Dynabook Portege X30L-K – Top 5 Pros and Cons

Toshiba’s laptops live through Dynabook, a new company that’s majority owned by the biggest manufacturing giant in the world: Foxconn. We’re telling you this, as it shows that Dynabook certainly has the backing and capacity to become a very big player in the laptop space. They certainly have the hardware to do so, as today’s Portege X30L-K shows off that their business laptops have a premium feel, tons of features, and good performance out of the Alder Lake processors.

Today we’re giving you a quick overview of the Dynabook Portege X30L-K.

Dynabook Portege X30L-K: Full Specs / In-depth Review

4 reasons to BUY the Dynabook Portege X30L-K

1. Design and build quality

On the outside, the Dynabook greets us with a magnesium chassis that’s incredibly light, with a weight of only 0.90 kg, making for one of the most compact 13.3-inch devices that we’ve tested. It’s also pretty thin, at just 17.9 mm. Dynabook states that the laptop is built in compliance with the MIL-STD-810H durability tests, which include a lot of different things, like drops, shocks, and exposure to extreme temperatures. Still, the lid bends like crazy, probably because it’s made of plastic. The magnesium base is a lot tougher, which isn’t that hard to achieve. We really wonder how much extra it would cost to get a magnesium lid.

Due to the low weight and small footprint, the lid doesn’t open with one hand. Still, it features thin bezels, with the top one housing an HD webcam, a privacy shutter, and an IR sensor for facial recognition. As for the base, it has a spill-resistant keyboard and an optional backlight, which we took in a heartbeat. Typing on it feels pretty good, thanks to the surprisingly long key travel and clicky feedback. It also has a pointing stick, which Dynabook calls an AccuPoint. It comes in blue color and works with the buttons above the touchpad. They don’t have the most tactile feel, which is common with other laptops in a similar situation. On the other hand, the touchpad is super responsive and accurate. However, due to the position of the fingerprint reader, the upper left corner of the pad is left unusable.

2. Display quality

The Full HD IPS display on the Dynabook is fantastic, offering high brightness and excellent viewing angles. To give you a bit more detail, it peaks at around 548 nits, which is absolutely rad, giving even OLED screens a run for their money. The contrast ratio is quite high as well, at 1740:1, which means pretty deep and dark blacks. For the Creators among you, the laptop shows 98% sRGB coverage, producing punchy and vibrant images.

The color accuracy of the panel gets into really good ranges, thanks to our Design and Gaming profile, which lowers the dE value down to 0.7. Here are the results of our color accuracy test with the stock settings (left) and with our profile applied (right).

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.


Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

3. Battery life

The laptop comes with a 53Wh battery pack, which lasts for 16 hours and 23 minutes of Web browsing, or 12 hours and 11 minutes of video playback. Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with.

4. I/O

The port selection of the Dynabook is incredibly rich for such a small laptop. You get two USB Type-A 3.2 (Gen. 2) ports, two Thunderbolt 4 ports, an HDMI 2.0 port, a MicroSD card slot, a LAN port, and a 3.5 mm audio jack. There are some optional ports, including a SIM card slot and a SmartCard reader.

1. Upgradeability

The one miss of the laptop is pretty excusable, due to its portable nature. Almost all 13-inch machines come with soldered memory, but the fact that you can get up to 32GB of LPDDR5 RAM is pretty reassuring. For storage, there’s one M.2 slot that supports Gen 4 SSDs.
