So I have a Toshiba A215-S7418. My cousin dropped it while the power cord was still attached and broke the jack inside the laptop. So I had to take apart the whole laptop to change the jack and secure it back. Then I had to get a new power adapter because the plug was messed up.
Now, everything works fine....but the touchpad. It will not work at all not even the buttons. I looked in the device manager, nothing. It seems like it does not even recognise know the thing is connected.
I'm experienced working with laptops and computers in general, but this is really stumping me!
At first I thought it was a connectivity issue. So I took a look at the ribbon cable from the pad to the motherboard. The connections were starting come off the ribbon, so I bought a new cable. No luck. So I bought a whole new touchpad and button board thinking that would work. NO LUCK!!!!!
I've tried taking the battery out, unplugging it, and holding the power button for 60 seconds. I've tried the FN+F9 thing to lock and unlock the touchpad. I've uninstalled the synaptics software, and reinstalled it. Still no luck.
The only thing I can come up with is an error in the system event log. It is Event ID 6." IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 4, function 0. " It gives the same event error for PCI slots 5 and 6 as well, all function 0. These error never happened before the computer was dropped, taken apart, fixed and put back together.
If anyone has any ideas I'd love to hear them!!
