Laptop keyboard replacement manufacturer and supplier in China? Laptop computer keys come in all shapes and sizes. Although the basic layout of the keyboard remains homogeneous, some keys (like the function keys, delete, enter and space bar) may be in different positions or have different markings on them. The little plastic clips that hold the key to the keyboard base will vary in size as well. Typically, there are three basic sizes for each keyboard: the small, rectangular keys like the f1 – f12, all the square shaped letter/number keys (A-Z, 0-9) and the large keys (tab, caps, enter…). The fact is that no matter the size and shape of the plastic retainer clip, they are all very similar and relatively easy to replace and the repair process is not unique.

I said in the beginning that there were a few caveats. The Voltage needs to be the same or at least very close to that required by the laptop. We would generally not recommend using a charger or more or less than 1V of what is required by the laptop. HP have 18.5V, 19V and 19.5V laptops and we’ve never had a problem with supplying either of these charger for any HP laptop. Fujitsu laptops generally require 20V, but we’ve never had a problem with 19V chargers. You can not however use a 15V charger on a laptop that requires 19V or vice versa. The Polarity must match. Barrel connectors usually have the negative on the outer sheath and the positive inside the inner hole and to be honest we have never come across a laptop charger which is different.
Watts are a measurement of total power consumption – a combination of volts and amps. If voltage is the width of the river and amperage is its speed, wattage is the total volume of water. To find wattage, you simply multiply the voltage and amperage. So if you’re using a 5.0-volt, 1.5-amp USB charger, you’re getting 5.0V x 1.5A = 7.5W of power. Similarly, you can find the amperage by dividing the wattage by the voltage. So a 100-watt, 5-volt charger supplies 100W ÷ 5V = 20A of power. This calculation can be useful, since chargers will often list wattage or amperage, but not both. You can also divide wattage by amperage to find voltage, if need be. But you’ll rarely, if ever have to do this, since almost all chargers will prominently list their voltage.

There are no guarantees on quality. Many of the universal chargers we looked at on eBay and Amazon came with no mention at all on warranty either. By nature of a universal charger, many of its parts are removable (such as the pin section). These can be wobbly or poorly fitting and will degrade over time. Finally, many universal laptop chargers have a switch to manually select the required voltage. Plugging the charger into your laptop with the wrong voltage selected can cause irreversible damage to your laptop. In summary for universal laptop power adaptors, we can’t recommend them as there are too many factors that can risk causing damage to your laptop.
Find your laptops wattage: When using our site, this isn’t essential as we list replacement power supplies based on their precise model number, and they’re guaranteed to work for your device. However, it’s always good practice to understand the power requirements for your laptop. The main element you’ll want to look for is the output voltage for the charger (sometimes referred to as DC voltage). Check in your laptop manual for the voltage requirements or look at the original power supply if you still have it. It will often be something like this: OUTPUT: 19VDC 3.42A By multiplying the output voltage and amps you can calculate the total wattage of your machine, in this case 65W after rounding up.
