i'm using a HP 32 laptop, it's about 6 months old: somewhere in the last 3 months my back and forward buttons as well as my delete and print screen button stopped working: and i cannot for the life of me find out why and what to do about it. Sometimes if i open word and obsessively press on the back button for a long time it wakes these buttons up, but only for a few minutes. then it goes back to sleep.
Its possible it could be the keyboard. Have you contacted HP? I would recommend doing so since you mentioned that you have only had the notebook for 6 months. If you need any assistance with contacting HP please email me at email@example.com with your contact and product information. Please include Attn: Veroncia-Tom's in the subject line.
