Review on High-Performance 90W AC Adapter Laptop Charger for HP Envy Touchsmart Sleekbook 15 17 M6 M7 Series, Pavilion 11 14 15 17, Stream 11 13 14, Elitebook Folio 1040, Spectre X360 13 15 - Power Supply Cord by Zack Higgins

This charger is not compatible with HP 17t Notebook as stated in the description. You need 150 watts for this, otherwise you'll sometimes hear "submerge, don't charge" and you'll drown anyway. It can work on a laptop with no battery attached, but will only work for a while with certain plugs. The one I got also buzzed during use and got very hot under heavy use (software, video games, whatever). it was taxing on the system). This usually indicates something is wrong with the power converter so I asked for a replacement but ended up sending it back when it failed to charge again. It's a lot cheaper than HP's $130 replacement charger, though, and if you have a smaller laptop it might work as long as it doesn't catch fire. However, problems do arise from time to time, so just check the brick from time to time.
