Wireless

For a wireless solution, Lenovo utilizes the Realtek 8822BE card which is not one we see very often. It’s a typical 2x2:2 configuration with 802.11ac, and a maximum connection speed of 867 Mbps.

WiFi Performance - TCP

The results aren’t pretty. There are good wireless adapters available, and Lenovo often uses them, but this Realtek is not one of those. On a positive note, it was at least very stable during testing, with no disconnections or lost Wi-Fi like we do see on some of the competition. It just isn’t quick.

Audio

If you need a laptop for conference calls, the ThinkPad will work fine, but the stereo speakers which are downward facing do not offer much in the way of range, with almost no bass at all. They don’t get overly loud either, at just 75 dB(A) measured over the trackpad when playing our test track.

Thermals

Lenovo ships the Thinkpad A285 with software that lets you choose the fan profile for a High Performance Mode, or a Quiet Mode.

The fan profile is fairly tame though, even in the High Performance Mode, and even at maximum levels the laptop stays very quite at just 42 dB(A) measured 1-inch over the trackpad. That’s pretty decent for a thin chassis, but as for heat management, it isn’t great.

At 100% load, the system quickly peaks and then throttles down fairly significantly, with a long-term all-core load frequency of just 1600 MHz, well under the 2.0 GHz base of this processor. The temperatures are locked in around 72°C over a long workload, and CPU power draw is well under the 15-Watt TDP. The Thinkpad A285 is quiet, but don’t expect it to be a great device to crunch heavy numbers all day long.

Software

Lenovo is great for not shipping ThinkPads with a bunch of unwanted software, and the A285 is no exception. You can order the A285 with Windows 10 Home or Pro, or through a volume seller most likely any configuration you need.

One piece of software that Lenovo offers on the ThinkPads is Lenovo Vantage, which is a system configuration utility that also serves as a repository to check for hardware driver updates, check the battery condition, and more. The current version of Lenovo Vantage is a great looking application, and clearly some thought has gone into the layout.

One of the nicest features, which seems so small, is that Lenovo Vantage can do a Toolbar by the system tray that shows the current battery percentage. Although Windows 10 offers a battery indicator on the task bar, it’s tiny, and only shows the percentage when clicked on. The Lenovo Vantage toolbar is a better version, with a nice, easy to read indicator.

Lenovo also lets you set a battery charge threshold, which should extend the life of the battery if the laptop is mainly used on a desk. If this is enabled, the maximum charge will be limited to less than 100% to prolong the battery life. The software also has a detection method to determine if the laptop is plugged into an airplane outlet, and if so it will limit the performance to avoid drawing too much power. This is likely more useful on faster ThinkPads, but it’s a nice addition.

There’s also a System Update section which lets you manage driver and software updates from an easy to use pane of glass. It’s a great way to keep the system up to date for security and reliability without having to deal with each component on its own. Lenovo is not alone in offering this, but their implementation is very nicely laid out.

There’s also a hardware section where you can change the display brightness and color temperature for eye care, similar to Windows 10’s built-in Night Mode. Finally, you can scan the system for hardware issues and get support through the app as well.

Overall the Lenovo Vantage software is a nice addition to a business machine, with easy to use interfaces, and genuinely useful configuration options.

    I agree. I have a hihg-DPI Lenovo that I dock, and when I undock, I get blurry fonts in Office because my desktop monitor is old-DPI. I’d have to log out and back in each time I docked and undocked, which is not a convenient thing to do going from my desk to a 1 hour meeting and back. We run Windows 10, but we stay a few versions back for testing/stability (I assume).

    They've had the TN 1366x768 screens for years - I'm using one now (albeit with several other better ones plugged in). It works, but it's pretty bad colour-wise and the low resolution is why sites still need to be designed for such resolutions: they're still sold, new.

    Why do OEMs keep putting capable processors in a chassis with terrible thermal management? If the CPU can't even hit its base frequency under load and yet is *below TDP* then something is very badly wrong with the design.

    That plus the terrible WiFi seems like unnecessary own-goals. It's a shame. AMD have a lot of work to do to catch up on idle power draw, but they're never going to get the investment necessary if their processors only ever get crammed into half-baked products.

    A shame about the idle power draw coupled with a small battery. The screen also sucks but at least it can be upgraded. I was surprised at the performance difference of the iGPUs in the 2500u and 2700u, especially since the CPU tests often ran worse on the 2700u. I wish there were more 2700u laptops available, because that is the sort of iGPU performance I am looking for. And with pretty darn good linux driver support, Ryzen is very enticing (for someone like me).
  • mczak - Tuesday, December 18, 2018 - link

    There is just about zero GPU performance difference between a 2700U with Vega 10 and a 2500U with Vega 8 (ok not quite zero but it's tiny). Just about any significant difference between these two comes down to the actual implementation, that is configured TDP, thermal limits, cooling.
    And apparently Lenovo blew this completely on this notebook.
  • sfwineguy - Tuesday, December 18, 2018 - link

    Sorry to miss something obvious here, but why (per the graphs) did the 2700u underperform the 2500u in some of the CPU tests? Doesn't that confound expectations? Is the 2700u reviewed in another piece that explains how its little brother beats it up in some tests?
  • MonkeyPaw - Tuesday, December 18, 2018 - link

    Probably better cooling in the Lenovo, allowing the CPU to stay boosted higher and more often.

    "It would be nice to see a 16 GB offering, but for office tasks, 8 GB should suffice."

    Oof... That couldn't be more wrong, my dear Brett. The amount of bloatware *cough*McAffee*cough* is just bonkers. 8GB is the *minimum* an enterprise laptop needs nowadays to run a bit less like a hog. For development, 16GB has been the minimum for years (~2013) and now it's moving to 32GB per developer laptop.

    Cheers!

    As a developer unless you are using a lot of Virtual Machines, I don't see much of need to go more 16GB of RAM - However, if you a 3D Graphics Artist, I would believe it will be useful for large scene. most of my machines have 16G. My actual work machine for development has 12G but it older 3rd generation i7.
  • A5 - Tuesday, December 18, 2018 - link

    Meh, it's not just VMs.

    GCC will use as much RAM as you'll let it if your project is of sufficient size, not to mention web browsers, Outlook, etc.
