Frequently Asked Questions & Solutions

AC Adapter – Frequently Asked Questions

What are the output specifications of this adapter?

Wattage: 135W | Voltage/Current: 20V 6.75A | Connector: USB-C

These specifications must match your laptop's original adapter to ensure safe and stable power delivery. Using an adapter with incorrect voltage or current can damage your device or cause it to malfunction.

Which laptop models is this adapter compatible with?

This adapter is designed for laptops that require 135W and use a USB-C connector. It is compatible with models listed in our product description. Please check the part number (Yoga Slim 7 Pro-14ACH5) against your original adapter – if they match or are listed as compatible, it will work.

Important: Even if the connector fits, the voltage must match exactly (e.g., 19V vs 20V). Using a different voltage can permanently damage the motherboard.

What connector type does this adapter have, and how do I check polarity?

This adapter uses a USB-C connector. Common types include:

Barrel (round) connectors – have inner and outer diameters (e.g., 5.5mm x 2.5mm). The centre pin is usually positive (+), and the outer barrel is negative (-), but some brands reverse this.
USB Type-C – the standardised connector for modern laptops; polarity is managed internally and is not user‑adjustable.

Always verify the polarity of your original adapter before connecting. If the polarity is reversed, the laptop will not power on, and the protection circuit may be triggered (or in worst case, damage the system board).

What should I pay attention to when using this AC adapter?

Input voltage range: Most adapters accept 100‑240V AC, 50/60 Hz – check the label for your region.
Heat dissipation: Place the adapter on a hard, well‑ventilated surface; do not cover it with cloth or paper.
Cable management: Avoid bending the DC output cord sharply near the connector – this can break internal wires.
Physical damage: Inspect the plug and cable for cracks or exposed wires before each use.

What if the laptop does not charge or power on with this adapter?

Check connection: Ensure the plug is fully inserted into the laptop and the wall outlet.
Check LED indicator: Most adapters have an LED – if it is off, the wall outlet may be faulty.
Verify specifications: Compare the output voltage and current with your original adapter – they must be identical.
Test with another device: If possible, try the adapter on a compatible laptop to isolate the issue.
Reset the laptop: Unplug the adapter, remove the battery (if removable), hold the power button for 15 seconds, reconnect and try again.

If none of the above works, the adapter may be incompatible or defective – contact our support for assistance.

Quick Tip

Always use the original adapter or a certified replacement. An undersized adapter (lower wattage) may cause the laptop to throttle performance or fail to charge while under load. Over‑sized adapters (higher wattage) are generally safe, as the laptop draws only the current it needs – but voltage must still match exactly.
