Hello.
I received a bios locked 7410 with 25Q256JVEQ ,i dump the bios, unlocked it and flash it back, since then the laptop has no life signs at all except amber led on for as long the power button is pressed, nothing else.

Hello everyone,
I like to repair everything I can get my hands on.
A friend gave me a laptop that fell down while it was switched on.
Now the display remains dark and the laptop no longer boots up.
Since my English is not so good, I worked with a translation tool. Please excuse me if something is not translated correctly.
Normally this device is not in a price category where you have to grit your teeth, but I really want to find the error and learn something in the process
