HP has the crappiest customer service of all computer companies. They had me on the phone for over 70 minutes, using Remote Assistance to try to "fix" a mouse that cost less than $10. I know the price of them, because RiteAid sold the very same one for that price.
Now, why would they waste that much of their (& my) time, trying to save that much money? Naiya, I highly suggest that you go the chat route, or if you bought the keyboard from a local retailer, try to exchange it. Many stores have a 30 to 90 day exchange period. Plus, if you bought it with a credit card, you have additional protection.
Whatever you do, don't allow HP's so called "technicians" take over your PC to "fix" this keyboard. Demand an exchange. The reason that I say this, after that "tech" (I'm biting my tounge here) finished his "diagnosis & repair", my PC wasn't left the same. I had to revert to the last image that I had made to restore proper PC function.
Wonder why HP ranks last in customer satisfaction?
