Blinking lights and it's wont start.

Hello,

This is the first time for me here,

1 year ago I noticed that my battery lights were flashing while the charger and battery were plugged in. Before the flashing started, I could hear abip sound.

The lights that flash are:

- the power button light (blue)

- the blue light on the front

- the orange battery light

When I disconnect the charger and plug it back in, I can again hear a beep sound and the flashing disappears for a while to then start again shortly after. When these lights are flashing, the battery in windows indicates that it is not being charged.

Back then i accept the fact that I have to use the charger without the battery, or use only the battery.

But now I can't use neither of them, now my acer laptop suddenly shutdown( example : when you use the laptop using only the charger and then you inplug the charger, and it shutdown), so the problem begins to aggravate, and now when this happens i can't power it on again, when I press the power button, the blue light of the power button and the blue light in the front are blincking and noting happens, when I insist nd try this for 4 or 5 times, the laptop starts and after 2 or 3 minutes it's shutdown again.

So is the problem 1) the battery, 2) the charger, 3) my motherboard?

1) The battery

The battery is fine, i can get 2hours of usage, well.. That in the past, now the laptop is not starting using the battery.

2) The charger

I have an ASUS charger, but the same voltage and everything.

3) The motherboard, I tried the following:

1:

- Shutdown my laptop

- Disconnect battery and charger

- push power button for 20 seconds

- plug in charger and battery

- start up again

2:

I disconnect almost components( the 2 rams, the wifi card, the HDD, the screen, and the battery), but the mother board starts for a few minutes and then shut off.

Unfortunately, this did not fix the problem.

I will give you some of the pictures of the motherbord and the AC/DC and the some other pics
