Reason 1: incorrect BIOS settings

On most laptop models, the error appears "Check the cable connection" due to incorrect configuration of the basic I / O system. If its parameters were changed, then incorrect values ​​could be set by mistake, for example by changing the download to the network, that is, the device as a terminal tries to connect to a remote server that does not exist.

To correct the error, it is recommended to revert the BIOS settings. This can be done using a special utility, a jumper, or a button on the device's case. We have covered the most common reset methods in a separate article.

  1. In the boot priority section, select the drive (HDD or SSD). This is usually done on the tab "Start" .
  2. In the BIOS menu, find the item related to booting over LAN; can be called "LAN boot" o "PXE boot" . Set the value to "Disabled" .
  3. Try to switch between "Inherited only" y "UEFI only" and start Windows in these modes.

You can also experiment with "Safe boot" o "CSM compatibility" disabling or enabling them.

Reason 2: HDD / SSD problems

If the laptop hard drive / SSD is not working or not connected properly, the system cannot find it at startup and switches to other boot methods (removable media or a remote server via LAN) hence the error "Check cable connection". it is produced.

First of all, you need to check if everything is ok with the connection of the hard disk (it is only relevant if the back cover is removed, new monolithic laptops are not easy to disassemble). As a general rule, the drive sits directly under the bottom cover or in a separate compartment, and access is open after removing a few screws.

If everything is connected correctly, but you still get an error when you start the system, you can try running a portable operating system to test the drive. You will need to create a Windows bootable USB stick or a «Live CD »Optical. How to do this is described in detail in our article.

Reason 3: damaged bootloader

Another reason for the error is a bootloader failure. It can be restored with Windows 10 and 7 tools, including the symbol of the system. The operating system allows automatic and manual boot record recovery, but for this you still need to create a bootable USB flash drive and start the recovery environment or console with it.
