Hello,

I switch my laptop on, but there is no display on the screen. For some reason the Caps Lock light is flashing and I cannot get it to stop or anything. Also the wifi light is orange. Not sure what is wrong. It was working perfectly yesterday.

Hello Nico,

Usually, in these types of situations it is recommended to connect the laptop to an external monitor via VGA or HDMI calbe, in order to see if there would be any video signal going out from the laptop. If it does go out, then there's a need for LCD inverter replacement. If there's nothing showing either on external monitor nor display, but the fans are still working, the problem that you have may be due to the failure of the video chip. Sometimes, after much of a use and less cooling the graphics processor which is responsible for video signal transmission get unsolders, the thermic paste goes away and it gets unsoldered, therefore the screen doesn't show anything. If you possess knowledge of notebooks' hardware you can change the paste yourself by opening the laptop and check if the chipset that is next to the processor has got unsoldered or you can bring your laptop to a technician to get it soldered again.
Keep me posted on the development of the case.

Hope that it helps.
