Welcome to a laptop battery specialist
of the Hp laptop battery
As I mentioned, the 15t's chameleonlike touchpad is visually stunning, but not very practical. The touchpad is in a slight depression and has the same glossy makeup as the rest of the keyboard deck, both of which made it difficult to navigate precisely.
Pinching to zoom was harder than I expected, and I was unable to perform common Windows gestures such as swiping from the left to switch apps -- fortunately, the latter is no longer an issue with Windows 10. It didn't help that the two click buttons felt stiff and cheap.
Fortunately, my frustration with the 15t's touchpad was offset a bit by its excellent keyboard with batetyr like Hp AT901AA battery, Hp HSTNN-DB0G battery, Hp HSTNN-I71C battery, Hp Mini 5101 battery, Hp Mini 5102 battery, Hp 579027-001 battery, Hp HSTNN-N50C battery, Hp HSTNN-IB72 battery, Hp Pavilion-dv4 battery, Hp Pavilion-dv5 battery, Hp Pavilion-dv6 battery, Hp Pavilion-dv6t battery. The notebook's black island keys are wonderfully snappy, and include a full number pad as well as handy function buttons for volume and brightness control. On the Key Hero typing test, I chopped away at a fast 85 words per minute with 96.6 percent accuracy (compared to about 80 wpm and 95 percent accuracy on my usual keyboard), and never felt a bit of discomfort.
It probably won't top your smartphone selfies, but the 15t's webcam takes perfectly serviceable photos. The snapshots I took were a little blurry and had a bit of an orange glow to them, but there was nothing that would make my Skype friends think I've turned into a pixelated monster.
There are a handful of CyberLink media apps for editing photos, videos and burning DVDs, as well as Snapfish, which lets you order prints of your digital photos. On the first-party front, you get HP Connected Drive for sharing content across your laptop and mobile devices, as well as Connected Music for playing local tunes and streaming live radio. However, with more widely used apps such as Google Drive, Dropbox and Spotify out there, HP's offerings don't seem all that useful.
You might find something useful out of the dozens of extra apps loaded onto the 15t, but I personally was overwhelmed with the amount of clutter.
