Why the laptop does not boot beyond the manufacturer's splash screen

When you press the power button on your computer, several processes run in succession. Before the operating system boots, the BIOS, the I/O service, starts first. She, as it were, interrogates PC components, are they all working? And if any of them does not respond, then the launch fails and further processes are not possible.

Why won't my laptop boot past the manufacturer splash screen?

When the launch algorithm is clear, we can generalize and name two main reasons:

  • failure in BIOS;
  • hardware failure.

Before disassembling any device, let's try to check and fix the problem using software methods. The malfunction occurs both on a desktop PC with a system unit and on a laptop. Therefore, further we will call the devices differently, the solutions are the same.

Disable/Enable Power Button

Perhaps this is a random glitch due to power surges in the mains. Turn the laptop on and off several times, the recovery system will start.

Take the battery out of the laptop
If you have a laptop, remove the battery for 10 minutes. Insert it back.

Disconnect all external devices
USB stick, SD card, mouse, keyboard and so on. Try to turn on the PC, if it works, start connecting back one by one.

Check your boot disk

Well, if you can go into the BIOS (usually using the Del, Esc or F2 buttons), the Boot section. Here you need to see that the Windows bootloader is in the first place.

Reset bios settings

You need the phrase Restore Defaults in the Advanced Mode - Save and Exit section or Load Setup Defaults in the Exit section (there may be different paths, but the names and essence are similar).

Pay attention to the error

Error information may appear at the bottom of the screen. Copy its name and look for what it means. This will help narrow down the causes.

Disable components

If you are sure that you can figure out the device of the computer yourself and will not google every detail for what it is and how it looks like in general, then try disconnecting them one by one and trying to start (or vice versa, disconnect everything and connect one at a time).

Although search engines are sometimes very helpful even without experience.

To get started, just visually check whether all the loops are securely connected.

Next, disconnect:

  • drive (you can still open and close it first);
  • RAM (one at a time, if there are several);
  • hard drive and ideally check it on a working other computer;
  • network card;
  • video card.

It is better to change and repair components, and even more so the motherboard, in a service center.
