Communication

Our review unit is equipped with Intel's Dual Band Wireless-AC 7265 WLAN module. It supports 2.4 and 5 GHz networks, has two antennas and reaches theoretical transfer rates of up to 867 Mbps. Bluetooth 4.0 is already integrated. Other supported features are Intel's Wireless Display technology and Intel's Hotspot Assistant. We were able to measure transfer rates of 3.1 MB/s up to 18.25 MB/s in combination with a Fritz!Box 7490 depending on the distance, but our individual setup environment should only be an indicator. We had no problems with connection drops or other anomalies during the review period. The communication features are rounded off with Gigabit-Ethernet, a dual-array microphone as well as a 720p webcam. The camera is sufficient for well-lit rooms, but the pictures will suffer from signal noise in darker environments, which will affect the quality significantly. However, the quality is decent for video calls in normal environments.

Other WLAN and WWAN modules (all M.2) are available. The integration of a WWAN card (HSPA+ or LTE) after the purchase is not a problem since all the necessary antennas are already integrated.

Security

Fingerprint reader, SmartCard reader and a Trusted Platform Module (TPM 1.2) and the usual password and software protections are typical for a business device. A Kensington Lock preparation is obviously available to protect the notebooks against physical thefts with the corresponding cable lock. This theft protection will probably be especially useful at expos, lecture rooms or meeting rooms.

Accessories

One important aspect of expensive business notebooks is the comprehensive list of dedicated accessories. Docking stations, batteries and modular drive bays for some devices are typical expansion possibilities. Lenovo is traditionally well-prepared in this area and offers interesting products. Lenovo lists three different batteries for the W550s, which can be changed during operation thanks to Lenovo's Power Bridge technology. In addition to the supplied 72 Wh battery of our review unit, you can also get a 44 Wh module as well as a 23 Wh battery that is flush with the chassis. Docking stations are a good solution if you want to use the notebook on your desk to simplify the attachment of peripherals. For example, Lenovo's ThinkPad Ultra docking station (40A20170EU) has 4 display ports including DVI and VGA.

Maintenance

The Lenovo ThinkPad W550s does not have traditional maintenance hatches, but the expandability and maintainability are still good. The screwed bottom cover can be removed in a few minutes that gives access to all the major components. RAM, storage solution, wireless module, M.2 SSD or the fan can be reached easily. As usual, Lenovo's Hardware Maintenance Manual for the ThinkPad T550/W550s explains which components can be replaced by the user and a step-by-step guide. The models from the current T/W-series do not offer an optical drive or a modular drive bay.

Warranty

Lenovo offers a warranty period of 36 months for its W-series, which is quite the standard for business devices and workstations. No less important are several options to purchase additional services and warranty extensions. An extension of the basic protection to a 5-year on-site service (5WS0A22893) is currently available for around 170 Euros (~$186), and a 4-year on-site service on the next business days + accident protection + 3-year sealed battery (5PS0H20182) costs almost 280 Euros (~$306).
