Re: inspiron 5520 touch pad and keyboard issue

Hi jerins,

You may try installing the updated Touchpad driver from Here and see if it helps.

Also, for the keyboard issue, please check for dust in keyboard keys. Try using compressed air can to clean the keyboard.

You may also try reseating the keyboard. For step by step instructions on replacing/installing parts, you may refer to Owner's manual Here.

Note : Please follow the safety instructions given in manual before replacing/installing parts.

If the issue persists, keyboard and touchpad replacement might be required. 

If your system is in warranty, you may provide the service tag of the computer and the name as it appears on the account via private message (click my username and then click Start Conversation) so that I can check the further course of action.

If the warranty has expired, you may contact Out of Warranty department on 1-800-288-4410 (applicable for USA). Let me know if you are in a different country.

Hope this helps.

Thanks & Regards,
Sundeep B
