HP Pavilion 15-ac600 original AC-adapter 45.0 Watt normal

It's very easy - in just a few steps:

1. Enter your laptop model:
   Enter the exact model of your laptop in the search field at the top of the IPC Computer website (e.g.Lenovo ThinkPad T14 or HP ProBook 450 G7).
2. Select the AC adapter product group:
   In the results list, you will find the AC adapters directly after the batteries.
3. Compare performance:
   If your model is offered with several AC adapters (e.g. 65 W or 90 W), take the AC adapter that has the same output as your previous AC adapter.
   - This output is usually written on the old AC adapter in the "Output" line (e.g. 19.5 V - 3.34 A = 65 W).
4. No more old AC adapter?
   No problem: Look on the bottom of your laptop for the entry "DC Rating"or "Input " - there you will find the voltage (V) and current (A). These values give you the required power (V × A = W).
5. Select original:
   In our store, you will only be shown original AC adapters that are an exact technical match for your model. This means you are on the safe side when it comes to performance and compatibility.

Tip: If you are unsure, you can also send the name of your device or photos of the rating plate of the old AC adapter to our service team - we will help you find the right AC adapter free of charge.

If your laptop battery no longer charges, this can have various causes. Often the problem is not with the battery itself, but with the AC adapter, the charging electronics or the software settings.

Possible reasons:

• The AC adapter or cable is defective or not connected correctly.
• Contacts or plug connections are loose or dirty.
• An outdated BIOS or faulty drivers are impairing the charging function.
• The battery is actually defective and should be replaced.
• The charging electronics in the laptop are defective.
• A battery protection mode is active in Windows or in the BIOS that limits charging.
• The power socket is defective and often has a loose contact when the plug is moved, or it is located unusually deep in the device.

If your laptop does not charge via USB-C, this is usually not due to a defect, but to compatibility or performance problems. USB-C uses the power delivery standard (USB-PD), which must be supported by both devices.

The most common causes:

• Too little power: For example, your AC adapter only delivers 45 W, but your laptop requires 65 W or more.
• Unsupported protocol: The AC adapter or laptop do not speak the same USB PD standard.
• Poor or defective USB-C cable: Not every cable transmits the required power - especially with fast charging functions.
• Dirty or damaged USB-C port: Dust or scratches in the port prevent a stable connection.
• Firmware or BIOS settings: Some manufacturers disable USB-C charging in the BIOS or limit it in case of overheating.

Troubleshooting tips:

1. AC adapter check: Always use a USB-C AC adapter with sufficient power and USB-PD certification.
2. Cable test: If problems occur, test another certified cable.
3. System reset: If the laptop is still not charging with the original USB-C power adapter, a BIOS update or a brief power reset (disconnect the battery and power adapter, press and hold the power button for 30 seconds) will often help.

Caution: You can tell that charging is working if the charging indicator reacts immediately and the AC adapter clicks or hums briefly. If this does not happen, there is almost always a compatibility problem.

This depends on how wrong the charger is - but the basic rule is: a wrong power supply can seriously damage your laptop.

Possible consequences:

• Insufficient power (watts): The laptop only charges very slowly or not at all, switches off under load or, in the worst case, the AC adapter overheats.
• Voltage (volts) too high or too low:Electronic damage to the mainboard or battery may occur - in some cases immediately, in others only after some time.
• Incorrect plug or polarity: The device receives no power or short circuits occur or the power socket is damaged (e.g. PIN breaks).
• Non-certified replica power supplies: They often supply inaccurate voltages, use inferior components and can therefore overheat, melt or even cause fires.

With USB-C devices with the Power Delivery standard, the risk is lower as the laptop and charger automatically negotiate how much voltage is allowed to flow. A non-compatible AC adapter will usually simply not charge - the only danger here is with cheap replicas without PD certification.

Conclusion:
The wrong charger can lead to anything from harmless charging errors to permanent device damage. For maximum safety and a long service life of your laptop, you should always use an original AC adapter for your laptop. The easiest way to find this is to search for the laptop model in the IPC Shop.

Inside a AC adapter are components that convert the mains voltage (e.g. 230 V) into the right voltage for your laptop. GaN AC adapters use gallium nitride semiconductors for this purpose.

This has several advantages:

1. Smaller & lighter
   • For the same output power (e.g. 65 W, 100 W or 240 W), a GaN AC adapter can be built much more compactly.
   • Ideal for on the go, in the home office or if you have little space in your bag.
2. Higher efficiency, less waste heat
   • GaN components work more efficiently, so less energy is lost in heat.
   • Although the AC adapter does get warm under load, it generally runs more smoothly and can be more durable.
3. High performance in a small space
   • Very powerful AC adapters (e.g. 100 W, 240 W) are also possible with GaN in a relatively small form factor .
   • This is exciting if you want to operate a powerful laptop, a docking station or several devices with one AC adapter.

Important: GaN AC adapters are currently still somewhat more expensive than conventional laptop AC adapters. The combination of compact form factor and proven quality makes them an attractive choice for many customers.

For many laptop models, several suitable AC adapters are displayed in the store. This is normal and has technical reasons, but can quickly lead to uncertainty ("Which one is the right one?").

Basically, all AC adapters displayed for your device are compatible, but differ in terms of

• Output (watts): e.g. 45 W, 65 W, 90 W, 120 W, 180 W ...
• Connection type: classic round plug, proprietary plug, USB-C etc.
• Design & technology: compact, flat, GaN technology

What is GaN?
GaN stands for gallium nitride -a modern semiconductor material. GaN AC adapters can be

• besignificantly smaller and lighter
• often work more efficiently (less heat loss)
• are therefore ideal for traveling or if you simply want a more compact AC adapter

Technically, they fully replace classic power supplies. The only important thing is that the power (watts) and connection type match your laptop.

How to choose the right AC adapter

1. pay attention to the power (watts)

• Check your old AC adapter: Look for the power rating in watts (W)
• If only volts (V) and amps (A) are specified, you can calculate it:

Volt × Ampere = Watt

Recommendation:

• A power supply with the same wattage is a safe 1:1 replacement
• You should avoid using a power supply with less watts than your original - the device may become unstable or the battery may only charge very slowly.

2. round plug or USB-C / Power Delivery (PD)?

In the past, most laptops were only supplied with a classic round plug power supply. Today, many models also support charging via USB-C with Power Delivery (PD) - even if a round plug power supply was included in the original scope of delivery.

This means for you:

• If your laptop has a USB-C port with charging/PD support, you can in many cases
  charge it with a suitable USB-C power adapter, even if a round plug power adapter was originally included.
• Prerequisite:
  • the USB-C port on your laptop supports charging/PD
  • the USB-C power supply provides enough watts (at least as much as your original power supply or as recommended by the manufacturer)

Advantages of USB-C / PD AC adapters:

• Often more universally applicable (laptop, tablet, smartphone, docking station)
• Usually more compact and lighter in combination with GaN technology
• Ideal for traveling or mobile working

If you don't feel like experimenting, simply stick with the plug type of your current power supply (e.g. classic round plug). If you want to be more modern and flexible, you can consciously switch to a USB-C PD power supply - provided your device supports USB-C charging.

Modern laptop AC adapters are so-called switching AC adapters - they work with very high switching frequencies and should function practically silently. If you still hear a humming, hissing or whirring noise, this is not normal and often indicates a technical defect or inferior components.

Typical causes are

• loose or poorly potted coils and capacitors,
• incorrect switching frequency or inadequate filtering,
• component wear or voltage problems in the mains supply.

Such noises hardly ever occur with original AC adapters as they undergo strict quality and safety tests. Replica AC adapters, on the other hand, often use simple components without sufficient interference suppression - here, humming or hissing is a clear warning sign.

Important: If an AC adapter hums or hisses audibly, stop using it!

Disconnect it from the AC adapter immediately and dispose of replica AC adapters immediately, as they can pose a safety risk. Only use original AC adapters to ensure a stable, quiet and safe power supply for your laptop.

Many years of experience in laptop repair clearly show that you should use original AC adapters or tested branded AC adapters wherever possible and not cheap replicas because:

• Safety:
  High-quality AC adapters have tested protective circuits and deliver a stable voltage. Cheap replicas often cut corners here - in the worst case, this can damage the electronics or the battery.
• Compatibility:
  Original AC adapters are precisely matched to your device (voltage, power, plug, recognition by the lapptop). With "any" replicas, problems such as "AC adapter is not recognized", "does not charge properly" or performance drops under load occur more frequently.
• Reliability:
  A good AC adapter should simply work inconspicuously. Original or OEM AC adapters are generally more durable and fail-safe than very cheap no-name products, which often lack quality and final inspection.
• Cost-effectiveness:
  The surcharge for an original AC adapter is significantly lower than the costs for a possible repair of the mainboard, charging electronics or battery. You also save yourself the hassle of returns and incorrect purchases.

The bottom line is that an original or OEM AC adapter is often a little more expensive, but you get maximum safety, full compatibility and less risk - and that is precisely what is crucial for a safety-relevant component such as the AC adapter.

No, just because the AC adapter has more watts, your battery will not automatically charge faster. The decisive factor is the power required by your laptop and the permissible power of the charging electronics - not the maximum power of the AC adapter.

How does charging work technically?

• Every laptop has built-in charging electronics that regulate exactly
  • how much current flows into the battery and
  • how quickly or gently the battery is charged.
• The AC adapter only provides the maximum possible power - it does not "force" this power into the laptop.
• Your laptop only "takes" as much power as it is designed for.

This means:
If your laptop is only designed for 65 W, for example, a 90 W or 120 W AC adapter alone will not provide a turbo charging. The device limits the charging current itself.
