▶ Keyboard

mouse B5-R5 keyboard

▲ Tap or click to enlarge

The keystroke (distance where the key sinks) is about 1.8 mm, and the feeling of keystroke is solid.

The beginning of typing is a little hard typing feeling.

3 rows of numeric keypadIt’s a shame, but it may be better than no numeric keypad (depending on your taste).

Right side of keyboard

* Recently, as the border of the display has become thinner, the width of notebook computers has become more compact, so the number of notebook computers with three-row numeric keypad is increasing even for 15.6 inches.

It’s a pity that the cursor keys (arrow keys) are small, but by holding down the Shift key, you can also use the numeric keypad to operate instead of the cursor keys.

For the function keys (F key), Windows default functions such as full-width katakana conversion are prioritized.

F key

(To use the unique functions assigned to the F key, such as raising and lowering the volume, press the Fn key at the same time.)

The key top (the surface of the key) is almost flat.

Key top up image

The typing sound of the keyboard is a little quiet.

The keyboard backlight is not installed.

Key pitch etc.

Comparison with desktop PC keyboard

▲ Comparison with desktop PC keyboard

▼ A key pitch (key-to-key spacing) of about 19 mm, which is said to be easy to type, is secured.

Key pitch

▼ Since it is a 15.6-inch notebook PC, the palm rest is large enough.

Place your hand on the palm rest


The clicking sound when you press the touchpad is rather loud.


In addition, it should be notedIt is convenient because you can switch the touchpad disabled / enabled with the Fn + F1 keys.

▶ Speaker

Equipped with a speaker on the bottom.

Mouse computer mouse B5-R5 speaker

I felt that the sound quality of the speakers was “I want a little more sound omission.”

I think the sound quality is high enough to enjoy music while working.

▶ Display

It looks a little dark when viewed at an angle.

However, it doesn’t look faint, so I could use it without feeling any difficulty when using it alone.

▼ I tried to open the display. You can even open the display 180 degrees and lay it flat in this way.

Since it is a non-glare liquid crystal, it is difficult to be reflected.

The display of the mouse computer mouse B5-R5 isSince it is a non-glare (non-glossy) liquid crystal, it is difficult to reflect.

▶ Battery life

■ Actual measurement of battery drive time

JEITA Ver.2.0 About 8 hours 30 minutes
* Manufacturer announced value
Used for browsing the internet and typing text
(Load: Light)
6 hours 45 minutes
(Load: Medium)
4 hours 56 minutes
* Time until the battery level drops below 20%
Amount of battery that could be charged in 30 minutes About 41%

* Control Center 3.0 performance settings are measured in “Entertainment”.
* Display brightness: Measured at 80%. The darker the display, the longer the battery life.

Tap (click) here to see the measurement conditions, etc.

■ Battery drive time measurement conditions for “used for browsing the Internet and typing text”

  • Display brightness:80%
  • Battery saving function: Turns on with 20% or less battery remaining
  • Web browsing: Open 5 tabs in your web browser and display the website in each tab. Each of those tabs is automatically reloaded every minute.
  • typing: Using software called BBench, typing input is automatically performed every 10 seconds.
  • In the above state, measure from 100% battery level.

■ About “PCMark 8 WORK”

It is a measurement test of the battery drive time with the software “PCMark 8”.
It also includes operational tests that have a significant impact on battery life, such as viewing 3D images on websites and video chatting.

The larger the display size, the easier it is to drain the battery.

With a large 15.6-inch display, this battery life is not bad.


I tried to see how noisy it would be when it was loaded.

Measured from a distance of 30 cm in height and 30 cm in depth from the hinge, taking into consideration the position of the ears during use.

In addition, the setting of Cotrol Center 3.0 is set to “Performance” for measurement.

When idle Almost silent
* You can hardly hear the operation sound even if you bring your ears closer.
Benchmark test Around 43db

Even if the fans are full and do their best, it doesn’t make a very loud noise.

You can use it in a quiet place such as a library without worrying about your surroundings.

* However, when the fan speed setting is set to the maximum, a fan sound of around 57.5db is heard, so there is a possibility that the sound will be louder than the above.

Fan speed setting

▲ Fan speed setting

■ Estimated noise (number of decibels)
