The Lenovo Ideapad 100 is worth it

The low price does not have a negative effect on the design: The Ideapad 100 weighs less than two kilograms and, with a height of 2.3 centimeters, is relatively slim for a 15-inch notebook.


The Ideapad 100 is only recommended under certain conditions: You are looking for a notebook exclusively for surfing and for simple office tasks. And you don't want to spend more than 300 euros. Then you have to make do with weak computing power and the mediocre battery life. The screen quality is also not convincing - but this is no different with many notebooks that cost 100 euros or more.

However, with a 400 euro notebook like the Acer Aspire 15E you get a more workable speed and more features.


Light weight

Very quiet in operation

Decent keyboard


Weak battery life

Moderate computing power


It is only at the pace that you notice where Lenovo has saved. The IdeaPad works with the Pentium N3540 processor. The quad-core comes from the Bay Trail family, which is actually intended for tablets. Therefore, it doesn't really get the notebook going despite the standard clock rate of 2.16 GHz (maximum 2.66 GHz in turbo mode). It clearly lags behind notebooks with a Core i3, which, like the Acer Aspire E15, are around 100 euros more expensive. This is already noticeable when surfing or working in the office. When using multimedia, the IdeaPad even needs two to three times as long as a notebook with a Core i3 for image processing and format conversion.

The low computing power is also noticeable outside of the test benchmarks: Waiting pauses are not uncommon - for example, until Windows displays results after an entry in the search line or lists the installed apps. The speed deficit in the gaming performance becomes even clearer: Most games do not even run nearly smoothly. Even with games that are three years or older, you have to lower the resolution and are only allowed to set minimal graphic details.


The IdeaPad 100 only offers a minimum of other components: the hard drive only has a capacity of 500 GB, the slow WLAN only transmits with an antenna and only via the 2.4 GHz frequency, which is prone to interference. At least the notebook comes with a DVD burner and a LAN connection with gigabit speed. All connections are on the left side of the case: Below are two USB ports, of which only one delivers 3.0 speed. After all: the SD card reader is connected internally via PCI Express so that it can also work with fast cards.

A special feature of the IdeaPad is the so-called Novo button on the left front of the case: With this you can access the BIOS setup or trigger the OneKey recovery from Lenovo to restore the factory state or a previously saved state if Windows no longer starts.


The screen has a resolution of 1366 x 768 pixels: The point density is therefore a moderate 100 ppi, the image looks blurred and letters have visible steps. Since the brightness of 212 cd / m2 is not particularly high, reflections of the ambient light on the reflective display surface are often annoying. Also annoying in everyday life: the stable viewing angle is very narrow. If you do not always sit quietly in front of the notebook, the changed plan view immediately changes the brightness, contrast and color representation: Photos and films are therefore not much fun on the Ideapad 100.

Battery life

You hardly benefit from the low weight of the IdeaPad: In the battery test when surfing via WLAN, the notebook gives up after 2.5 hours - it is therefore unsuitable for on the go. No wonder - the battery in the IdeaPad is only half the size of most notebooks with 24 watt hours.


Typing on the Ideapad 100 is comfortable: This means that you can also write longer texts without your hands getting tired. The keys don't rattle or bounce, the keyboard is built in stably. Whether the travel is too short and the pressure point too soft can be a matter of taste.

On the other hand, there is nothing to discuss about the poor quality of the touchpad: The mouse pointer can hardly be positioned exactly with it, and it usually reacts to inputs with a minimal delay. The button bar below the touch field is installed at an angle: on the left it does not always trigger a click when you press, on the other hand you have to touch the button with enthusiasm for something to happen. An external mouse is therefore definitely the more convenient control method with the Ideapad 100.
