You Must Understand This Before You Repair LCD And Power Failure Problems On Laptops

If the LCD screen turns off, it can be a failure of the mainboard or video adapter, a bad inverter or a burning neon LCD lamp. LCDs that need to be replaced usually occur because of physical cracks in the glass or blocks of dead pixels. If the CD or DVD drive does not work anymore, make sure you have tried the cleaning kit before replacing the drive and always checking the connection before discarding the old drive. Another damage is that the hard drive gets more problematic or over time the battery life decreases, but if you can’t repair the battery anymore, you definitely need to replace it with a new one.

In addition to the LCD problem, laptops can also experience power failure problems. The problem-solving process always starts with identifying what works. If the problem is related to power, (the battery is one of the reasons the laptop won’t turn on). The first step is to make sure the power is contributed to the laptop. This means checking that the LED on the battery transformer is on, and if it doesn’t (or doesn’t have an LED), make sure the ac adapter is plugged into a good electrical outlet. You can check that by unplugging the ac adapter and just plugging in a lamp or can check it with a current tester.

The next question is whether there is no status of the small LED lights on the laptop lights. With the power plugged in, even the oldest models usually have a good light power status. If you have a positive power status and the notebook won’t turn on either, the next thing you must check is the battery. Some notebook models will not operate without a battery installed either, so you must find out on the internet whether your laptop model will operate with dead or missing batteries or not.

If battery power isn’t a problem and the laptop still doesn’t turn on with good power status, it could be a problem with the power regulator, or more likely an electric power regulation (ic power component) or mainboard. Overcoming regulatory or motherboard issues requires testing equipment or spare boards to swap, and it is outside the scope of non-professionals.
