i had my laptop repaired for overheating and cooling fan issues from a hp service center. since the repair my laptop's touchpad isn't working. after that i formatted the c-drive and installed fresh windows 7 home basic on my 64 bit laptop. i installed synaptics touchpad driver but touchpad isn't showing in device manager. i then connected a usb optical mouse which works fine and then mice & pointing devices is visible in device manager. when i disconnect the mouse, mice & pointing devices disappears from device manager. also in mouse settings there is no tab for touchpad. i also uninstalled the mouse driver and reinstalled synaptics touchpad driver but no use. is it due to hardware problem caused during repair? or is it a driver issue? the touchpad worked fine before repair and i used synaptics touchpad driver earlier. how can i solve this issue?

I understand you are having issues with the touchpad not working after the recent repair. Don't worry, we'll work together to find a solution for you,
To provide you with an accurate solution, I'll need a few more details:
When was the last time it worked (date)?
Have you made any software or hardware changes made on the PC?
Did you install the updates from the official hp website?
In the meantime, let's try these steps here:
First, restart the computer and tap on F10 during restart, once on BIOS screen, move the mouse cursor around to check if it works normally,
If it does, it would confirm a software issue and you follow the below steps if it doesn't work on its a hardware failure and I would suggest a touchpad replacement.
I recommend you to uninstall any generic synaptic drivers showing up for the touchpad (if available) under hidden devices from the device manager:
* Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
* At a command prompt, type the following command, and then press ENTER:
* Type the following command a command prompt, and then press ENTER:
* Troubleshoot the devices and drivers in Device Manager. NOTE: Click Show hidden devices on the View menu in Device Manager before you can see devices that are not connected to the computer.
* When you finish troubleshooting, close Device Manager.
* Type exit at the command prompt.
Note that when you close the command prompt window, Window clears the devmgr_show_nonpresent_devices=1 variable that you set in step 2 and prevents ghosted devices from being displayed when you click Show hidden devices.
And then download a new version of the synaptic drivers using this link: Click here
