I removed the battery and tried to restart. Doesnt work.

Tried battery reset button for 60 seconds. Nothing.
Left overnight nothing.
tried power button for 60 seconds. Nothing.
Removed CMOS battery. Nothing.

If I put battery back in - 2 blue lights flash on the power supply
Power is valid at the plug 19v.

Your laptop has a main power/charge rail problem that you need to get your laptop to a technician so that he can check the laptop out and check the rails out and its circuitries, as you might have a shorted mosat or a capacitor that is causing these issues with your laptop. Its not a matter if the laptop doesn't run on the adapter charger or battery, as this laptop should run on both.

This is where your problem is on your Aspire A515-44 laptop, its around the main power rail and you need a technician to check those circuitries out f any are shorted.

Your Aspire A515-44 might have a main power rail or a charging rail problem as the battery is not charging, or the battery has a problem. This problem can't be fixed with a hard reset like you have attempted, you need to take your laptop to a technician that can analyze your laptop and pinpoint where the problem is and replace appropriate mosats or capacitors. Good luck and hope this helps you out.

This is the side Power LED and Battery LED lights functions on your A5155-44 laptop:

Try a different RAM module if you have a spare one, check this video how to replace the module but make sure you are fully shut down and not using Fast Startup or are in hibernate/suspend mode. Disconnect the battery.

You can also try to short the +/- contacts inside the CMOS module after you take out the coin battery with a short electrical wire or opened paperclip; just connect the bottom terminal (-) with the side terminal (+) for a few seconds to reset BIOS.

If none of this helps bring the laptop to Acer Services in your country as it may have a hardware failure.

You also need to have your battery checked and analyzed and/or replaced as that could be a major reason why you are getting the symptoms that you are getting, have a look at this guide here "Unlock and Repairs of a battery" on how a faulty battery can affect a laptops functionality.

But a faulty battery shouldn't prevent a laptop from restarting - when the battery is removed correct ?

Hi Stepehngen
what if both power and led blue lights are blinking blue together ….. when trying to power on.

Try the procedures I posted above and if that does not work, bring the laptop to Acer Services in your country to check the ports, include the adapter.
