and reported loss of signal and then went into power save mode.
So I assumed it was asleep.
Okay, so, the Mac is not sleeping or the Display?
What I'm trying to find out is if the Mac is sleeping or not. The reason I was prompted to ask was because in the morning after I wake up I notice the MBP feels warm to the touch. I would expect it to feel cold if it was sleeping. Also, a terminal session with an SSH going did not get broken.
Okay, I think I understand now. You are looking for answers about the sleep status of your Mac. I understand your expectation of a cold Mac, and I am here to help.
Thanks. Did you notice my pmset command outputs near the end of my chat with the previous person?
So, In Energy Saver, there is a setting to wake for network Activity.
Yes. It is checked.
However, when not connected to the monitor (like on my previous trip) that was not enough to keep an SSH session going.
Okay, so this would explain to me why the Mac would be warm to the touch. If there is a SSH session active.
Typically those shells would break when the lid was closed.
Okay, with a Display attached, the system expects to operate in Clamshell mode when the lid is closed.
This is all expected
Which prompts two questions:
(1) Even if I force it to sleep with the power button followed by selecting "sleep" from the options and
(2) Even though the pmset output indicated it went to sleep and not into clamshell mode?
I am not familiar with the pmset
http://en.wikipedia.org/wiki/Pmset
In computing, pmset is a command line utility to manipulate power management settings under the Darwin and Mac OS X operating systems. It can assign sleep settings, schedule sleep and wake times, and display power information.
pmset indicated it went to sleep at 2:06 am. Anyway, as I reported above with the previous tech person.
Okay, pmset is not supported by AppleCare, yes it is a Terminal command, but it is there for Developer use
So... where are we left? That you think it was in clamshell mode even though I manually forced it into sleep mode and the logs indicate it went to sleep? I'm just still left not quite understanding what is happening.
I guess I'll just try a test next time with the display powered off and see what happens. I need to go now. Thank you. I will end the chat for now.

Qosmio G20-127: Screen blackout after closing the lid on Vista

Hi,
I have Qosmio G20-127 and I've recently installed Vista Ultimate Edition (32-bit). I managed to bring everything to its place (except the magic buttons, but the drivers are not out yet), but I have a problem that is seriously making me reconsider going back to XP MCE.
When I close the lid of my computer the display naturally goes off, but when I open it up again it does not turn on, but it stays black. And I can't make it turn on again no matter what. I have to turn off the entire computer and that is quite impractical.
Funny thing is that after restart for about 20-30 minutes I can open and close the lid normally, but after a little longer work on the computer the same problem occurs.
The problem persists even after I turned off every action remotely connected to closing the lid.
Does anyone have any solution?

Hi J,
thanks for your help but my BIOS update won't install. I get the message "[Error] BIOS Update is not supported OS. Unsupported OS or service pack is installed."
About the powersaver, I didn't install additional powersaver program as I was told it would conflict with Vista's Mobility Center (FranciscoJr's Guide to installing Vista), but all the options regarding closing lid are turned off (Do nothing option).
There are two more new things I observed and might be indicative of the problem, but I don't know what to make of it.
1. When I close the lid I hear 'disconnected device sound'
2. And the screen sometimes comes back if the s-video cable (leading to my tv) is plugged out (usually it was always in coz I use Q20 as a media center as well)
Of course that made me think that it might be a problem in Graphic Card, but I've installed the most recent driver.
So now I'm pretty much clueless as what to do.

Since upgrading to Mountain Lion, my Macbook reboots after closing & opening the lid

I haven't found any threads as of yet of other users experiencing this issue and wanted to post to see if anyone had any ideas on how to resolve this. Just for grins, I had a spare hard drive and erased the drive and performed a clean installation of Mountain Lion. The problem persisted with the clean installation with no restored data or Bootcamp partition.
I have a 2010 Macbook Pro with a Bootcamp partition. One thing to note, when booting into the Windows 7 partition, I don't have the issue when closing the lid and going into sleep mode.
Thanks in advance for any feedback,
Dan

Thanks for the quick reply. I have tried both suggested articles and will keep an eye out on the system for the next day or two. So far it hasn't rebooted since performing the corrective action.
Thanks,
Dan

Cannot adjust brightness after display driver update on Satellite L855-118

Hi.
I just bought an SATELLITE L855-118 , with ATI graphics today, it was between this and another one, but i know you have problems updating graphic drivers on a Sony-notebooks.
I made a restore point.
So i uninstalled the ATI catalyst and then did an driver sweeper, and re-booted and then installed catalyst 12.6 , installed fine, but my screen went to maximum brightness and i cannot adjust it, the brighness osd appears but the screen brightness does not change.
So i used my restore point.
This time i overwrote the stock catalyst 8.9 with 12.6, just the same cannot adjust the brightness.
Does anybody know how to fix this.
My full spec in the link below.
Satellite L855-118 - Product Specifications - Toshiba
Thanks
John.

This is not going to help you, but I have details on the internals of brightness control on this machine.
On other notebooks I've worked with, the hotkeys generated an event that was directly handled by the firmware (ACPI) that changed the brightness; this was done to avoid putting into the AMD video driver any system-dependent code.
On the L855 the ACPI does not really handle the notification, it just generates another event that is supposed to be handled by the video driver. For more technical details see:
[http://thread.gmane.org/gmane.comp.video.dri.devel/71255]
Now this is where it gets ugly: if brightness control is indeed system-dependent (e.g. you have to poke some random GPIO) then the AMD driver will never support it (it would have to know the details of each and every model in circulation).
The good news - at least for Linux users - is that AMD just published the specification of its ACPI interface:
[http://thread.gmane.org/gmane.comp.video.dri.devel/71697]
I've already done some experiments with it, keep an eye on the thread.
This may (or may not...) lead to a usable brightness control *for Linux*, but the same information *may* be used to create a similar driver for Windows.

I have a new 27"ACD connected to a 27" iMac (2010) and cannot control brightness on the ACD. Also, the option to turn off the ambient light sensor is not available. Tanks for any help.

I have connected a new 27"ACD to a 27" iMac (2010) and cannot independently adjust brightness on the external display. Also, the option for turning off the ambient light sensor is not available. The iMac has the latest updates according to Apple messages. Any help will be appreciated.

No, Detect Displays had no effect. However, I made the USB connection from the ACD to the iMac after the system was on. Following a re-start, all controls are available. Thank you for your response.

IPad, cannot control volume after 8.2 update

After updating my iPad to 8.2 last night, I am now no longer able to control the volume. The volume will randomly go up and down fairly often on its own, and nothing I do seems to prevent this from. I've turn the iPad off and back on numerous time, but to no avail. Any help wold be appreciated.
Thanks.

Hi The Daniel 1983,
Thank you for using Apple Support Communities.
I understand that you are not able to adjust the volume on your iPad after updating. I have a couple of suggestions for you to try. First, take a look at your sound settings. It is possible that the setting to use the side buttons to change volum were changed during the update, see "Change your sound settings" in the following article and make sure the "Change with Buttons" toggle shows green.
Change sounds, ringtones, and alerts on your iPhone, iPad, and iPod touch - Apple Support
If that doesn't work, I would suggest a reset of the iPad, see this article for how to do it.

Video in Timeline cannot be seen after closing/reopening project in Premiere CC

Hello..I am using Premiere Pro CC and i have a problem regarding the playback video...as when i open up my project after 5 minute the video on the timeline can't be seen on the preview monitor but we can hear the audio of that particular video???Please resolve my problem.

Hi,
The error message that you have given occurs mainly when Premiere Pro is not activated properly or even sometimes when Creative Cloud Desktop app is not updated or you are not signed in.
To troubleshoot, first make sure your Creative Cloud Desktop app is updated and you are signed in. Next launch Premiere Pro and sign out and sign back in to Premiere. Next try to open your particular project.
In case you still get the same error, check your hosts file (hosts file location: C:\Windows\System32\drivers\etc).
Let me know the outcome.
Thanks!

Satellite M60-BK3: Cannot get sound after Vista installation

Hi,
I've installed Windows Vista Ultimate Edition (32bits) on my Toshiba Satellite M60-BK3, but I can't get any sound either the correct video settings. I've searched on the internet and it seems that this Satellite family is not supported to be upgraded to Windows Vista :S
Does anyone have any idea of how can I get these drivers in order to make my laptop work fine with Vista??
Thank you.
Rodrigo

Hi
This Satellite M60-BK3 model is not known to me. Where did you purchase it???
Try to install a hardware diagnostic tool to find out what sound chip and graphic card this notebook supports.
Then you could download the drivers from part manufacturer site.
