HP HSTNN-OB89 4400 mAh 8 cells Li-ion Laptop Batteries|HSTNN-OB89 battery
Stay unplugged longer with the new HP ProBook 4311s 2600mAh Li-ion Battery. This 14.4V Rechargeable Li-ion battery can replace the original system battery or be used as a spare. HP computer batteries life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, HSTNN-OB89 battery conditioning and other customer preferences.
The HP ProBook 4710s, like the rest of the new HP ProBook family, is a low-cost business notebook designed specifically for small and medium businesses. this desktop replacement notebook needs to have a good balance of performance, security, reliability and extras all at an affordable price. Most notebooks designed for small and medium business tend to sacrifice build quality in order to help lower the cost of production and lower the cost to customers. On that note, the hp ProBook 4710s battery looks very similar to a HP EliteBook 8730w with all plastic construction, a new keyboard and all black finish.
The HP EliteBook line uses strong magnesium alloy chassis designs and premium internal components. In order to lower the cost and weight of the 17-inch ProBook 4710s, HP constructed this notebook mostly of plastic. The base of the laptop flexes heavily under pressure, the palmrests likewise bow when pressed firmly, and the back of the screen lid is similarly prone to flex. The plastics used in the 4710s will surely survive the typical use and abuse seen by most office desktop replacements, but the chassis might not survive multiple drops off a desk or the kind of abuse we expect the EliteBook series to handle with ease. The key point to remember in this section is that the ProBook 4710s looks pretty nice, but isn’t designed to be a rugged mobile workhorse. Thankfully, HP still offers some good internal components to help make the ProBook 4710s a solid value.Like any good desktop replacement notebook, the one thing that the ProBook 4710s excels at is being big. Pretty darned big, all things considered; the 17.3-inch LCD screen is large enough to begin with, but HP’s quite generous with the plastic bezel around it, leading to a system that measures in at 41.06x27x3.2cm and weighs in “starting” at 3.08kg. Suffice it to say that you won’t be lugging it very far, and it only counts as a “lap” top if you happen to be Robert Wadlow.
HP pitches the ProBook at the business community, and presumably that part of the business community that eschews striking design aesthetics. Compared to some of HP’s recent designs, like the rather stunning Vivienne Tam Edition HP Minis, the ProBook 4710s almost feels like a throwback machine. It’s black on black with black keys and a black outer casing. This is a system that means business and looks business, but more in an “accountant” style than, say a “Richard Branson” one.
HP sells a number of models under the ProBook line, and the 17.3-inch ProBook 4710s is the current top of the range. For a price starting at AU$1899, you get an Intel Core 2 Duo P8700 2.53GHz processor, 3GB of RAM, a choice of 250GB or 500GB hard drives (our test model had the 500GB version), 512MB ATI Mobility Radeon HD 4330 video, 802.11n networking, Bluetooth and gigabit Ethernet. Four USB ports are provided, which almost feels titchy when you consider that the average netbook carries three and is about a sixth the size. HP does fill some of the space with an HDMI-out port, although frankly this particular laptop’s going to dwarf just about any HDMI-compliant source you choose to plug it into.
By the time you read this the ProBook should come with a Windows 7 upgrade option, but our test unit technically came with Vista Business. We say technically, because the default configuration comes with the downgrade to Windows XP Professional pre-installed. If you’re not a fan of Vista — and we could be churlish and say that nobody is — that’s a solid time saver, but if you required Vista it could be a touch annoying. It also features HP’s Disk Sanitizer software for secure file deletion and the usual trial AV software that virtually any notebook seems to come with whether you ask for it or not — in the ProBook’s case it’s McAfee Total Protection.
The ProBook 4710s keyboard fits a notebook of this size, in that it’s mostly quite large, with a deliberately huge space bar row (including CTRL, the function key and Windows key), which we found mostly pleasant to type with. The only real oddity here is that despite the amount of space on offer — which includes allowing a full number pad — the cursor keys are oddly tiny. They’re not impossible to hit, but they’re solidly out of scale to the rest of the keyboard.
