IPC-Computer Solution-Finding - If the power supply purchase does not lead to success, our technicians will help
Customer satisfaction is our first priority - A look at our reviews or our guestbook confirms this back to the year 2004
How does the IPC-Computer "AC Adapter Finder" working?
First, when purchasing an AC Adapter, you need to find out the voltage and current values your notebook needs. A common error pattern of why the laptop is not charging after exchanging the power supply is that a AC Adapter with too little power has been selected. Luckily our AC Adapter Finder can help you find the right one. Additionally, this goes without much effort since you can easily filter out your suitable power supply with the technical data.

Tips by our workshop manager surrounding AC Adapters
Due to over 15 years of notebook repair experience, we want to help you with these 6 points in the power supplies purchase.
Defective laptop power supplies are probably one of the main issues when your laptops can no longer be turned on
If the power supply is defective, this can quickly lead to a damage on the motherboard
Tip: If the plug or the housing is defective, buy a replacement power supply as soon as possible
Our laptop technician has been advising against universal power units or replicas for years. Far too often we've had huge notebook defects in the workshop
This is why we only offer original goods, which we obtain directly from the best manufacturers
We happily share our expertise on our Notebook Doctor blog and our YouTube channel
Laptop AC Adapter FAQ
Here you can find all questions and answers surrounding AC Adapters.
This is possible, when the difference between the voltage your laptop needs and the one your charger provides is not greater than 1 Volt. So, if your laptop needs 19,5 Volt, both 19 Volt and 20 Volt chargers can be used.
Furthermore, you must make absolutely sure that the plugs of the chargers are not only physically identical, but also the pin assignment is identical, ie the pin, which is positive, it should be the same with the other charger. Be careful with chargers that have more than two pins, often a control signal is used here.
Additionally, the replacement charger should be able to provide at least the same amount of power as the old one. If it is not specified on the charger, it can be calculated from the voltage and the amperage (W = V * A).
Generally you can use a charger from any manufacturer with any device, as long as the voltage and the plug are the same and the wattage is greater or equal to that of the original power supply.
All the necessary information to calculate it can be found on the back of the power supply. To calculate the output power of the unit, use the specifications listed under "output".
Yes, you can use a power supply with a higher wattage, however you need to pay attention that the voltage doesn't deviate more than one volt from the voltage of the original power supply.
It also doesn't work the other way around; your new power supply needs to have at least the same wattage as the old one.
To use your laptop in a vehicle you need a car-adapter, which converts the 12 Volt your car provides to 19 Volt most Laptops need.
If there is no car-adapter, that is compatible to your notebook, you can use an inverter which generates mains power from the power, supplied by the car. You can then plug your normal power supply into it.
Not necessarily, try taking your battery out (if possible) and starting the computer while connected to the charger in question. If it starts, the power supply is working but something in the Notebook is broken.
There are also multiple indicator lights, on the laptop, whether it is being charged, also this can be seen in most operating systems. You can also use the indicator light found on some chargers to diagnose an issue with a cable.
Power supplies are subject to certain specifications and can reach up to 50°C. The most amount of heat is produced when working on the Notebook and charging the battery at the same time. As long as you can touch your charger without getting burnt, its temperature is probably within specification. However, it is most important, that the heat can be dissipated, therefor you should never put your power supply under a blanket or in a closed drawer.
Oftentimes the reason for this is, that with USB-C all devices have to agree on the current and voltage used for charging. Therefore, all involved devices must support USB Power Delivery, so that enough power can be transmitted to charge devices such as laptops. The cable used for charging is also part of these devices, which means you have to make sure your cable supports USB-PD. If one or more devices do not support USB-PD a maximum of 15 Watt can flow.
The middle Pin on the MagSafe 1 connector is a bit thinner, than the others, whereas on the MagSafe 2 all are the same size. In comparison to the MagSafe 2 connector less wide but a bit taller. Before the L shaped MagSafe 1 there was also a T shaped one however power supplies with it are no longer produced. The ones with the L shaped MagSafe 1 connector can be used instead.

The CE-mark confirms, that the power supply is compliant with all EU regulations.
If the CCC-certificate is present, the power supply may be im- or exported to and from China.
The NOM mark is issued by the NYCE. The NOM (Normas Oficiales Mexicanas) is mandatory in Mexico.
The PCT-certificate is mandatory for importing or exporting to or from Russia.
The PSE-test mark is mandatory in Japan and is issued by the Ministry of Economy, Trade and industry.
The Singapur Safety-Mark is issued by the technical inspection agency of singapur.
TÜV - Geprüfte Sicherheit. The technical inspection agency inspects for compliance with the product safety law, integrates many other product specific checks and asserts whether the manual is correct and complete
The UL-certification mark for sustainable products indicates, that a product has been tested by the UL Environment Inc. and is compliant with their testing criteria.
The UL Listed-mark indicates, that a representative unit has been tested by the UL and meets their safety criteria. These criteria are largely based on the safety standards published by the UL
You ordered using the part number of the power supply manufacturer (DELTA, LiteOn, …) and not the notebook manufacturers part number. The power supplies are often bought by the Notebook manufacturers and then outfitted with different plugs. These plug variants are no longer considered in the part number of the power supply manufacturer. An example: ADP-90MD H is sold by Acer with a plug with a 5,5mm outer and a 1,7mm inner diameter but other brands sell it with a 5,5/2,5mm plug.
