Laptop stops charging and blinks

Hello,
A few months after getting my Cyberpower laptop, a charging problem started. The charger would be connected, and at first, the laptop would charge, but after a few minutes, it would stop charging and the power button would blink as if the laptop were on standby. The problem stopped occurring after a week or so, so I ignored it. Now, that charger broke and I am using a different charger, and the laptop would stop charging by itself again. The charger is fine, since it works on other laptops just fine. Now, whenever I try to charge my battery, it would stop a few seconds after plugging it in, and it's just a plain hassle to disconnect and reconnect the charger so often. Please help. Any suggestions would be greatly appreciated.
Thanks.
