Lenovo Ideapad Slim 1-14AST-05 Review: Chromebook Competitor Brings MS Office 365

Slow. Lenovo's 14-inch notebook is supposed to make life difficult for Chromebooks. The device scores with a successful keyboard and a one-year MS Office 365 personal license. Computing power and memory capacity are not convincing. Just under 280 EUR are due for the Ideapad.

Case, equipment and input devices - Plastic case for the Ideapad Slim

The plastic case is a light silver grey (Platinum Grey). Alternatively, the notebook is available in the colors red (Flame Orange) and blue (Ice Blue). Processing flaws are not noticeable. The base unit and lid should have a greater stiffness. The battery is firmly installed. There is no maintenance flap. You can get to the insides by removing the base unit.

The two type A USB ports work according to the USB 3.2 Gen 1 standard. An external screen can be connected via HDMI. There is an audio combo slot on the right side of the case. The built-in MicroSD memory card reader is one of the slow representatives of its kind. The stereo speakers produce an acceptable sound that lacks bass.

The WLAN chip (Qualcomm QCA9377) supports the standards 802.11 a/b/g/n/ac. The transmission speeds determined under optimal conditions (no other WLAN devices in the immediate vicinity, short distance between notebook and server PC) turn out mediocre.

The non-illuminated chiclet keyboard is suitable for carrying out regular typing tasks. The one-year MS Office 365 personal license included in the scope of delivery fits in well with this concept. Windows 10 Home in S mode serves as the operating system. A free upgrade to a "normal" Windows 10 can be made.

Display - A TN panel for the Lenovo computer

The brightness (226.4 cd/m²) and contrast (551:1) of the matt, unstable 14-inch Full HD screen with an unstable viewing angle are too low. Compared to the notebook's price level, the values are acceptable. The display shows a flickering with a frequency of 147 Hz at brightness levels of 60 percent and below.

The color deviation is clearly above the target with a value of just under 11 (Delta-E less than 3). The display also suffers from a clear blue cast. By calibrating the screen, the color deviation drops to just under 5.5, the blue cast disappears and the gray levels are displayed in a much more balanced way. The screen cannot display the color spaces AdobeRGB (39 percent) and sRGB (62 percent).

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
14 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise
↘ 4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 17 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.5 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 24 ms rise
↘ 20 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 64 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 147 Hz ≤ 60 % brightness setting

The display backlight flickers at 147 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 60 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 147 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17878 (minimum: 5 - maximum: 2500000) Hz was measured.

Performance, emissions and battery life - The Slim 1 has weak hardware

Lenovo equips the Ideapad with a weak APU, 4 GB of RAM (hard-soldered, no memory banks) and eMMC memory. The notebook reaches its limits very quickly. Loading and starting processes are delayed. The notebook always reacts sluggishly. The device should not be expected to run more than one open application or website at a time.

The weak-breasted AMD APU is called A6-9220e (2 CPU cores, 2 threads; Radeon R4 GPU; Stoney Ridge). This slower clocked variant of the regular A6-9220 APU is passively cooled. The Cinebench R15 loop test reveals that the CPU part of the APU can only operate at high speed for a short time. The performance is already halved in the second run. The APU is on a performance level with Intel's Atom processors of past years.

The transfer rates of the eMMC module remain significantly below today's capabilities. The comparison with the eMMC memory of the Acer Aspire 1 A114-32 shows what would be feasible. Lenovo has trimmed our test device in order to be able to install the option of an M.2 SSD (see picture above). A pity. It would have given owners the opportunity to drive out some of the system's inertia. Even the cheapest SSD reacts more lively than the eMMC memory. Moreover, the memory space (about 33 GB after the initial setup) could have been expanded. All that remains is an expansion via MicroSD card.

The Slim 1 works silently, hardly warms up and is satisfied with little energy. The Lenovo computer doesn't belong to the long-runners. It ends our practical WLAN test (simulates the load when calling up websites with a script) after 5:39 h - we would have expected more here.

Verdict

The Lenovo Ideapad Slim 1-14AST-05 (81VS001VGE), provided by:

Even if the price (280 Euro) seems tempting, the possible purchase of the computer should be well considered. The notebook quickly reaches its limits and basically reacts sluggishly. There's also no way to speed up the system in any way. 

The Ideapad Slim 1-14AST-05 doesn't cut a convincing figure as a Chromebook competitor. Chromebooks generally work more agile - even models with weak hardware.

Lenovo has decided on a combination of a weak APU, 4 GB RAM and eMMC module, which is somewhat overtaxed with Windows 10. The device should only be used for one open application or website at the most. The display is from the bottom shelf - dark, low-contrast, unstable viewing angle are the keywords here. There is not much storage space available (approx. 33 GB after initial setup). Lenovo denies our test device the possibility to install an SSD. Only a memory expansion via a MicroSD card remains.

A few positive things can be said, though. Lenovo grants the Ideapad a two-year warranty. The non-illuminated chiclet keyboard has made a good impression and is also suitable for doing regular typing work. A one-year MS Office 365 personal license worth almost 70 euro is also included.

Thus, the Ideapad offers itself as an affordable typewriter for pupils and students. However, it lacks endurance. The Ideapad ends our practical WLAN test (simulates the load when calling up web pages with a script) after 5:39 h - too little for a day at school or university. Here, the power supply unit would always have to be carried along.
