Had the same problem on a Toshiba laptop.
Took it to the factory repair center in Jed KSA and then the keyboard went inop under their control.
I had a flight to Jakarta a few days later had the keyboard replaced and a used screen fitted which lasted a few months.
I then bought a HP laptop from Kulor Lumpor and have had it for almost 2 years. Best Laptop I ever bought.
The screens cost more to replace than the laptop is worth.
Not worth the headache, the money I spent trying to save the old one was more than half the cost of the new one.
