Hi all,

My laptop is Acer Aspire vn7-591g. After i open my laptop to clean up dusts inside today, i cannot boot it up anymore. The power light is on, fan work and i can heard the hdd sound. but it keeps on black screen. No acer logo, even cannot enter the bios. it just powers on and keeps black screen. 

i tried to reboot it many times, but it still remains the same. i have no idea what is going on. please help me.

    OK. Probably just need to re-seat the video connectors at the LCD panel and the mainboard a few times to clean and secure the contacts. But before you do, try the Fn+F6 and Fn+F5 toggle key combos a few times with the TV still connected. The TV should go off and back on as you're toggling away. Jack E/NJ

    Try turning the display on with the Fn +F6 and Fn+F5 toggle key combos. Jack E/NJ

    Do you get the same result if you HDMI out to a TV? Jack E/NJ

    Btw before i clean up the dust, i was using my laptop working on the android studio, and opening the android simulator. And when i done my work, i didnt close it, but only press the power button once, to let it sleep. i dont know if this matter?

    Congrats. Sometimes if you don't press the double toggle key on-off hotkey combinations just right they won't seem to work. Jack E/NJ
