Laptop G550 no display when power on

hello sir,
I went for service. they said that the GMCH should be replaced n they will charge me 4400/-.... does GMCH worth so..... i want to know actual price of GMCH???

hi Prash3232,
If the GMCH is causing this issue and i Checked the system board for G550, GMCH is part of the Mainboard.
If you can check with them if it is a whole mainboard replacement then the price you gave (4400) is in your currency then I would say that it's about the same price.
Mainboard for your system is about 80-90 USD converted to your currency thn it will fall somwhere in the same price.
Hope this helps

Spilled water on Laptop- it works only when power cord NOT plugged in.

HP Pavilion dv2000 laptop I spilled plenty of water on the right side where the power cord is. I removed that and took the battery out. (12 cell i think) Dried out the laptop for about a day or so. The laptop is fine except when I'm trying to charge while ON, it automatically turns OFF. So, what gives? How much money do I have to pour into it to fix it?
Thanks!

Water and electricity do not mix (obviously ). When you are plugging in the adapter into your computer, there may be a short somewhere where the water was.
Maybe let it dry out some more, otherwise, I would take it to a local repair shop to look at it (if you're out of warrnty).

Have most recent macbook pro connected to thunderbolt via thunderbolt cable. Occasionally when I close my laptop the thunderbolt display goes black and does not come back on---even in response to keyboard. Help

Have most recent macbook pro connected to thunderbolt via thunderbolt cable. Occasionally when I close my laptop the thunderbolt display goes black and does not come back on---even in response to keyboard. Help

Hello QuinnDev,
Thank you for posting in the Apple Support Communities. It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on. I found an article that talks about closed clamshell mode. You would have to fulfill the following requirements to use your display this way:
Requirements for closed display mode:
Power adapter
External keyboard, mouse, or trackpad
External display
You can find all the steps and the full article here:
Mac notebooks: How to use your computer in closed clamshell (display closed) mode with an external display

I hope this helps!
All the best,

Hi Vaish,
I’d like to help you with this issue as we can try to increase the Brightness of the screen from the power options while plugged in,
And then please if still the same we can try to uninstall the Lenovo Energy management and reinstall it back:
Lenovo Energy Management for Microsoft Windows 8
Lenovo Energy Management for Microsoft Windows 7
Hope the information helps. Let us know.

How can i turn off my laptop display when connected to an external monitor

Hi,
How can I make my laptop monitor turn off when connected to the 27 inch cinema disply? When connected to the Cinema display and the Laptop is open,the display on the laptop shows my wallpaper screen. Is there a way to have the laptop display turn off?
Thanks

I'm having the same issues. Using the following command in terminal does not work for me. After rebooting the laptop screen still comes on.
sudo nvram boot-args="iog=0x0"

23" display looses power when either USB or firewire cables are connected

I was actively using my computer when one of my 2 23" cinema displays lost power. I thought it died and was unplugging everything, when I discovered that it powered back on when both the connected USB and FIREWIRE cables were disconnected from my mac. If I connect either one, it immediately goes black (with no white LED). Any solutions outside of taking the thing in for repair?

I'm leaning toward suspecting the 65w power brick of delivering insufficient power to the monitor to drive the USB/Firewire load. Gonna try a different power brick and see if that makes any difference.

Hpcmpmgr.exe display when shutting down laptop

I originally posted this question under operating systems and software and was advised to post it under "printers". I am new to this site and forum and hope to get some advice on the above mentioned problem. I have a photosmart printer all in one, hp officejet J6480 series, my laptop is a Toshiba Satelitte L300D windows XP. The laptop was purchased new in December 2008 and the printer all-in-one in Feb 2009. I installed the printer and everthing worked fine. The other day when I turned off my laptop I received a message box stating "End program"...hpcmpmgr.exe cannot end...click "end now" to close this program. The only changes made to my system were the usual updates by windows etc. I am using a USB hub and have this printer, speakers, and mouse pointer plugged into it. Since my first post I have tried clicking on the "remove hardware" icon on the toolbar on the bottom right corner and selecting the device to remove it properly but I still get the same display when I turn off my laptop. I would appreciate any suggestions on proper shut down technique to avoid this display. Thank you.

Hi, thank you for your answer!
I was truly troubled about this issue because it was a 'clean' pre-installed system and I didn't do anything to it.
But it's good to hear, that I'm actually the only one having this kind of problem with Toshiba's new 550D.
Anyways: *It seems that I somehow managed to solve this csc-issue by uninstalling Microsoft Essentials and all its components with a removal tool.*
I'd be lucky if I'd found the culprit causing those error messages - if not, I'll try this csc.exe fix tool you just recommended.
Thanks again!

My iphone wont turn on when connected to a laptop or pc,but when its connected to my dock, its shows it need restoration what should i do?

my iphone wont turn on when connected to a laptop or pc,but when its connected to my charging stereo,its shows i need to conect to itunes but then after 10-15 min. it turns off.

Hi Monzairita,
Thanks for visiting Apple Support Communities.
If your iPhone only powers on when connected to a dock, and shows the "connect to iTunes" screen, start with these troubleshooting steps:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Best Regards,
Jeremy

My safari will not open after downloading librooksbas.dylib plug in. message that is displayed when i try and open is "safari quit unexpectedly while using the librooksbas.dylib plug in" i can either re-open or ok the error to which neither work :(

i have tried the terminal code thing where you enter certain words then press enter and it worked but as soon as i restarted it and opened safri the error message apperarewd again my software is OS X 10.9.1

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My Satellite laptop (A305) shuts down when run on the AC charger/adapter

The problem is that my Toshiba _A300 series laptop (A305) shuts down when you try to run it on the AC charger/adapter_. You can boot it with the power cord plugged in and it will get to Windows Desktop and maybe a few minutes more at most before shutting off.
It will boot and _run from battery without problem_, but if you plug in the AC while it is up and running on battery the machine will normally click off instantly and reboot to the message "Windows was not shut down correctly."
The _AC adapter works fine_ reading a steady 19.19 to 19.20 volts with a voltmeter. It also _charges the battery fine when the computer is off_. I have two Toshiba brand batteries and they both work fine.
One interesting thing is that the _computer runs fine on AC when in safe mode_.
I _did a reformat/factory restore_ of Vista to assure it was not software and drivers, and still got the same problem before any external devices had been plugged in.
It has the latest BIOS and I tried resetting it to default values in case anything had gotten changed. It made no difference.
This is _not a heating issue_ because _while it is run on battery I can watch long videos_ without it shutting off. I ran compressed air through the vents just to make sure, but it makes no difference in behavior. Usually with an overheating shut-off, the computer cannot be started until it has cooled some, but these shutdowns are accompanied by an instant reboot.
I have seen on some threads that this type of problem one can work around by disabling one of the processors in Device Manager, but I don't think that is much of a lasting solution or good for the computer.
Has anyone seen this problem before and have you come with a full diagnosis of the problem and a real solution?

I have Satellite A300 and until now everything works OK.
I would like to know what happen when you remove the battery and use notebook with power supply only. Does notebook shuts down again.
If not let OS run and put the battery.
Is the battery recognized properly? Does notebook switch off again?
To be honest I cannot imagine this issue has something with software or background processes. Recovery image you got with your notebook is designed for this certain notebook mode. Recovery image is tested and I dont think preinstalled OS has anything to do with this.
Full diagnosis?
And how to do this? You know very well that diagnosis can be done with diagnostic tools only and such tools have services only. I hope you will find answers but Im 99% sure there is nothing you can do about that. Maybe you should contact service, explain the situation and ask for help.

Blinking display when sleeping.

I just noticed this today, and a search didn't turn up any similar problems. I came back to my mbp after doing something else, and I think it had gone to sleep in power adapter mode. I just have the display sleep and not the cpu when power is connected. The display was flashing off and on at about once/sec. It returned to normal as soon as I entered anything on the keyboard. My wifes Macbook does this occasionally, too.
Anyone have any experienct with this?

Sometimes. I believe it's an interaction between the display being off, the screensaver and the screensaver password mechanism (it's used when you wake a system and it asks for your password).

The BIOS may be set for Fast Boot. Try accessing the BIOS by depressing F2 and then powering on. Disable Fast Boot there if you like.

It's not surprising that you see about 3 GB of RAM. KB929605 applies to all 32-bit versions of Windows.

If i dont use the display when using the GPS and only listen to the voice instructions can that also makes the iphone overheat even if you dont use the display

because when i use the gps app in my iphone 4s in the car my iphone gets overheat so
if i dont use the display when using the GPS and only listen to the voice instructions can that also makes the iphone overheat even if you dont use the display
will that help?

When you use your GPS does your iPhone get hot enough to shutdown? The reason I ask is that I have run my GPS app with the screen brightness set to near max connected to power for hours. My iPhone got hot, but didn't shutdown.

ThinkPad E455 Excessive Battery Drains When Power Off

I bought a new ThinkPad E455 two months ago with AMD processor and I use Windows 7 (64-bit) as my operating system. The problem is, since a week ago, when I turn off my laptop (completely shut-down, not hibernating nor sleeping), the battery looses 14% in less than 24 hours. This problem has never happened before. When I search for solution, apparently my problem is similar to https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E535-High-battery-drain-when-laptop-is-powered-off/ta-p/1249897 and https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E530-Battery-drains-and-power-manager-issue/ta-p/1249887 and https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E440-battery-drains-when-powered-off/m-p/1527086/highlight/true#M18743. It appears that the power drains happened in other type of ThinkPad as well. Moreover, it seems that this problem is not limited to ThinkPad series (e.g: http://www.tomsguide.com/answers/id-2324931/laptop-battery-drains-powered-shutdown.html), and more surprisingly, some of other brands experience this condition as well. My question is, what causes the power drain? I mean, the laptop just worked fine for a period of time (in my case it is two months), if it was trigerred by something, what is it? I looked for the technical updating BIOS solution in http://support.lenovo.com/us/en/documents/ht077068, but unfortunately the series E455 is not in the list. Of course, updating the BIOS using incompatible version is not recommended by the technical support. Please help me.

See https://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface When you think the laptop is powered off it's actually in ACPI Power State S5 with power being supplied to the power button and some of the USB sockets. So, when you shut down the laptop and then removed the power cord, if the BIOS version was lower than 1.13, the laptop was still draining the battery.I followed your suggestion, and it seems solving the problem, thank you. However, another problem arises just recently. When I was playing a game on my laptop, the battery capacity is decreasing when the AC power connected (as described by both lenovo and Windows battery gauge). I post this problem in https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/ThinkPad-E455-Battery-Capacity-Reduced-When-Connected-to-AC/td-p/2106218. Oddly, the problem (seems) does not occur when I quit the game to windows. Why was this happen?
