Aspire E14 E-5 457-53HG does not boot up . Power light is blue, battery light orange , CPU fan spins

Such a sudden, I could not start Aspire E14 E-5 457-53HG.
It is 5 years old.
Power light Blue, Battery light orange, CPU fun spins.
Both light just light up without flashing.
Its battery is dead for 2 years but it worked on AC power after that.
I used it for an hour before it happened.

I have tried
disconnect AC power,
hold down power button
reset Battery
reconnect AC
tried to turn on again .

It does not boot up to BIOS at all.
Is there any thing I can try before sending it to a repair shop?
Please advise
Thanks

Prior to this , I got only black screen when power was on, force shut down and restart again for a few times.

You must remove screws and bottom cover to disconnect the battery from the mainboard. It probably has a shorted cell. Hopefully it has not leaked inside. A dead and shorted battery is a fire hazard when connected like this.

Thanks,
I have removed Battery as you advised.
Only Blue power light is on when I switch on , CPU fun runs, LCD flash very brief and a very short sound from DVD drive as well.
They were there previously as well.
They all went off within a second but only Blue light and CPU fan remain working.
