Keyboard issues not resolved

I've had my laptop for just short of 2 years.  From the beginning the keyboard has not worked properly.  The cursor decides to move around whenever it feels like it causing me to overwrite text.  I have to move the cursor back to the of the paragraph to continue typing.  I thought it was because my hand might be hitting the mouse pad but I've made an effort to be sure that's not happening and I'm still having a problem.  I had the keyboard replaced a few months back and it didn't improve much.

Zoom calls keep disconnecting and microphone drops out.  I've had to use an external microphone.  Same thing when I did a Microsoft Team meeting.  I had to ask the participants to wait while I dialed in instead.

Then there's the touch screen problem.  It decides to work when it feels like it which is usually for a short time after I reboot it.

I bought a Dell because I thought the brand was reliable.  I can't believe I have to replace this laptop already.  I had my HP laptop for 5 years.  Very disappointing.
