How to access dead phone/ repair software?

[AC Question]

Hi

My android phone does not turn on anymore.
On thursday my phone battery died, I could not turn it on anymore. I took it back home plugged it in, but the charging light did not appear. Instead I periodically hear the connection/disconnection sound. The device manager recognizes "Alcatel Single RNDIS Interface", this works with or without phone battery. If I hold down the power button I can interrupt the periodical Windows connection/disconnection sound.
I left the phone plugged in over night (so it should have charged). On friday morning I restarted my Laptop and suddenly the empty battery symbol appeared. I could use my phone and charged the battery again. I installed a battery app which did not see any problems (battery voltage is also fine). But then the phone froze, I removed the battery and I have the same problem again. The battery is charged, I can periodically hear the connected/disconnected sound but it will not turn on or show any lights.
Can I somehow send commands from my computer to update the firmware or check what is going on?
Thanks in advance!

Welcome to Android Central! Can you replace the battery? That's the first thing I'd try.
