5 boots, but no chime, no display and solid white led after cleaning fan
i took my laptop apart to clean the built up dust and debris on the fan/heatsink and now when i boot the laptop, all i get is a solid white front led which stays on, but gets brighter when i close the display, no boot chime and no display. the usb ports have power as a mouse led is on, but nothing else. i have tried the pram reset but no avail. i tried the smc reset and i guess that works since the key combinations seem to work but after that, nothing. there is no response from the keyboard aka no caps light when pressed. i have taken a flashlight to the screen to see if the backlight may have quit, but when i look closely at the screen with the light, there is nothing flashing on the display. if i take the ram out, it tones with a single tone saying that there is no ram present. i switch ram out to a different slot, same thing happens as stated above.
