[shuvamgayen]

hello i am using a lenovo z570 laptop. Recently i am facing some issue regarding power on please read carefully
1. The laptop getting on if no AC adapter is plugged it and operating normally
2. after getting on if i plug my AC adapter it is charging my battery without any issue
3. Now in this case(AC adapter Plugged in) if i shut it down it wont power up again. even after removing the AC adapter it is not getting on. to make it work i need to open the battery and reinsert to power it on again with the battery power.
4.So what i am doing is turn the laptop on with battery then insert the adapter it is charging my battery and then before shutting it down i need to open the ac adapter. so that next time i can turn it on.


Any idea what is damaged or need to be repaired here? please give your valuable suggestion . Everything is original Battery and AC adapter
