ASUS ROG Ally

Problem Description	Symptoms	Solution	Source
No signs of life.	- Does not charge or power on. - No fan spin. - No backlight. Conditional: - You’ve recently worked on the device yourself.	If the ambient light sensor is uncovered or defective, the console will appear to have no signs of life. This has tricked people into thinking they’ve damaged their consoles when taking off the back plate before. If you just did an SSD or RAM upgrade and are testing it without that backplate, try reinstalling the backplate or just covering the ambient light sensor with a piece of black tape or foam.
