Try a power refresh in case a corrupted BIOS is the cause of the problem.
Disconnect the charger from the laptop (if connected) and then remove the main battery from the laptop.
''Press and hold the laptop's power on button for a full 30 seconds and then release it.''
Reinsert the main battery, reconnect the charger and try turning it on¹.
If it still won't turn on you may have to try a full power refresh. This involves removing the RTC coin cell battery from the motherboard. This battery maintains the BIOS settings when the laptop is turned off. It is a non rechargeable 3V Lithium coin cell battery that usually lasts for ~5 years. When this battery's voltage drops then there's a chance that the BIOS can become corrupted preventing the laptop from starting normally.
Unfortunately for you, this battery is mounted on the underside of the motherboard, so the laptop will have to be nearly completely disassembled to get to it.
Below is an image taken from this teardown [link|https://www.youtube.com/watch?v=YN7X5WXNRVM|video] showing the location of the battery on the board.
Once the battery is out, measure its voltage. If it is <2.4V DC or >5 years old replace it. Remember to reinsert the battery the correct way i.e. +ve on top as marked on the battery. Usually the battery type number is stamped on the battery. If looks like it is a CR2032. If this is the case then these are commonly available most everywhere, e.g. supermarkets.
Reinsert the RTC coin cell battery, reassemble the laptop, reinsert the main battery, connect the charger and check if it now turns on OK¹
¹ If it turns on OK there ''may'' be a message stating that the date and time are incorrect. This is normal as the BIOS has been reset back to its factory default state. Once the date and time have been corrected the message won't appear the next time that the laptop is started. Also any user definable BIOS settings that were changed by you to suit whatever operating requirements you wanted, will have to be changed back again as well.
