It sounds silly, but you need to make sure the laptop is actually plugged in. This is a major reason a computer may not even start. No software tweak or hardware repair can make a disconnected laptop magically power on. The same goes for AC Adapters or Laptop Chargers. There a five main OEMs for laptop chargers and these are Delta Electronics, Chicony and HiPro, ACBel, Liteon and Flextronics. BEWARE FAKES! If the laptop powers on properly, that means the power adapter is working properly and the problem is likely a bum battery. You can always re-install the battery and try again—maybe the battery was just poorly seated.

For laptops with removable batteries, this is as simple as shutting down and disconnecting the computer, removing the battery, and then pressing the power button for five seconds. Reinsert the battery, reconnect the charger, and fire up the laptop again. For newer Macs with batteries sealed into the chassis, shut down the computer but leave the power adapter connected. With the power off, press and hold the power button while pressing Shift + Control + Option on the left-hand side of the keyboard. Release the keys and power button simultaneously, then attempt to power on the laptop.Batteries are susceptible to heat, so if your laptop is overheating, that could cause a problem. As the temperature rises, the battery sensor may misfire, telling the system that the battery is either fully charged or missing completely, causing the charging problems. You may even find that your system shuts down to prevent overheating a battery and causing a fire.

USB-C is a popular cross-platform standard for connecting peripherals, transferring data, and charging your battery. The new standard allows for thinner devices, but might also cause some confusion. Some manufacturers have opted to make certain USB-C ports data-only, so they won't charge your device. OEM stands for Original Equipment Manufacturer. Laptop brands do not manufacturer the majority of the parts that make of their laptops. CPU's are manufacturered by AMD or Intel, GPU's by Intel, Nvidia or AMD, Hard drives by Seagate and Western Digital, screens by LG and so on. Keep a spare at work or at home so your customer doesn’t ever run out of power. 2-Power adapters match or exceed original manufacturer specifications and the power connectors are constantly updated to keep pace with modern Ultrabooks.

While we generally recommend using the charger that came with the computer (or one that was made by the same company as your laptop), sometimes third-party USB-C chargers are necessary. If this is the case, try to use one that’s been certified by the USB-IF.
