In this article about the specifications of laptop chargers, we will look at the specifics of Lenovo.

In this line of thought, we can not fail to mention the company's latest innovation. In 2021, they introduced their new product - Lenovo Go C - a wireless charging kit.

It consists of 3 parts. A pad (pad), a power supply for the pad and a receiver that is placed under the laptop and plugged into the USB Type C port for charging. So when the computer is on the pad, it charges, and when you lift it off - it stops. You don't have to disconnect any cables.

The wireless charger is only compatible with newer laptop models - 13 or 14 inches, with a USB Type-C charging port that work with 45W - 20V/2.25A and 65W - 20V/3.25A adapters.

Those of you who have older Lenovo models will not be able to take advantage of this "extra". And those with the newer ones - note that the mere presence of a Type C jack does not mean that the charger is universal. Basically, whether you get a wireless charger or a standard (wired) one, there are some "rules" to follow. Here's what they are...

Why should we be careful when choosing a new charger?

Charging your laptop with a "whatever is out there" charger has some risks. For example - you can damage the battery, damage the charger and in the worst case "fry" the laptop's power supply.

Modern laptops have protections that minimize the risk (at least of "frying"). That is, if you use an inappropriate charger, your laptop probably won't turn on. However, our advice is not to rely on this, but to be careful what charger you charge your laptop with.

What should we consider when buying a Lenovo laptop charger?

The main indicators that will guide you when choosing a new charger are:

Input voltage

The input voltage is the current that comes from the mains supply (socket). The values are shown in volts (V), amperes (A) and hertz (Hz). 

Chargers intended for the EU commercial network must operate with an input voltage between 100 and 240V. This is the requirement of the regulatory authorities. Thanks to this requirement, your charger will be able to work almost anywhere. 

You should be careful if you buy a charger from outside the EU as it may support a different voltage. 

Voltage (V)

The voltage must EXACTLY match the needs of your laptop.

You can find information on what voltage is required on the label of your laptop's original charger, underneath the label (or on the casing) of the laptop itself, under the battery (not always) and of course, with a bit more searching, on the internet.

If you select a power supply with a lower voltage than required, the laptop may work but will not charge the battery.

If you choose an adapter with a higher voltage, there are two scenarios - first - your laptop will not start because of the protection. Second - you risk "frying" it.

Voltage is measured and displayed in volts (V) and for this reason you may also encounter it as "voltage".

The most common for Lenovo are 20V chargers.

Output current strength (A)

The output current is measured in amperes (A). You can find information about how many amps your charger runs at on the label of the original charger or on the underside of the laptop case. The values are listed immediately after the voltage.

The output current strength should be greater than or equal to that required by your laptop. The adapter will load less during operation if the power is greater, which is a prerequisite for longer operation. In case you use a weaker adapter, it will have to compensate and the chance of it breaking down faster is greater.

Power (W)

Power is not always indicated on the charger label. In cases where it is, it is located independently at the top or bottom of the label. It is measured in watts (W).

If the power is not marked anywhere, you can calculate it by multiplying the voltage by the output current. For example, if you have a charger with a voltage of 20V, and an output current of 3.25 A, this means that the power of the adapter is 65 W (20x3.25 = 65). In case you need a more powerful charger and choose one with a higher amperage - for example 4.5A, then the power of your charger will become 90W (20x4.5 = 90).

Type of plug

The size of the socket must perfectly match the socket of the laptop. Otherwise you risk damaging the inlet.

Some chargers are compatible with different laptop brands because they use the same plugs. But note that not all are.

Lenovo use jacks with three pins (+; 0 and center pin), similar to Dell and HP.

The most common jacks are:

  • 4.0 x 1.7

  • 5.5 x 2.5 

  • 7.8 x 5.5

  • Square

  • Type C

What is the easiest way to find the right charger?

You can find your charger by searching for it by product number or simply by using the search filters on the site.

What are the most common problems and how to make sure that the laptop charger does not work?

1.The charger is plugged in, but the laptop doesn't work. Most common reasons:

  1. Defective adapter
  2. Broken cable
  3. Another non-power problem
  4. Improper adapter (you took your colleague's charger in speed)

Usually, when the problem is with the charger or the cable, none of the lights on the laptop are lit.

2. The charger is plugged in and the laptop works but does not charge the computer battery. Most common reasons:

  1. Problem with the battery
  2. Interrupted third pin of the charger socket
  3. Improper adapter (you took your colleague's charger in speed)

To make sure the problem is with the charger or the battery, it's easiest to test with another charger or test the battery on another laptop.

3. The charger works and charges the battery, but makes a loud buzzing sound.

You can continue to use the charger, but be more careful. Do not leave it on when you are not around the computer. A sign that there is a higher chance that you will soon have to buy a new one.

4. The charger works and charges the battery, but it heats up too much.

It is normal for the adapters to heat up during prolonged operation. It is difficult to determine when the heating is within normal limits, but certainly, if you can not keep your hand on the surface of the adapter when touching, it is good to contact a service center or directly consider replacing it with a new one.

5. The laptop turns off when moving / moving

Most often the reason for this is in a broken / damaged socket on the laptop itself

6. The laptop turns off for no apparent reason when running on charger

The most common cause of this problem is a broken / damaged socket on the computer itself
