HP ProBook 4510s Review

Build and Design
The HP ProBook 4510s is a business notebook designed to meet the needs of small and medium businesses ... in other words, it needs to have a good balance of features and security at a low price. That said, small and medium business notebooks tend to have a very basic build and deign in order to help bring down the cost of production. At first glance, the ProBook 4510s looks very similar to a HP EliteBook 8530p with a new keyboard and all black finish. Unfortunately, the design similarities stop there.

HP received much praise for the strong magnesium alloy chassis used in the EliteBook series of business notebooks. Unfortunately, in order to lower the cost and weight of the notebook the ProBook 4510s is constructed mostly of plastic. The base of the laptop flexes heavily under pressure, the palmrests likewise bow under the weight of your wrists, and the back of the screen lid is similarly prone to flex. The plastics used in the 4510s should hold up fine if the notebook is being used as an office desktop replacement, but the chassis might not survive multiple drops off a desk or the kind of abuse you expect from a mobile workforce. On the bright side, the new keyboard is pretty firm except for a very minor amount of flex around the directly above the optical drive (more on that later). The key point to remember in this section is that the ProBook 4510s looks pretty nice, but isn't as rugged as more expensive business notebooks.

Screen and Speakers
The ProBook 4510s comes equipped with a 15.6" anti-glare display with a 16:9 widescreen ratio. At 1366 x 768 pixels, this 720p high-definition display is perfectly usable and features good color and contrast. We know many people are concerned about the transition from 16:10 to 16:9 ratio screens (because this means less vertical resolution) but the difference is so minor that the vast majority of notebook users will never have a problem.

Horizontal viewing angles are quite impressive and you only start to notice some color shift after you get 75 degrees off center. Vertical viewing angles are only average as the screen begins to wash out from above and colors begin to invert from below after about 45 degrees in either direction.

Keyboard and Touchpad
The full-size keyboard on the 4510s is a completely new design for HP and provides fantastic spacing between keys for typing as well as a dedicated number pad (a major plus for businesses that use their computers for number crunching or data entry). Each key is relatively flat with a nice matte texture and the keys sit above a glossy black support frame. The support frame surrounding the keys is quite firm thanks to the design of the chassis which adds additional support for the keyboard. The only obvious area of flex in the keyboard is when you press on the number pad keys. Keep in mind, however, that we received a pre-production unit, and HP claims that the production units shipping to customers have even better support against flex.

Performance and Benchmarks
Our pre-production ProBook 4510s came with the Intel T6570 processor, clocking in at 2.1GHz, and Intel integrated graphics. Discrete graphics will be available at a later date, but discrete graphics will obviously increase the cost of the notebook. A 250GB 5400 RPM hard drive was also included, which helped applications load without much lag. This notebook didn't really exceed our expectations in terms of performance, but the 4510s has more than enough power to handle Microsoft Office or even very basic video work.

The obvious bottleneck in terms of performance here is the use of Intel graphics, but considering the small and medium business buyers interested in this notebook don't care about the ability to play video games or edit HD video, this isn't a major concern.

Heat and Noise
During normal use (browsing the web or working on a text document) the ProBook 4510s remained relatively cool but not very quiet. The exhaust fan seemingly runs a full blast when the notebook is plugged in, so your coworkers might hear what sounds like a distant hair dryer in a quiet office. When doing tasks that stress the processor and graphics, the laptop's fan works hard to keep this laptop cool. This is something of a mixed blessing in that while noisy, it helps to lower the internal temperatures and helps extend the life of your notebook components.

Finally, we recorded the following external temperatures using an IR thermometer after running two consecutive PCMark05 benchmarks. This should serve as an indicator of how hot the notebook will get after about 30 minutes of serious use. All temperatures are listed in degrees Fahrenheit. It's obvious that the bottom of the notebook near the wireless card, processor, and graphics are the hottest parts of the notebook.

Battery
HP offers two different batteries with this notebook. The base configuration the ProBook 4510s comes with a 6-cell 47WHr battery while the $749 configuration comes with the 8-cell 63WHr battery. The battery life of the extended life 8-cell battery is a little better than average, but not amazing. During our timed tests, with the laptop set to "high performance" mode, wireless active, and 80% screen brightness, the 4510s lasted for 5 hours and 10 minutes with a power draw of about 11.1watts. Battery life can also be extended using the "power saver" power profile in Windows Vista.

Conclusion
The HP ProBook 4510s is a solid, though not overwhelmingly impressive small and medium business notebook. Compared to similar notebooks like the Dell Vostro 1510 and 1520 or the Lenovo ThinkPad SL500, the ProBook 4510s is more impressive than the Dell and is either better or worse than the ThinkPad depending on configuration. Whether you're a small business owner looking for a low-cost notebook for yourself or a medium business needing desktop replacements for a few dozen employees, the ProBook 4510s will get the job done.

Still, things like the plastic construction, uncomfortable touchpad design, and difficulty of upgrades might give potential buyers reasons to reconsider a purchase. Additionally, the fact that HP charges almost twice the price for custom configurations (CTO) means that business buyers are almost forced to choose pre-configured models.

Bottom line, the HP ProBook 4510s is a fine notebook for its intended market, but if HP made a few simple changes to the design and purchase options then business buyers would have even more reasons to buy this laptop.

Pros:

* A great price for a 15.6" business notebook
* Nice keyboard ... despite some flex
* Attractive design and relatively light weight

Cons:

* Not-so-great build quality
* Custom configurations are overpriced
* Touchpad buttons are just plain horrible
* Too difficult to upgrade
