There's plenty of connectivity available on the 4510s. To the left you'll find a Gigabit Ethernet port, 34mm ExpressCard slot (though ideally we would have liked a 54mm slot on a machine this size) and two USB ports, in addition to VGA and HDMI for video. HDMI is quite rare on a business laptop, so its inclusion here is a nice bonus.
At the front there's a wireless switch with LED indicator, a card reader that will read the usual suspects (SD/HC, MMC, MS/Pro and xD) and twin 3.5mm headphone and microphone jacks. Finally, on the right we have a further two USB ports, the tray-loading LightScribe DVD-Rewriter and power plug.
Thankfully, in keeping with its business aspirations, the ProBook's 15.6in, 16:9 LCD screen features a matte finish, so glare and reflections are eliminated. We honestly wish manufacturers would apply this approach more rather than the glossy mirrors found on many consumer laptops.
As expected, the 1,366 x 768 screen does suffer from the usual laptop pitfalls, including poor viewing angles with copious contrast shift. Backlight bleed is almost nonexistent and banding is minimal, but small text isn't quite as sharp as we'd like. Overall it's a fairly average screen, but certainly good enough for its intended market.
Likewise the speakers are far from special, distorting even at their fairly low maximum volume and producing painfully tinny bass, but they do the job for Windows sounds and the occasional online video.
Inside you'll find an Intel Core 2 Duo T6570 processor running at 2.1GHz with an 800MHz front side bus. While this CPU is getting a bit long in the tooth, it's certainly more than adequate for any business or indeed multimedia tasks you'd care to throw its way. This is backed by 3GB of RAM, which while hardly generous is more than the 32-bit version of Windows XP Professional needs to be happy.
Yes, you read that right: in the month that Windows 7 is coming out we have a laptop sporting the nine-year-old OS (though a Vista Business upgrade disc is included). Of course that's just the way many business consumers will want it; for one thing, even now there are quite a few printers and other older devices that still don't have Vista drivers. It's worth noting, though, that to get XP instead of Vista Business, you have to be an actual business and are "expected" to order at least 25 systems with the same OS image annually. Windows 7 should also be available when it launches.
