Several keys in my laptop keyboard don't work: delete, 7, n, b.
What can I do to fix the problem?

Try an external usb keyboard to rule out any problem with the motherboard keyboard controller. If the external works go into device manager and uninstall the keyboard as a device and reboot to let the driver reload and replace the old driver. These are admittedly not real likely to work but cost nothing so worth a try. If none of that works, then we need to discuss a keyboard replacement and for that we need your full model number, color and language of the keyboard.

Thank you for your reply Huffer.
I tried with the USB keyboard, and it actually works. All the keys, including the ones that don't work in my laptop, work with the USB keyboard.
I uninstalled the keyboard from device manager and rebooted my laptop, but the keys that I mentioned before (delete, backslash, # 7, letter "n", and letter "b") still don't work.
What is the next step that I can take?

We are chipping away. There are dozens of HP Envy 17 models all with different keyboard or at least many different ones. Here is how to find the exact model number:

Now we are getting somewhere.
Envy 17-j020us is the model number and I had a laptop in that same model series a couple years back.
Here is the Service Manual:
You are out of warranty, right? Guessing the laptop is close to 3 years old now. You do not have a touchscreen, but you do have a backlight and have no pointing stick in the middle of the keyboard; just a touchpad, right?
If so, this is the part number

See p. 92. Unfortunately, I have some bad news. Keyboard replacement on this model is the most difficult of any model I know of. You come in from the back and actually have to remove the motherboard before you remove the keyboard. It is quite simply going to have to be done by an experienced technician. I would be nervous to do it and I fix laptops pretty often.
You might save yourself some money by buying the keyboard yourself and take it to a repair shop to do the repair.
