Lenovo has quietly published specifications of its ThinkPad E485 and ThinkPad E585 laptops based on AMD’s Ryzen Mobile processors on its website. Coming in classic black chassis and featuring ergonomic keyboards, the new notebooks are the first Ryzen Mobile-powered PCs aimed at the SMB market segment. The new ThinkPads are equipped with a dTPM 2.0 chip and are offered with various Lenovo services not available with consumer computers.

Lenovo’s ThinkPad E485 and ThinkPad E585 notebooks will be offered in various configurations targeting different a wide range of price points. Different configs will be based on AMD’s Ryzen 7 2700U with the Radeon Vega 10, Ryzen 5 2500U with the Radeon Vega 8 or Ryzen 3 2200U with the Radeon Vega 3 APUs. The laptops can be equipped with up to 32 GB of DDR4 memory using two SO-DIMMs likely running at 2400 MT/s. As for storage, the systems may feature a 512 GB PCIe/NVMe M.2 SSD, a 500 GB HDD, a 1 TB HDD or a combination of an SSD and a hard drive.

The new AMD Ryzen Mobile-based ThinkPads are generally identical, but as their model numbers suggest, the model E485 has a 14-inch screen, whereas the model E585 features a 15.6-inch display. Speaking of displays, the manufacturer plans to offer two antiglare LCD options with its ThinkPad E485 and E585 laptops: one with a 1366×768 resolution, another with a 1920×1080 resolution. Apart from monitors, the laptops feature slightly different keyboards. The 15.6-inch versions feature a full-sized keyboard with a numpad, whereas the 14-inchers come with a classic notebook keyboard layout. Like other ThinkPads, the new models E485 and E585 are equipped with ergonomic keyboards featuring trackpoints and trackpads.

Moving on to connectivity of Lenovo’s ThinkPad E485/E585 notebooks. The notebooks are outfitted with a 1×1 802.11ac + Bluetooth 4.1 controller, a GbE port, a USB 3.1 Type-C header (that is used for data, power, display, and docking connectivity), two USB Type-A (3.0 and 2.0) headers, an HDMI output, a micro SD card reader, a 720p webcam, a TRRS audio jack for headsets, Dolby Advanced Audio-badged speakers, a microphone array, and so on. The systems are outfitted with a discrete TPM 2.0 chip to enable support for various security applications. Meanwhile, only select ThinkPad E485/E585 SKUs will feature fingerprint readers, so biometric security will not be pervasive across the whole range of these laptops.

Lenovo says that both AMD Ryzen Mobile-based laptops come equipped with a 45 Wh battery rated for 9-hour operation. With its larger display I would expect the E585 to consume more power than the E485 and therefore offer a shorter battery life, but interestingly Lenovo rates both at 9 hours. The good news is that the E585 can accommodate a larger battery pack and therefore offer a longer battery life.

Next up are dimensions and weight. At 21.9 mm z-height, the 14-inch ThinkPad E485 appears to be slightly thicker than the 15.6-inch ThinkPad E585 that has a 19.95 mm z-height. As for the weight, the smaller E485 weighs 1.75 kg and is noticeably lighter than the E585 that weighs 2.1 kg. Neither of the Ryzen Mobile-based ThinkPads can be called thin-and-light, yet keep in mind that these systems feature metallic skeletons and come in chassis made of thick plastics, so they are pretty rugged (not ThinkPad X1 kind of rugged though).

If you want to get a thin-and-light laptop featuring an AMD Ryzen Mobile, you should probably take a look at the Ideapad 720S that comes in a 13.6-mm thick aluminum chassis and weighs around 1.14 kilograms (since this is a consumer model it comes with Windows 10 Home and without dTPM 2.0 though).

The new Lenovo ThinkPad E485 and ThinkPad E585 notebooks are expected to be available in the coming weeks. When it comes to pricing, it is set to vary greatly. There will be very affordable laptops powered by AMD’s Ryzen 3 2200U APU and featuring hard drives along with ‘HD’ displays that will probably retail for ~$600 or less, whereas the premium machines based on AMD’s Ryzen 7 2700U and accompanied by UHD panels and dual-drive storage subsystems will cost considerably higher.

    The market that these ThinkPad targets do not need a 4K screen. Most, if not all of the office laptops in my company the DELL E7xxx series and all of them are 1080p screens for the past 3 years. In addition when working in the desks, we have a dual 1080p monitor set up from 21" to 24" connected to the dock where in the laptop lands. Originally they had touch screen but now decided it is too much of a problem and now non-touch screen.
    Similar things I have noted with my friends working in other offices.
    Infact looking at the choices provided Lenovo has been pretty good.

    a) Dual channel SO-DIMM possible with full supported speed of 2400MHz
    b) Expandable battery pack
    c) 512 GB NVMe SSD
    d) Dual storage with 7200RPM HDD

    Further for the people on the road. 1080p can guarantee a far higher battery life than 4K could ever do..

    In my opinion this is the best and most balanced laptop that AMD can ask for and it should be openly advertizing in its Facebook feeds where in it is currently pushing the DELL inspiron 2 in 1s which use a late 2016 chassis while the newest Core models sport a 2018 chassis and less-bezel screen.....

    The market that these things are in is oversaturated already. Having a sku in this range is just to get some filler, minimum effort and if you're lucky some call centers will buy a few hundred of them for logging tickets.

    Ask yourself why Macbook Pro is considered a gold standard for battery life, but uses a much higher than 1080p screen, and comparable hardware to other devices.. Power consumption is a red herring, 4k monitors are power competitive with other devices in the same size ranges.
  • Tams80 - Wednesday, April 18, 2018 - link

    768 is rather sad, but there is some old software out there that is need (yet the support for it has gone) that just doesn't look good at all on higher resolutions.

    1080p is absolutely fine.
  • ToTTenTranz - Wednesday, April 18, 2018 - link

    Are these using the normal Ryzen Mobile or the Ryzen Pro Mobile?

    The mention of TPM 2.0 makes me think it's the former, which would make these the first Ryzen Pro laptops in the market.

    Or do the Pro have embedded (probably just enabled) TPM 2.0, so they wouldn't need a discrete chip for it? Info on that seems hard to get..
  • lefty2 - Wednesday, April 18, 2018 - link

    It's not Ryzen pro, that hasn't been released yet
  • 0ldman79 - Wednesday, April 18, 2018 - link

    That 32GB of memory limit looks suspiciously like single channel memory...

    Why do they all keep doing that to AMD?
  • IntelUser2000 - Wednesday, April 18, 2018 - link

    The Intel E480/580 is single channel too. It's not unique to AMD, its what manufacturers do.
  • HStewart - Wednesday, April 18, 2018 - link

    Yes and also Intel version does not have 4K - people just want more but they don't want to pay more - so manufactures don't give them more
  • Eletriarnation - Wednesday, April 18, 2018 - link

    Why do you think it's single channel memory? Lots of laptops have 2 channels, 1 slot each which would come out to 32GB with DDR4.
  • lefty2 - Wednesday, April 18, 2018 - link

    "Memory Up to 32 GB DDR4 (2 DIMM)"
