Welcome to a laptop battery specialist of the Hp laptop battery
We've already noted that the Atom Z670-powered Slate 2 feels a little slow in use, and this is reflected in the system's Windows Experience Index (WEI) of 2.1 (out of 7.9). That's just a tenth of a point higher than the WEI for the dual-OS (Windows and Android) 10.1in. ViewSonic ViewPad 10pro, which uses the same processor.
The WEI corresponds to the lowest component score, which was for Processor (calculations per second). The top score of 7.2 was for Primary hard disk (Disk data transfer rate), thanks to the SSD. In between were Graphics (desktop performance for Windows Aero) with 2.9, Gaming Graphics (3D business and gaming graphics performance) with 3.0 and RAM (Memory operations per second) with 4.2. Clearly, the CPU/GPU combo is the performance bottleneck here.
The Slate 2 could be a useful vehicle for giving presentations. The speakers on the bottom edge deliver enough volume for a small audience, although at higher levels the sound becomes somewhat distorted.
According to HP, the Slate 2's 2-cell 30Wh lithium-polymer battery such as Compaq PP2100 battery , Compaq Presario R3000 battery (Compaq r3000 battery ), Compaq Presario X6000 battery , Hp Pavilion ZV5000 battery (Hp zv5000 battery ), Hp Pavilion ZV6000 battery (Hp zv6000 battery ), Hp Pavilion DV1000 battery (Hp dv1000 battery )is good for up to 7.5 hours' usage. To test this, we charged up the battery, turned on Wi-Fi and chose the HP Optimized power scheme. Then we looped video until the battery ran out, 4 hours 38 minutes later.
This is clearly a demanding workload, so if you're frugal with the device you could get a full 8-hour day's usage away from the mains. However, we'd advise that you budget for a power boost mid-way through the average day.
The 8.9in. HP Slate 2 is neat and compact Windows 7 tablet that's available with a high-quality stylus and a docking stand. Organisations running bespoke Windows applications whose focus is data capture or mobile use should consider the Slate 2, so long as its small screen, sluggish processor and limited internal storage are acceptable.
We'd prefer mobile broadband as standard rather than optional, though, and battery life could be better. HP might also do well to take a leaf out of Asus's book and offer an affordable keyboard dock.
