hello folks,

i just woke up from a nap and found my laptop monitor is off, tried to wake it up by clicking the keyboard and touchpad for a while but it doesn't seem to do anything, and then i decided to force restart it by pressing the power button. after restarting everything seems to be normal... but not for long.


my screen is suddenly off! i click some buttons and touchpad to wake it upf but no response, i wiggle the monitor up and down.. no response, i plug and unplug the charger.. no response, but then i noticed that the blue led indicator is on meaning the machine is on except for the monitor. then i tried to open task manager with the keyboard to see if it does anything, and i saw it! a very faint image of the task manager windows popping up on the dark screen. i turn up the brightness setting to the max and now i could see the task manager windows clearly. but now it is too bright so i naturally lowered the brightness setting, but as soon as i lowered the brightness the screen flickered and then goes dark again. after that, i had restarted the machine, reinstall and update the display driver, but it doesn't fix the issue.


tl;dr: monitor flickered then turns very dark when the brightness is less than 100%, pls help.

    (1) Press and hold power button till machine shuts off.
    (2) Unplug charger. No LEDs should be lit
    (3) Gently insert and press down on pinhole battery disconnect switch on bottom for about a minute
    (4) Plug charger back in BUT WAIT FOR BATTERY CHARGE LED TO TURN FROM STEADY ORANGE TO STEADY BLUE
    (5) Only after battery charge LED turns steady blue, turn machine back on.
