Issue encountered with Lenovo laptop performance.
Welcome to the forums, newcomer!
I own a Lenovo V15 G4 IAH laptop.
Is this the one?

Your device?
Performance drops when I connect the charger.
Could you clarify what you mean by a performance decrease?
Also, check if your laptop has any pending BIOS or OS updates.
Go to Windows Settings -> System -> Power & battery -> Power mode. Make sure "Plugged in" is selected as "Best performance". Or, if you're using a third-party power booster, verify that setting as well.
Yes, that's the model of my laptop. For instance, I often use a program named FL Studio to create music, and when I connect the charger, the CPU usage increases, leading to slower performance. This problem isn't limited to FL Studio — it impacts the whole system in general.
---------------------------
I frequently encounter feedback about gaming laptops struggling with performance.
Typically, this happens when using them while connected to a power source.
A common reason is thermal throttling.
Because laptop coolers need to be compact and lightweight, they often lack sufficient power.
If you check tools like HWMonitor or HWinfo, you’ll see the current, minimum, and maximum CPU temperatures. You can view each core individually.
For Intel processors, a maximum temperature of 100°C in red indicates throttling is occurring.
With Ryzen chips, the threshold is usually around 85°C to 90°C.
The CPU reduces its clock speed and power consumption to safeguard itself until conditions improve.
At a lower multiplier, your CPU might be operating at full capacity.
What steps can be taken?
Ensure your cooler’s airflow is unobstructed and the fan is running.
Use Windows balanced power profile instead of performance mode.
Set a minimum CPU performance level around 20%.
Although unusual, adjusting the advanced settings in Windows Balanced Power Profile to a maximum of 95% may help.
You might not immediately notice the impact on performance.
Your laptop could be entering a power-saving mode when connected. Adjust the settings in Control Panel > Power Options to choose “High Performance” or “Balanced.” Ensure the “Plugged in” option is selected under Processor power management. Set the minimum and maximum processor states to 100%. This issue has been observed with your device before.
