I have now 2 laptops with black screen. First one is a Dell mini notebook which belongs to my granddaughter age 7. Worked perfect till we turned it on this afternoon. You can hear it booting up because sound is turned up. Ive tried the unplug and holding button for 60 seconds but doesnt work.

2nd one is acer laptop. I bought it from my gr son. screen was broken but you could still c it. I replaced the screen and also something that plugs into motherboard and screen. I can use it on a regular monitor. So for a fact its not tore up. Ive had the new screen tested and its ok . After it being hooked to external monitor is there something I have to do to go back to laptop monitor,
