Build and Design
For those people who aren't already familiar with HP's ProBook laptops, the formula is very simple: Take HP's popular EliteBook line of durable business-grade notebooks and make them more affordable so small and medium businesses can buy them. This is where the new ProBook 5310m comes to the table ... and it's why this is the first laptop with the "ProBook" name on it that we really, really like.
The previous generation of ProBooks all tried to deliver a good balance of features and security at a low price. Unfortunately, those notebooks sacrificed build quality and design (two of the hallmarks of HP's EliteBooks) in order to create a low-cost business laptop. The new ProBook 5310m is the first ProBook that lets you have your cake and eat it too. The 5310m succeeds where previous ProBooks failed by offering a thin-yet-solid magnesium alloy chassis with durable rubberized paint, aluminum display enclosure and a design that looks like a premium business notebook rather than a budget laptop. Sure, like the rest of the ProBook line, the 5310m has a square, industrial-looking exterior, but that's part of the "all business" look that made the EliteBook line such a success.
So how did HP go from an all-plastic ProBook to this new-and-improved design and still make it thinner and lighter than previous models? The answer will probably get a mixed reception among our readers: HP got rid of the optical drive. That's right. There's no built-in DVD or Blu-ray drive with this laptop. Honestly, as someone who frequently travels for business, I can tell you I never use my notebook's optical drive. However, there are still plenty of business travelers who like to watch DVDs during flights, so the lack of a DVD drive might bother some business buyers.

The outer shell of the screen casing, as previously mentioned, is made of aluminum. This is significantly more solid than the plastic-covered screen on older ProBooks, and along with the magnesium alloy bottom chassis the 5310m should survive anything a typical business traveler will throw at it. While I wouldn't recommend standing on this notebook, you could easily stack a dozen or so heavy books on top of the 5310m without any concern for the safety of the laptop.
Tthe 5310m also features the now standard hard drive shock protection in the form of HP 3D DriveGuard which will help to protect your hard drive in the event the laptop gets dropped or violently bumped. HP also includes HP ProtectTools with drive encryption, Device Access Manager, HP Spare Key (a program that helps employees access their computer in case they forget their password), HP Disk Sanitizer, File Sanitizer, and McAfee Security Solution for those small businesses that need reliability and ease of use but don't have the resources of a dedicated IT department.

Screen and Speakers
The ProBook 5310m comes equipped with a 13.3" 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. The LED-backlit panel offers excellent brightness and we typically left the brightness set to between 50% and 70% when using the notebook indoors. 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 between 1366 x 768 and 1280 x 800 is pretty minimal.
Horizontal viewing angles are pretty good 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.

HP generally impresses our editorial staff with the quality of the speakers used in their notebooks. Unfortunately, this isn't the case with the ProBook line. The speakers in the 5310m are good enough for watching a webcast or hearing system sounds, but the built-in speakers sound tinny and lack a good range of highs, middles, and lows. The highest volume settings are loud enough to fill an office with sound for a presentation, but the audio sounds distorted at the highest volumes.
The combo headphone/microphone jack on the 5310m works well with the two different brands of earphones I used during the test. No static or other noise was noticed through the jack besides imperfections in the audio source itself.
Keyboard and Touchpad
The full-size keyboard on the 5310m is a chiclet style design and provides fantastic spacing between keys for typing. 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. On the larger ProBook 4510s and 4710s we noticed some flex in the keyboard above the optical drive, but the keyboard on the 5310m is quite firm and a joy to use.
The individual key presses are quiet without loud clicking sounds as you type. The depth of each key press is excellent, though some people may dislike the flat, chiclet-style keys. Overall the keyboard layout is extremely nice for a budget 13-inch laptop.
The touchpad is very responsive to my touch with a scroll zone on the right side that works exactly as it should. The glossy touchpad texture is okay, but the low-cost material used is sure to develop wear over time and use. The plastic touchpad buttons are about the right size and have the correct amount of depth or throw when pressed. We would have also liked to see a dedicated touchpad disable button (like the ones HP uses on their consumer notebooks) so that you can disable the touchpad if you're using an external mouse ... but that's a minor complaint for what is otherwise a great keyboard and touchpad.
Ports and Features
The 5310m features a good number of ports on all sides, despite the lack of an optical drive, so let us take a brief tour ...
Left side: Here we see the power jack, heat vent, one USB 2.0 port, DisplayPort and Ethernet jack.
Right side: Heat vent, memory card reader, combo audio jack, two USB 2.0 ports, and Kensington Lock slot.
Rear side: The battery and hinges.
Front side: Nothing here but a status light and more heat vents.
Performance and Benchmarks 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. With that said, let's jump into the performance benchmarks. wPrime processor comparison results (lower scores mean better performance): PCMark05 measures overall system performance (higher scores mean better performance): 3DMark06 measures overall graphics performance for gaming (higher scores mean better performance): HDTune storage drive performance test: Heat and Noise 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 and RAM are the hottest parts of the notebook. Battery Conclusion Pros: Cons:
Our ProBook 5310m came with the Intel Core 2 Duo P9300 processor, clocking in at 2.26GHz, and Intel integrated graphics. This gives the ProBook a fanstic level of performance without losing too much in the way of battery life. If battery life is a concern, you can also purchase the ProBook 5310m with the Intel Celeron CULV Processor SU2300 which will give you more tie on battery at the expense of speed thanks to the 1.2GHz low-voltage processor. A 320GB 7200RPM 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 5310m sits near the top of the pack in its class and has more than enough power to handle Microsoft Office or even very basic video work.
During normal use (browsing the web or working on a text document) the ProBook 5310m remained quite cool and very quiet. The exhaust fan wasn't audible even when running performance benchmarks or stressing the CPU and graphics. You won't have to worry about bothering coworkers or clients with unwanted noise coming from your laptop in a quiet office.
HP offers the ProBook 4310s with a 4-cell 41WHr Lithium-Ion battery. The battery life of the standard 4-cell battery is quite a bit better than the previous generation of ProBooks. During our timed tests, with the laptop set to "balanced" mode, wireless active, and 70% screen brightness, the 4310s lasted for 5 hours and 51 minutes. Battery life can also be extended using the "power saver" power profile in Windows 7 ... or you can purchase the 5310m with the Intel Celeron CULV processor.
From the first moment I picked up the HP ProBook 5310m to the last minute while writing this review I kept thinking, "Why didn't HP release this ProBook sooner?" Honestly, if HP had released this notebook at the beginning of 2009 then every other SMB notebook manufacturer would be running scared by now. Unfortunately, HP released several less-than-spectacular ProBooks before this one, and that will probably make some potential buyers overlook this excellent business laptop. The ProBook 5310m finally delivers on HP's original goal to create a more affordable EliteBook. Sure, you have to buy the pre-configured models if you want that lower price, but if you can live without an optical drive then the ProBook 5310m makes a fantastic choice for small and medium businesses.
