About 6 months back my laptop dv4307CL keyboard and touchpad stopped working. But I can connect external keyboard and mouse through USB and able to use the laptop.
When I sent for warranty, they figured there were ants inside and not covered and asked me to replace the motherboard. When I said ok, they changed and said still the keyboard and touch pad not working and asked more money which is equivalent to get a new laptop.
Now is there anyway I can replace the motherboard and make the keyboard and mouse work?
Any idea to replace with less cost would be appreciated.

Re: Keyboard and Mouse stopped working.
Ants in the motherboard, Are they on Drugs ?
The keypad, connects to the motherboard via an additional ribbon cable usually, so it,s not always a motherboard issue.
i think they saw you coming, and just trying to make a fast buck.
If the externals working fine, carry on with them and save your money for another laptop.
When you buy a new 1, take it to whoever told you there were ants, in the motherboard, and bounce it straight off the back of his head.

Try ensuring that the touchpad hasn't been accidentally disabled (Hold down the '[fn]' key and press the F6 key on your keyboard to toggle the touchpad(mouse) to be enabled or disabled.
Have you tried using an external keyboard and mouse?
If the external keyboard and mouse work then we know it is something to do with the built in keyboard and touchpad on your laptop (likely - but not positively a hardware issue). If it does not work then we know that the issue is likely (but again not positively) software based.
This problem is common with Acer Extensa seies . I've an Acer Extensa myself . and i always get this problem . In future i advice you to not use the touchpad . Just use an external mouse to prevent this to happen .
It's possible that something uninstalled the devices from Windows. You can try connecting an external keyboard and mouse, then check the Device Manager to see if it flags any hardware problems.
Another possibility is that the flat cables connecting the keyboard and touchpad to the main board have come loose. To check the cables you need to remove any screws securing the keyboard and pop off the top edge trim to lift the keyboard up.
Go to my computer, right click>properties>hardware tab>device manager, then look down the list for mice and pointing devices, click the '+' sign and right click on your touchpad and select uninstall, do the same on the keyboard line and then restart the pc.
Both touchpad and keyboard will be reinstalled and then ready to use again as it should be back to normal
Have you attempted to use an external mouse? - USB - if so does that work?
if it does - Click on START - Control Pannel - Keyboard (& Mouse Respectively) - Click on the hardware Tab - Select the relevant Key Board, Click on Properties - this will give you a device status - if is is not working properly - click Trouble shoot & follow the onscreen instructions. - If is "Working Properly" click on Drivers - check your driver is updated, or roll back.
If you happend to be on a server and the keyboard and/or mouse have stopped responding - you will need to restart (The Server). Ensure that the Keyboard and mouse are on PS2 connections and not USB - the Severs do not like USB Connected Comms Devices. I have found if there are wireless mouse's &/or Keybourd's &/or any USB connected Mouse/Keyboard, they tend to somehow interfere with each other (i.e. the sever with one of the terminals) - only remedy I have ever managed to make work is restart.
