Hello,

I have a Toshiba Satellite L505D-S5983 Laptop that was working just fine until today, when all of a sudden the keyboard and touchpad stopped working. The external mouse still operates. Is there something really obvious that I'm not seeing here? Appreciate any help. Thanks
Pat

I have the exact same problem with the same unit, does anyone have any suggestions? I have downloaded the driver from toshiba and tried to restore the system to just prior to the malfunction and still no keyboard or touchpad.

Hello and welcome to Bleepingcomputer.

I have a very helpful link for you, this whole web site is for Toshiba laptops and how to disassemble them.

Hope you find this to be helpful.

Bruce.

Bruce - thanks for the link. On a scale of 1 - 10, how difficult is it to get my keyboard and touchpad operational? how far into the dis-assembly do I have to go? I must say that, although I am pretty mechanically inclined, I have never attempted to do any repairs on a computer. From your guide, I don't think I'd be afraid to attempt this endeavor. are there any hidden potential pitfalls that I should be aware of?

Thanks,
A.J.

You would have to exercise extreme caution, so as not to damage any ribbon wires or zero insertion force connecters while dissasembling the laptop.
You also have to protect against zapping any components inside the laptop with static electricity from your body. Ground yourself to a cold water pipe in your house to discharge yourself from any possible static electricity.

I do not know if the issue here is driver related since both the keyboard and touch pad are both not working.
This would indicate a faulty electrical connection between the motherboard and the keyboard pad or a controller failure.

By the way, I will provide you with a link to Toshiba's support web site for this laptop model. The link below is to the pdf version of the owners manual.
