Why buy Lenovo Yoga Book laptop in 2018 - merits and demerits

A wonderfully versatile and cheap 2-in-1 laptop

CPU: Intel Atom x5-Z8550 | Graphics: Intel Atom | RAM: 4GB | Screen: 10.1-inch full HD IPS touchscreen | Storage: 64GB SSD, up to 128GB microSD

The advantage of Lenovo Yoga Book:

1. Extremely thin + light
2. Excellent display
3. It's cheap!
4. Intel Atom is underpowered

If you're after a cheap laptop that offers something a bit special, look no further than the Lenovo Yoga Book. As with all Yoga devices, the screen folds flat so you can use it either as a tablet or a laptop. To add more versatility, Lenovo has now added the option to buy it with either Windows 10 or Android 6.0 onboard - which one you choose will depend how you're more likely to use the device. The screen on this thing defies the cheap asking price and the keyboard and capacitive touch-keyboard are both fantastic too. This is a great option if you want something cheap for basic computing tasks, for creating art using the built-in Wacom digitizer or a train device for watching movies. But for more heavy lifting you'd be better off choosing one of the options above as the Intel Atom CPU in this thing is great at saving power and making the battery last for ages but not so good at super speedy processing.

Some people:

Insanely thin and light

Halo Keyboard surprisingly accurate

Excellent display

Clever Create Pad

AGAINST

Woefully underpowered

Dated microUSB port

We’re immensely fortunate to live in a world where the Lenovo Yoga Book exists, and we’re not just saying that because it’s relatively inexpensive right now (but it is!). No, the Lenovo Yoga Book is worth your consideration, as it’s the unlikely combination of a tablet and a laptop in a way we’ve never seen before and may never see again.

Suffice to say, it’s a device that’s made a name for itself on TechRadar, having finagled its way onto our best laptops of 2017 list. But, why do you think that is? 

Lenovo Yoga Book at Jet for $284.99

Well, despite being convertible, the Lenovo Yoga Book doesn’t resort to a physical keyboard, at least not in the traditional sense. Instead, this laptop marks the debut of a hinged keyboard and trackpad entirely free of travel, as a result of being completely digital. That might sound weird and difficult to adjust to, but, well, it is. 

Still, it’s well worth the asking price – and, we’ll get more into that later – for offering inputs separate from the screen that you can use as a Wacom digitizer for cooking up doodles. Of course, pioneering its own, all-new category of notebook is a full-time job, we wouldn’t advise writing it off prematurely. After all, breaking new ground is bound to take some getting used to.

And finally, this is the first laptop or tablet to come in both Windows 10 and Android varieties using the exact same hardware inside.

That’s quite a lot of firsts for a 10.1-inch productivity device that costs just $499 (about £409, AU$655; Android) or $549 (about £450, AU$720; Windows 10) to start. There has to be a catch, right? 

Of course there is, but let’s focus on what makes the Yoga Book so awesome first, shall we?

Design 

The Yoga Book, at first glance, looks like every other Lenovo Yoga laptop – only smaller. The impressive, gorgeous watchband hinge first introduced with the Yoga 3 is present and correct, and the insanely thin device is wrapped in a smooth, luxurious magnesium alloy shell like so many Yoga devices before it.

The Android version of the Yoga Book, which we guess Lenovo expects to sell more of, comes in Champagne Gold, Gunmetal Gray and Carbon Black finishes. The Windows 10 version comes in just Carbon Black – though all of these finishes look downright premium.

A power button and volume rocker on the device’s right side are edged in chrome, and speakers sit behind dotted grilles on either side of the keyboard deck. The speakers pump out suitable range and volume despite their size, thanks to Dolby Atmos technology inside.

Another impressive feature about the Yoga Book despite its size is the 10.1-inch, 1,920 x 1,200 resolution screen. With 400 nits of brightness and the capability to display a range of 16.7 million colors, HD movies look excellent on the Yoga Book, and in-plane switching (IPS) means wide angles for screen sharing.

Tactile touch typing  

For those of you doubting whether an entirely digital, capacitive keyboard can cut the mustard, stop right now. In our time with both versions of the Yoga Book and its Halo Keyboard, we were surprised by just how accurate we found typing without any sort of physical buttons or feedback.

Sure, there’s haptic feedback and audio cues that signal when typing, like on a smartphone, which can be toggled on or off. But, neither completely account for how accurate we are typing on this backli

If anything, our accuracy is testament to our growing aptitude with digital keyboards since the dawn of smartphones and tablets – only this one doesn’t take up half the screen. (Lenovo’s patent-pending hardware and software helps a great deal here, too.) 

Even without auto-correct software on the Windows 10 version, we found ourselves making very few errors while working on the Yoga Book. Of course, it’s unrealistic to expect the same words-per-minute speed that you would attain on an analog keyboard, and we don’t expect everyone to have the same easy transition that we had. The Android version’s Lenovo-made TouchPal auto-correct software should help a great deal with that acclimatisation. 

This, then, brings us to a question: if all versions of Windows 10 are essentially the same operating system (OS), why then is Windows 10 Mobile’s excellent auto-correct software not available on all versions of the OS?

As for the Android version, we in fact not only found the built-in auto-correcting software to be extremely helpful, but practically essential after getting used to it being there. 

However, in order for said keyboard to work properly, we had to disable all international keyboards. Otherwise, certain key presses would register whatever the key is next to it on-screen. At least this workaround solved the issue.

At any rate, we found navigating and typing on the Yoga Book surprisingly easy after about an hour with the device. Of course, you’ll find differences between both keyboards – i.e. the Windows 10 version’s left and right mouse buttons that allow for click-and-drag and the Android version’s lack thereof – but both offer the same fidelity.

The Create Pad offers the supreme palm detection artists have come to expect from the brand, and has differing levels of support from the Yoga Book depending on the version. The Windows 10 version supports the Create Pad in all apps that would support stylus control, like Windows Ink, but specifically calls up OneNote when activated.

On Android, however, Lenovo seems to have enjoyed a lot more freedom in custom-tailoring software for the OS, with Lenovo’s home-grown Note Saver app for note-taking and drawing.

Regardless, both versions of the Yoga Book are capable of one aforementioned, seriously cool trick: taking scrawlings in pen on paper and digitizing them for later access, editing and backup. This is made possible through an included magnetic notepad that attaches itself to the Create Pad’s surface, and included (office-standard) real-ink ballpoint tips for the Real Pen.

Now, this is where the EMR comes into play. As soon as the Real Pen touches the notepad – when attached to the Create Pad surface – whatever’s written is picked up by the electromagnetic response given off by the contact of pen to paper through the notepad’s magnetic rear surface, to be translated onto the screen via the Create Pad. The accuracy with which this is achieved is incredible, and it’s something you simply have to see in action yourself to believe.

With this feature, you can even fold the tablet in the reverse direction to use it simply as a traditional paper notepad with a digital backup. Using the tablet in this way even shuts the screen off, saving precious battery life – though, the Yoga Book already has gobs of that.

But, beyond note-taking, we could see this feature being a boon for artists that feel more at home drawing on paper with ink than a glass surface with a stylus, with the option to alter their work digitally later. Of course, this assumes a lot on the front of app and file compatibility.

All told, the Yoga Book’s Create Pad and Halo Keyboard are wowing tools that separate this tablet from the majority of 2-in-1 devices. Even more so, they stand to see Lenovo spur yet another standard in dual-purpose computing devices. 

But before we get ahead of ourselves, let’s see how this thing stacks up against some of the leading tablets, and what it’s like to use as a productivity device.

How can I make sure I'm buying the right laptop charger online?

You need to consider certain things before buying the adapter/charger for your laptop.
First check the voltage and amperage. It does not matter if the amperage on the charger is higher than the amperage on the laptop. Make sure you have the right polarity by looking for a symbol on your laptop and your charger that looks like these :

 if there both the same and the voltage and amperage is good than you can charge your laptop.

Choosing a Replacement Adapter:

Find your laptop’s model number.
You may find this number located on a sticker on the bottom or side of your laptop computer. If you can’t find it there, check your user manual or search your laptop’s built-in help program for the model number. You can also find it under your laptop’s system properties.

Find your wattage requirements.
In addition to your laptop model number, you will need to find out the voltage requirements for the laptop adapter. Laptop adapters have varying voltage (V) outputs, and using the wrong laptop adapter can damage your computer. Check your user’s manual for voltage requirements information for your laptop. The output voltage will usually be listed as DC voltage. You may also want to check for product or part numbers that are compatible with your laptop model.

Find a compatible laptop adapter.
Look for the compatibility lists in descriptions of laptop adapters you are looking at. Sometimes the compatible laptop models are listed in the product description or in a separate list. Laptop model numbers can often look similar, so make sure the model numbers match exactly. Laptop adapter and power cord product descriptions typically list the manufacturer, part number and a partial description as well. If you find an adapter with the correct output voltage, but the wrong port connector, you may be able to find port attachments that will adapt the connector to the power port on your laptop.

How to Choose Batteries(Battery type)?

• The Nickel Cadmium (NiCd) battery.
• The Nickel-Metal Hydride (NiMH) battery.
• The Lead Acid battery.
• The Lithium Ion battery.
• The Lithium Polymer battery

What’s the Best Battery?

 compares the characteristics of the six most commonly used rechargeable battery systems in terms of energy density, cycle life, exercise requirements and cost. The figures are based on average ratings of commercially available batteries at the time of publication.

1. Internal resistance of a battery pack varies with cell rating, type of protection circuit and number of cells. Protection circuit of Li‑ion and Li-polymer adds about 100mΩ.
2. Cycle life is based on battery receiving regular maintenance. Failing to apply periodic full discharge cycles may reduce the cycle life by a factor of three.
3. Cycle life is based on the depth of discharge. Shallow discharges provide more cycles than deep discharges.
4. The discharge is highest immediately after charge, then tapers off. The NiCd capacity decreases 10% in the first 24h, then declines to about 10% every 30 days thereafter. Self-discharge increases with higher temperature.
5. Internal protection circuits typically consume 3% of the stored energy per month.
6. 1.25V is the open cell voltage. 1.2V is the commonly used value. There is no difference between the cells; it is simply a method of rating.
7. Capable of high current pulses.
8. Applies to discharge only; charge temperature range is more confined.
9. Maintenance may be in the form of ‘equalizing’ or ‘topping’ charge.
10. Cost of battery for commercially available portable devices.
11. Derived from the battery price divided by cycle life. Does not include the cost of electricity and chargers.

Observation: It is interesting to note that NiCd has the shortest charge time, delivers the highest load current and offers the lowest overall cost-per-cycle, but has the most demanding maintenance requirements.
