If you loose power on your laptop that means that your laptop charger could be faulty or incompatible with your laptop ot the power socket is broken or loose.
Although there are many different laptop makes and models they all use similar chargers using different variations of connectors. It is very important to use the correct charger for your laptop to prevent physical damage, battery problems or even more serious faults.
The most important thing to remember is that you need to mach the output voltage that your laptop requires. This is written at the bottom label of the laptop itself. If it requires 15V any charger that outputs 15V or even 16V will work fine.For 19V any charger that is 19V or 20V will work fine.
The next parameter of the charger is the current it can provide. For example if you laptop requires 3.14A anything more than 2A will charge the battery fine. The current defines how quickly the charger can charge the battery. For example a 5A charger will charge a battery in 2 hours where a 3.14A will need 3 hours to complete the charge.
One more thing to remember is that the current required by your laptop should not be more than 2A than your charger can output. for example if your laptop requires 6A you shouldn't use a charger that is less than 4A.

Some Examples of the most popular high quality original chargers with their different variations of connectors and voltages
Pin Size 5.5MM x 2.5MM. Voltage: 19-20V.
These are the most popular chargers and are used on 60% of all laptop makes including some Compaq Acer and Toshiba Laptops + all Advent and Medion LaptopsPin Size 5.5MM x 1.7MM. Voltage: 19-20V.
These are used on almost all recent Acer Laptops and some Old Compaq models.
Pin Size 5.5MM x 2.5MM. Voltage: 19V.
Only the early models of HP use this type of a connector
Pin 4.8MM x 1.7MM. Voltage: 19V.
Most of the models between year 2005-2010 use this connector.
Pin Size 7.4MM x 5MM. Voltage: 19V.
Dell used this type of a charger originally and the latest HP models adopted this type.They use a unique middle pin to identify the charger and if the identifications fails it will not charge the battery.
Voltage: 20V.
Used only by the earliest models of Dell
Pin 7.4MM x 5MM. Voltage: 19V.
This charger is the most durable dell charger and it uses an extra middle pin for a charger identification. If this pin is broken or bent the laptop will not charge the battery.
Pin Size 7.4MM x 5MM. Voltage: 19V.
This is the latest Charger model of dell but unfortunately almost all chargers we have tested fail within few months.
Pin 7.9MM x 5MM Voltage: 20V.
All lenovo and most IBM use this connector. It has a middle pin but it is not used for the charger identification
Pin Size 5.5MM x 2.5MM. Voltage: 16V.
This charger is used only for the older models.
Pin 5.5MM x 3MM. Voltage: 19V.
All Samsung models use this connector type. They also use a middle pin and the charger is extremely durable.
Pin 6.5MM x 4.4MM. Voltage: 19.5V.
90% of all sony laptop use this charger connector
Pin 6.5MM x 4.4MM. Voltage: 16V.
This is the same connector type and size but different voltage. It is mainly used for smaller sized laptops and netbooks.
Pin 5.5MM x 2.5MM. Voltage: 19V.
Used by almost all toshiba chargers.
