Question about Acer Aspire 5100 Notebook

2 Answers

Device problems My keyboard and touchpad are failing to work on my notebook. Instead, I'm having to use a cordless mouse and an on-screen keyboard. It's becoming ridiculous, especially having to write pages worth of essays for school. When I go into Device Manager through Control Panel, it says there are problems with Launch Manager and PS/2 Compatible Mouse. I click on Launch Manager, and the Device Status says: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" I click on PS/2 Compatible Mouse, and the Device Status says: "The device cannot start. (Code 10)" As usual, Microsoft is taking its time with giving me a solution, so I was hoping that I could get one from here. I am not the most computer-savvy of people so the more detail in your responses, the better. Thank you in advance :)

Re: Device problems

I'm sorry you're having trouble. It appears that you are having driver issues. You don't mention if the built in keyboard is displaying symptoms of any kind, or if there's any informations with regards to why it doesn't work. Also, you say you are using a cordless mouse, but that would be a usb device (As far as I am aware, I've never seen a ps2 cordless/wireless mouse) If you could provide further info i that regard, it would be most helpful. Thanks, and good luck

The Sony Vaio laptop is typically sold with a touchpad device installed below the keyboard. The touchpad is for navigating the screen and is used like an external mouse. A touchpad can sometimes malfunction for no apparent reason, but there are ways on troubleshooting the device yourself before asking a technician for help. Start your computer as you normally would. Click the "My Computer" icon on your desktop. Go to "C:\ Program Files\Sony\Setting Utility Series." Find and choose the "VCCPointingDevice" folder in the "Setting Utilities Series folder" to open the "Built-in Pointing Device" dialog box. Locate the "Enable" box on the "Built-in Pointing Device" dialog box. Check the box to enable the Vaio touchpad if you wish to use this device. Disable the touchpad if it is interfering with the external mouse. Uncheck the "Enable" box if you have a USB (PS/2) mouse connecting to your Vaio and wish to use that instead of the built-in touchpad. Pick "Yes, I'm Sure" when prompted to activate your choice, then close all the windows. Windows 7 Normal Mode Launch Windows as usual. Go to "Start" > "Control Panel" > "Mouse" > "Pointing Device" to open the Vaio touchpad control center. Uncheck the "Enable" box on the "Pointing Device" window when you wish to use your external mouse. Check the "Enable" box on the "Pointing Device" window when you want to use the Sony Vaio touchpad. Make sure the external mouse is not interfering with the touchpad if you have one connected. If so, unplug the mouse from your computer. Click the "OK" button at the bottom of the "Pointing Device" window. Close all other windows. b> XP and Vista Safe Mode b> Restart your computer. Press the F8 key before the Windows welcome screen appears to enter Safe Mode. Click "Start" > "Control Panel" > "Add/Remove Programs." Find and delete all software for mice and pointing devices. Restart your computer in normal Windows mode. Proceed to next step if the problem persists. Restart your computer in Safe Mode. Right click the "My Computer" icon on the desktop. Choose "Properties" on the drop-down list. Pick the "Device Manager" tab in the Properties window. Select the "Other Devices" folder and click on the "+" sign besides it. Delete all the devices under this "+" sign by clicking on the "Remove" button next to each of the items. Restart Windows in Normal Mode. Once Windows is operating, there will be a "New Hardware Wizard" pop-up that will load all the necessary drivers for the touchpad, mouse and other pointing devices. This should fix the corrupt driver for your Vaio touchpad. b> Windows 7 Safe Mode b> Reboot your computer and press the F8 key before the Windows welcome screen appears to enter Safe Mode. Go to "Start" > "Control Panel" > "Device Manager" > "Mice and other pointing devices." Click the touchpad icon. Choose the "Driver" tab and press the "Uninstall" button. Press the "OK" button to confirm. Restart Windows in Normal Mode. Go to "Start" > "Control Panel" > "Device Manager" > "Mice and other pointing devices." Choose the "Driver" tab and press the "Update" button. Press the "OK" button to fix the touchpad software. Hope this help.

Mouse pad stalls and i see a little red light on the mouse pad....i have a compaq laptop but not sure what do i disable thi feature so i dont have to use a physical mouse

The little red light is likely from the red LED underneath your optical mouse. If the mouse cursor/pointer on the screen is jerky, it may mean the mouse pad is dirty and/or if the mouse is wireless, its battery is low and should be replaced. Most laptops have a touchpad as part of the keyboard. If you want to use that instead of a physical mouse, just put the physical mouse away and use the touchpad. Both should be active unless the touchpad was disabled. If the touchpad is disabled, you can re-enable it by clicking on control panel > mouse > device settings tab > enable button.

If you have got a usb mouse plug it into your computer then go to control panel>system>hardware>device manager and go to pointing devices. Right click on the + sign next to keyboard and touchpad, click on uninstall. Then reboot your machine, take the usb mouse out. Windows will reload the correct drivers for the keyboard and touchpad as new hardware and your problem should be resolved.

I hope this helps

First of all, check in the Device Manager if you find any yellow ! marks indicating that the drivers are not properly installed or corrupted.
If you find any entries, try reinstalling those drivers by right clicking on the entries with yellow ! mark and selecting Update Drivers.
Additionally, try reinstalling the drivers for the Keyboard and Touchpad from within the Device Manager by following the steps listed below :
Please follow the steps to go to Device Manager :

Right Click on My Computer and select Properties in the list.
Now go to Hardware tab and click on the Device Manager button.
Device Manager window opens in a seperate window.
Now click on the [+] mark next to Keyboards to expand the tree.
In the list that appears, right click on Standard 101/102-Key or Microsoft Natural PS/2 Keyboard and select Uninstall.
Now, restart the computer once the uninstallation is completed so that the default keyboard drivers will be automatically reinstalled.
Now, go back to the Device Manager and click on the [+] mark next to Mice and other pointing devices and if you find any entry with Synaptics Touchpad pointing device, right click on it and select Uninstall and restart the Notebook.
Now, download the Touchpad Drivers from the Notebook for XP from the link below :

Copy and paste the link in the address bar of a new internet explorer window and press Enter.
Save the file in My Documents or Desktop and double click the file once it is saved.
This will install the Touchpad drivers in the Notebook.
Now, try removing the USB keyboard and mouse to use the Keyboard and Touchpad of the Notebook.
If you are still unable to use the Keyboard and Touchpad of the Notebook, probably, there are internally damaged....need to get them checked by technicians.
