Guys need help over here. Leave laptop overnight, and battery went 0%. Just realise it today and quickly charge my laptop. Tried on, but no display. Black screen. Only keyboard light, mouse light and some light indicate laptop is on. Please help

Ps: tried disconnect battery and press power button up to 2 mins method. Tried to connect with TV via hdmi still nothing.

2. your mobo issues.

repairing a 5 year old laptop is not very cost effective

Just asking guys. Can a laptop be water damage when there is no water being spilled?

Are there liquid damage indicators to show that it is? (Should turn red)

Let’s do a step by step diagnostic

Assuming HDD (does not apply to SSD)
- is there a noticeable click when you power it down by pressing your power button to force shut it down? (Yes / No)

Do this first

Assuming two dimm slots with two ram modules
- remove one ram module.
- power it on, see if it works.
- if it does, then try resitting the other, and see if problem persists. If yes, it is a simple faulty ram module that’s preventing boot.
- if it doesn’t, remove and replace the ram module currently on it with the one you have removed.
