This week, a Lenovo ThinkPad Z16 G1 (21D4/21D5) came into our Notebook-Doktor workshop with a classic symptom: battery faulty. The laptop would only run on the power adapter, and the battery would no longer charge. The customer had already replaced the battery themselves. After the replacement, the device worked for about 14 days, then the same problem occurred again.

Test report: replacement battery

It quickly became clear: Battery faulty due to a cheap replacement!

When opening it up, our technician immediately saw: the installed battery was not an original Lenovo battery, but a low-cost replacement. At first glance, such batteries often look fine, but technically there are major differences.

In the lab it became clear: the replacement battery did not provide stable voltage. One battery cell was defective – which explains why it could neither charge nor deliver power reliably. For the system, that means: the battery is no longer detected or stays at 0%.

Additional cause - liquid damage

When removing the battery, signs of corrosion on the contacts were noticeable. These indicated minor liquid damage – presumably moisture entered the device at some point. Moisture can attack the charging electronics or the cell management in the battery, which in the long term leads to a complete battery failure.

So both the original battery and the replacement battery were defective – one likely due to liquid, the other due to low-quality cells.

Repair solution – original Lenovo battery installed

After the area was carefully cleaned, our technician installed an original Lenovo battery from our stock. After installation, the device was tested multiple times: charging, discharging, and voltage stability were flawless. The ThinkPad Z16 G1 works perfectly again.

To help your battery last longer, please keep the following in mind:

  • Use original or OEM batteries.
  • Avoid moisture – even small amounts can damage the battery/charging electronics.
  • Don’t run it on mains power all the time – charge regularly.
  • If there are problems: disconnect power and have a professional check it.

Conclusion – battery faulty? Quality pays off!

A battery fault can have many causes: age, moisture, or low-quality replacements. The ThinkPad Z16 G1 case clearly shows that going for a cheap battery doesn’t pay off in the long run.

With an original Lenovo battery and professional cleaning, the device runs stable and safe again.

Here are answers to the most important questions

Typical signs are significantly reduced runtimes, charging interruptions, the device suddenly shutting down, or an indicator that stays at 0% permanently. In such cases, the battery should be tested or replaced.

Besides a battery fault, the charging electronics on the motherboard may also be affected – especially after exposure to liquid. Defective connection cables or BIOS errors are also possible causes.

Not every replacement battery is automatically bad – but many cheap products cut corners on cell quality and protection circuits. This can lead to faster capacity loss or failure. We generally recommend original or tested OEM batteries.

Yes. Moisture causes corrosion on the battery contacts and can destroy entire cells through short circuits. That’s why: if liquid gets into the device, switch it off immediately, unplug the power adapter, and have it professionally cleaned.

Depending on use and care, between 2 and 5 years. Frequent partial charge cycles, extreme temperatures, and constant use on mains power significantly shorten service life.

A customer from Schondorf brought us a Lenovo X1 ThinkPad Yoga 6th Gen (Type 20XY/20Y0) for repair. The notebook was no longer charging, even though the customer had already attempted repairs themselves. Upon closer inspection, irregularities such as missing battery screws, a bent heatsink, and improper soldering work on the motherboard were found. Such complex damage requires detailed diagnostics and professional replacement of the affected components.

The Diagnosis

Our technician, Gilbert G., found that work had already been done on the USB-C port on the motherboard. A protective component (CSD87501L) was completely missing and had been replaced by a bridge with adhesive. This component protects the rest of the electronics from overvoltage. Due to the missing protection, a soldered RAM chip (SN2001024YBGR) was damaged, rendering the motherboard irreparable. Troubleshooting was extensive and took approximately 6 hours, as all power paths and components were carefully checked.

After the motherboard replacement, the replacement date and time must, of course, be reset.
After the motherboard replacement, the replacement date and time must, of course, be reset.

Since the defective motherboard was no longer economically viable to repair, the entire board was replaced. The replacement was relatively straightforward:

Only the bottom case, fan, SSD, and some connecting cables had to be removed; the display unit could remain completely in the housing. The motherboard replacement itself took only 30 to 45 minutes (max. 0.75 hours). As part of the repair, the thermal paste was also renewed to ensure optimal heat dissipation.

The Result

After installing the new motherboard, the charging process worked perfectly again – the repair was successfully completed.

Technician's Conclusion

“The case from Schondorf once again shows how risky self-attempted soldering on modern motherboards can be. The removed overvoltage protection ultimately led to the total loss of the board here.”

– Gilbert G., IPC Technical Team –

If a notebook no longer charges, the fault is often not with the battery, but with the charging electronics or protective components on the motherboard. Amateur interventions can cause greater damage in such cases. Therefore, a professional should always perform the repair.

If your Lenovo laptop no longer starts properly or you want to access the BIOS without struggling with key combinations, you might have already noticed the small, inconspicuous dot with the arrow symbol – the so-called Novo button.
In this post, we’ll explain in plain English where this button is located, what it actually does, and when it makes sense to use it.

What is the Novo button?

The Novo button is a special key built into many Lenovo laptops (especially the IdeaPad series).
It allows you to launch specific functions directly, even before Windows has booted up – such as:

  • accessing the BIOS/UEFI setup
  • the boot menu (e.g., to boot from USB or DVD)
  • system recovery or OneKey Recovery software

In practical terms: the Novo button is your “emergency switch” if your laptop no longer boots correctly or you want to reset the system.

Where can I find the Novo button?

On most models, the button is a small, recessed button or a tiny hole with a curved arrow symbol (resembling an upside-down U). Depending on the model, it is located:

  • on the right or left side edge, often next to the power button or the power connector
  • on some devices, also directly next to the power button on the top

If you’re searching for it, a look at the user manual or the bottom of the device will help – it’s usually marked there if your model has such a button.

Tip: It’s best to use a paperclip or a thin, blunt object to press it.

How do I use the Novo button correctly?

  1. Turn off the laptop.
  2. Press the Novo button using a paperclip.
  3. The laptop won’t start normally; instead, it opens a menu with several options, e.g.:
  • “Normal Startup”
  • “BIOS Setup”
  • “Boot Menu”
  • “System Recovery”

From there, you can specifically choose what you need – such as accessing the BIOS or starting a recovery.

When should you use the Novo button?

  • When Windows no longer starts or hangs during boot
  • When you need advanced startup options like BIOS access or the boot menu
  • In the event of a system error that requires a recovery
  • If you want to fix a driver or software problem and use OneKey Recovery

You can also use it to restore a backup image or reset the laptop to its factory settings.

Important to know

  • Not every Lenovo device has this button – for example, it’s not found on most All-in-One PCs or Miix tablets.
  • In these cases, you can usually reach the recovery menu via the F2 key or corresponding Windows functions.
  • The displayed Novo menu items may vary slightly depending on the model and software version.

Conclusion:

The Novo button is a clever helper when your Lenovo laptop is acting up or you want to go directly to the BIOS. With one press of the small button, you can quickly start diagnostics, repair the system, or even completely restore the laptop – without complicated key combinations.

However, if no solution can be found despite the Novo menu or the recovery fails, our Notebook-Doktor workshop is always there for you.
We will check if there is a hardware defect and repair your Lenovo laptop professionally – quickly, transparently, and with the IPC solution promise for maximum security.
