i have a dell studio 1555 and it is 5 years old.
recently i had been working on it and it suddenly got switched off on its own.
when i tried to restart it it didn't start.
i removed the ac adapter and again plugged it in
i pressed the power button but nothing happened. i unplugged the charger and removed the battery.then i plugged in the charger.
the charging light turned up for a second and then it went off. i pressed the power button but nothing happened.
i again repeated the same activity but this time pressed the power button as soon as i plugged in the adapter(within fraction of seconds of plugging in the charger).
this time laptop got turned on without any problem
so i got to know how to switch it on,
i thought there must be a problem with the battery as it was 5 years old,
i purchased a new battery from dell store.
i installed it and tried to switch on the laptop but again it didn't turn up. then i tried to do the same trick again but nothing happened.(this time the charging light did not turn up even for a second.)
i removed the battery and did the same trick. this time laptop turned on.
i plugged in the battery when the laptop was on and it was detected and charged to 100% without any problem.
i removed the ac adapter and the laptop ran on battery for 3.5 hours.
but again when i turned off the laptop and tried to restart it(with battery still inside) nothing happened. the laptop behaved as if it is dead.
also everytime when i switch on the laptop using the trick pre boot system assessment starts.
i allow it to proceed but the laptop shuts down in the middle of that.
to use my laptop, every time i have to first remove the battery then plug in the charger and press the power button within fraction of seconds to switch it on.
the laptop works fine when it gets switched on, the battery is charged, it works on battery without the power supply and there is no other problem
this means the new battery,the charger and the laptops motherboard or any other internal circuit related to power is working properly.
also there is no beep or sign of failure.
please help!!!!!!.
