as the title says. The charger will turn off and on, along with the beeping. Another issue is the laptop will turn off after 30-45 minutes without the charger, as if the battery just gave up. Difficult to know whether its the charger or the battery itself. I did disassemble the laptop few months ago to apply thermal paste, and the laptop began to turn off without the charger. I ignored it and hoped it would go, it didn't. Just as of recently the charging issue occurred.
When i disassembled it, i did disconnect the battery and put it back in when i was done as instructed. I'm fairly sure i put the battery connector back in again properly. Here is a video of the 'blinking':
