Laptop doesn’t Boot; Power button LED is blinking

[WilliHo]

Hello guys,

I have got a problem with my notebook (HP Envy 15-1090eg, Windows 7 64-Bit). Sometimes I can boot and use it normally. But often, it doesnot boot. The display is black and nothing (like a fan or anything) starts. There is only the LED of the power button, which is blinking one time every 5 seconds (and the LED near the power cable plugin). What could it be?

I think the problem appears less often, if I plug off the power cable and the battery and just plug in the cable, when I want to start the laptop. 

Thanks in advance!

Hello,

I tried both things. With the restart after setting the BIOS to default, it shows the same problem and the laptop doesn‘ t boot.
