"Laptop does not turn on but some LEDs light"に関する回答Without proper diagnostics and tear down it is impossible to say 100% what is at fault, however one strong candidate is the battery has malfunctioned, this can also happen when they go totally flat without recharging for long periods.

Generally speaking the laptop is a relic for archaeologists to find. That being said there are some things you can try to boost the performance a little bit, but do not expect miracles and even running a browser today consumes a lot of resources as such old machines struggle a lot.

As a pro I cannot go directly to that solution without checking that everything is in perfect condition, but try it and let me know :)
