Y40 GPU not working after clean windows install.

I did a clean Windows install since I got a new HDD and I can not get the switchable GPU working again. I have the latest intel and amd drivers from Lenovo installed and both show up under dxdiag. When I try to access switchable graphics settings all I get is a blank page. The game I am playing shows what gpu is being used and it is Intel.
If anyone has any ideas that would be great!
Thank you!

installed 10.4.10 all is well!!! Cool! Tim

HP Photosmart C6300 printer/scanner not working after Snow Leopard install

HP Photosmart C6300 printer/scanner not working after Snow Leopard install
Reinstalling etc does not work - does anyone else have the same problem or a clue as to how to fix this?

Keith,
I got a C6280 and the scanner does not work anymore. I am for 6 days in contact with HP. The last printer driver install form the apple web site does not open the image of HewlettPackardPrinterDrivers.dmg because of an invalid checksum. The skipping of the validation gives and error in the install.

HT3917 My apple wireless keyboard is not working after new batteries installed

My apple wireless keyboard is not working after new batteries installed.

Do you get a steady green light to say there is a connection. If not, are the batteries the right way round. Do you have a monitor to tell the batteries strength. Is there a reading. Are the batteries good quality ones, Duracell, Energiser or Apple rechargeables.

Touchsmart 320-1030 Touchscreen is not working after OS re-install

HDD crashed, and was replaced with new, re-installed system from factory recovery CDs, now touch screen does not work. I have re-installed the drivers to no avail. system Properties says under Pen and Touch: No Pen or Touch Input is available for this Display. It used to work before the hard drive crashed. Is there a setting in the BIOS? or something else I may have missed?
Thanks

My keyboard does not work after cleaning :-(

Hello, I have a MacBook Pro (bought in december 2009) an now the keyboard does not work after I cleaned it. This was on thursday and today it still does not work. Any ideas?

Chances are that you've shorted the terminals on the keyboard, and will need to be replaced… When the keyboard on unibody MacBook Pro's is replaced the whole 'top case' will be done, trackpad etc… Now generally it is highly unlikely that the Liquid submersion indicators will have been activated unless the cloth was saturated with water. Also unless you purchased the AppleCare protection plan your MacBook will be out of warranty and will require an out of warranty repair.
From knowledge out of warranty repair for a top case assembly it's £163 and a level 2 hardware repair is £28

Satellite P305-S8820 - FN key not working after clean install of Windows 7

Hi,
I have a Toshiba Satellite P305-S8820. I recently did a clean install of Windows 7. I have loaded the Toshiba value added driver pack and the trackpad driver but still cannot get the trackpad or the FN key to work.
Any ideas?

Hello John
You are like other millions other users and what you can read is relevant for you but sometimes it works a little bit different. For you it can be useless but sometimes it helps. Fact is that this utility is offered for some notebook models.
Generally speaking you are right and after VAP installation the job should be done but Ive faced the same problem in the past. Sometimes it works well and sometimes not. You will not believe me but in the past I used stuff for Satellite P300 to get all stuff working on Satellite A350. I cannot explain why this happen and it sounds crazy but it is the truth.
You can also try to play a little bit with VAP installation. Try to install VAP for A300/A350/P300. Generally speaking it is the same and if this will not work well you can remove it from the system.

Mail search not working after clean install of 10.5.4 on new 20" iMac

Apple Mail search is not working. Search on "subject line" works, but search on "entire message" does not. For example, searching with "parking" yields NO results, and there are many messages with the word "parking" in their body in the mailboxes. It happens with both "In Box" and "All Mailboxes" checked.
What's going on?
I did a clean install of Mac OS X on a 20" iMac using the Install disk shipped with the machine. Then I ran Software Update. Still, the problem happens, on a clean baseline system.
Argh.

I've had this problem since Tiger. Various solutions have been posted, but none have worked for me. It really cripples Mail--I've used emails as my personal database for years, kind of a history log, which worked great in Eudora but Eudora isn't being supported anymore.
After updating to X.5.5, I can search "entire message" for "All Mailboxes" and find everything including emails in the mailbox I was viewing (often finds 60,000 occurences, but doesn't take very long--it's just incredibly tedious to find the one I want from such an enormous set of results). I can also find everything using Spotlight, outside of Mail. But if I am looking at any mailbox, like Inbox, search "entire message" never finds anything at all. Searching for subjects etc works fine.

Snow leopard app store not working after clean install. Anyone else having this problem?

The App store has stopped working after a clean install of OS X Snow Leopard. The get/install buttons go grey after I've clicked on them then nothing....
It doesn't hang, all the navigation buttons work fine, and I can log into iTunes fine. Just can't buy anything...

Try resetting the App Store and Clearing Cookies.

Lightroom 4 is not working after clean install

Hi!
I have a cloud subscription. Now I've bought a new Mac Pro, installed all applications I need (Premiere, AE, Photoshop) and finally LIGHTROOM 4, but it's the only app that will not work. It always says something like "There is a problem between changing the modules". I can't see any Folders or Pictures.
I've de-installed everything, installed new many times in different ways, but always with the same result.
Any ideas? I'm pretty lost, because I've organized more than 10.000 Photos with it.
My System:
Mac OSX 10.8.2 with latest Cuda drivers. As told before, all the other Adobe Apps are working perefectly.
Meanwhile Lightroom seems lost it's Cloud Connection... it want's a Serial now when I start the Programm
Any ideas are welcome, thanks in advance!
Best regards!
ANDY

Hey ANDY,
Lightroom has to be installed through the Adobe Application Manager to license properly as part of Creative Cloud. Did you install it through Adobe Application Manager after uninstalling- from the shortcut in the Applications folder?
I found this doc for the modules error:
http://helpx.adobe.com/lightroom/kb/error-changing-modules-lightroom.html
I would be curious if you get the same result in a newly created admin account?
10.7 http://support.apple.com/kb/PH4600
10.8 http://support.apple.com/kb/PH11468
If it doesn't happen in the new admin acocunt it might be something here:

Hope that helps,

Keyboard and Touch-Pad Not Working After Having to Install New Hard Drive

I had to install a new hard drive in my HP Pavillion DV9700t that has Vista Home Premium 64-bit. After going through the recovery process with backup disk the built in keyboard and touch-pad do not work. During the installation, an error message came up saying something along the lines of "the drivers are not supported by this verison of windows because they are unsigned." The drivers that had that error were "hpqkbfiltr keyboard filter driver," "HP remote control HID Device," and "hpqkdfilter driver." I tried to update the drivers for the keyboard from the hp website, but the keyboard and touch-pad still do not work.
My question is, where do I find the digitally signed drivers for the keyboard and touch-pad that Vista won't flag and disable?
Help please!

Sparkles,
Thanks for the suggestions.
When dealing with MS Fix It, I was choosing run. Upon further investigation on that site, there really isn't a scan that applies to my issue anyways I tried the .NET Framework repair tool, and that seemed to work. It told me to try re-running what I was having issues with, so I tried running the Windows PowerShell again, but again was faced with the following message "windows update standalone installer encountered an error: 0xc8000247." I went back to the .NET screen and hit "Next" because it didn't work, and that responded by saying they were going to submit logs to Microsoft. I won't hold my breath on that one.
I'm to the point where I honestly don't care anymore. I have no idea what to do, because doing a clean install with the discs HP sent me isn't going to help because they are just recovery discs, and not an actual Windows disk. This is the second hard drive I have had to put into my laptop and use those recovery disks on in the last 3-years. The built-in keyboard hasn't worked during that time frame on either hard drive. I don't think the recovery disks I was sent install properly. Not sure where to go from here. I spent way too much money on this laptop years ago having it custom built to handle all of my drafting programs, so I don't want to just kick it to the curb. I was looking into the possibility of just replacing it, but I cannot stand the Windows 8 interface.
I guess I should have fixed the issue with the keyboard on this hard drive before loading all of my programs. Between the recovery disk install, formatting of the hard drive, and installing all of my programs it took well over 12 hours. Not really looking forward ot that again Then there's shockwave and flash and all of the other goodies that my recovery disks won't restore anyways.
Sorry if this seems like a negative post, but I'm just tired of trying to no avail. Maybe I should just take it somewhere to get it looked at, but I can't see them being successful if the recovery disks won't help anyways.
Thanks for you help,
MadBuch

Keyboard not working after restoring windows 7 from windows 10

Last Friday (7/31/15), I upgraded Windows 10 on my Sony laptop from Windows 7 Home Premiums. My Windows 7 worked fine before the upgrade. After upgrading to Windows 10, I had experienced issues with my Outlook mails (send/receive errors) and other apps (iTunes did not run, Google Chromes did not run, etc.) that I had under Windows 7. With Windows 10, I did not see my iPad or iPhone when trying to connect to my laptop, either.
With these issues/problems, I decided to restore back to Windows 7 (8/4/15). Windows 7 was restored on my laptop, and I am able to see my familiar screen, but my keys are frozen! I tried to navigate by clicking my mouse or hitting any key on my laptop, but nothing happens. I tried to reboot my laptop with different ways below, hoping to resolve the frozen keys but still did not work.
Turn off my laptop and open in "safe mode", "safe mode with network", "safe mode with command", and "start windows normally". (tried many times)Remove the laptop battery, let it sit for 1 - 5 minutes, put back the battery, and turn on the laptop. (tried many times) Please help!!!!! I haven't been able to use my laptop since the upgrade to Windows 10 (July 31, 2015) and restore to Windows 7 (August 4, 2015).

Sounds like you've done everything right. Delete the prefs again, following the instructions here: Replace Your Preferences
If that doesn't work, take another look at what else is running and turn off stuff that you don't need to see if there's a conflict, and wait to see if Bob pops in.
As a last resort, uninstall again, then run the clean script befor you reinstall: Run the CS4 Clean Script
This was a clean install of Win 7, not an inplace upgrade over Vista, right? The upgrades are known to be iffy, so if that's what you did, think about doing a clean install instead.

Secondary monitor does not work after OS X install

My secondary monitor does not work well after OS X install. The image on my secondary monitor is different even the screen svaer image is different and the mouse can not be seen.

Try the easy thing first - NVRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
If that does not work, post back with more info, including the version of Mac OS you are running. How is the external monitor connected, did it ever work, and from what OS X to what was the "OS X install" in your title?
