The Dynabook Portégé X40L-K is a lightweight business laptop that looks great and performs well, but it does have some shortcomings, such as its webcam. The Dynabook Portége X40L-K is a high-end business laptop that doesn’t try to do anything too fancy, instead focusing on perfecting the basics. In that sense, it did its job. This is an ultralight laptop that offers almost everything you need to have a good experience. I really like this laptop. It has a beautiful display, the keyboard is excellent, and it looks good while still being discreet and professional. Even the speakers are very loud, perfect for media consumption or phone calls. Dynabook provided the Portégé X40L-K for this review. However, the company has no input into its content and does not provide any form of compensation for its production. Design: Super light and looks great
The Dynabook Portégé X40L-K comes in a dark blue that’s subdued but unique enough to stand out
It uses a magnesium chassis, which is very light and easy to carry
Business laptops have always looked a bit boring, and based on my past experience, the Dynabook doesn’t do much to change that perception. Thankfully, with this model, things are a little different. The Dynabook Portégé X40L-K comes in “Tech Blue Metallic,” which means it’s dark blue. It’s bright enough that you won’t really get confused and think it’s black, but it’s dark enough that it’s still perfect for an office environment without any weird looks. Display and sound: The screen is clear enough and the speakers are loud
Dynabook Portégé X40L-K features a WUXGA display that’s clear enough without using too much power
Four-speaker system can pack a punch for media consumption
Dynabook has been surprisingly conservative when it comes to laptop displays. Even today some of its laptops start with resolutions of 1366 x 768 and you won’t find anything sharper than Full HD, or in this case WUXGA which is essentially the same as Full HD but with less width and height The ratio is 16:10. That’s totally fine, though, and Dynabook seems to be really focused on delivering a solid experience without overly fancy specs, which is totally respectable.
Keyboard and Touchpad: Very comfortable to type on
The keyboard on the Dynabook Portégé X40L-K feels great to type on
It has a big touchpad, but the surface is a little grippyOne of my favorite things about the Dynabook Portégé X40L-K is the keyboard. I’ve used some good laptop keyboards, and the recent Lenovo ThinkBook 13s is one of my favorites, but I think I might actually prefer this one. The travel of the keys is nice and comfortable, and they don’t feel jarring when they bottom out. It feels like it requires more power than other laptops, but I actually prefer that. Typing on this keyboard feels great, it’s definitely one of the best keyboards I’ve ever used. The power button is an odd exception, by the way – it feels soft and a bit hard to press, and I can’t remember the last time I saw anything like it. Performance: What we expect from the Intel P-SeriesThis model has an Intel Core i7-1270P processor and 16GB of RAM, so it performs very well
Intel P-series processors continue to impact Dynabook Portégé X40L-K batterylife
As you might expect from a top-tier business laptop, the performance of this machine is quite impressive. It is powered by an Intel Core i7-1270P processor, which means it has a TDP of 28W, has 12 cores and 16 threads, and the P core can boost up to 4.8GHz.
This should give you plenty of performance for a variety of work-related tasks, and having 16GB of RAM to back it up also helps, but it’s worth noting that the RAM is soldered to the motherboard, so you can’t upgrade it. I never really wished for faster performance from this machine. You can see how it compares to similar machines below. As for Dynabook laptop batterylife, it’s not great, but it could be worse. Overall, I lasted between 4 hours and 21 minutes with the screen on, giving it about 6 hours and 6 minutes. One time I only got about 3 hours and 38 minutes, but that was a deviation and I never got that low again. Dynabook Portégé X40L-K battery
life hovers around 5 hours in most cases, and often a bit longer. That’s not surprising, but it’s much better than laptops like the Lenovo ThinkBook 13s or Acer Swift 3, which have Quad HD displays. Here, the use of a Full HD panel works in the Dynabook’s favor, and you might actually consider taking this laptop with you to get some work done on the go. If it’s a full day’s work you’ll still need to plug it in, but for me the bar was set pretty low and this is still good in comparison. Should you buy the Dynabook Portégé X40L-K?
I was really surprised by a lot of what Dynabook did with the Portégé X40L-K. It’s a very nice looking laptop that’s also very light and easy to carry, it has a tall display that’s great for productivity work, and it has one of the best keyboards I’ve ever used. It even has a very loud speaker system, which I didn’t expect to be the focal point of a business laptop. Performance is solid, too, and the Dynabook Portégé X40L-K battery l
life, while not great, is more tolerable than other machines I’ve reviewed.
