I checked the charger cable and block. I think it's fine. I tried turning the laptop on using the AC and battery. Both have the same outcome. Screen is trying to turn on then turns off. The charging/power light is blinking slow. The blinking of the light and turning on and off of screen keep on repeating with a few seconds interval. Thus, I cannot access the BIOS menu.
Then I decided to turn the laptop on without plugging the charger. Again, the light is blinking and the screen is trying to turn on the gets off. It is actually in sync with the blinking of the charging light. I let it that way for sometime. After few hours, there is a loud beeping sound.
Upon hearing the loud beeping sound, i press the power button once and the beeping disappear. I plug the charger and the charging light is on. Not blinking.
Now, since it's on charger and the charger is working fine, everytime I press the power button, you will hear the loud beeping sound. Charging/power light remains on. The screen on the other hand remains totally off. No longer turning on and off.
I hope you could figure out what is your wrong and could give me a home remedy for my laptop.
Lastly I would like to thank in advance and for you quick response to my query.
Again, thank you and God bless.
