To upgrade your Dell laptop hardware, first identify what component you want to upgrade (e.g. RAM, hard drive, graphics card). Then, purchase the new hardware and follow the instructions to install it. Make sure to ground yourself before touching any components to prevent static electricity damage.
If your Dell laptop would not turn on, first check to make sure that it is properly plugged in and that the power outlet is working. If that does not work, try unplugging the laptop for a few minutes and then plugging it back in. If it still would not turn on, there may be a problem with the power supply, motherboard, or other hardware component, and you may need to take it to a professional for repair.
