its ok if with surge protector UPS

working on laptop with charger connected is actually not good. as what happened to you. people say to detach battery because replacing battery is expensive.

safest way for your laptop and yourself is to work on battery and only charge when low on batt.

I reckon detach the battery is easier as I may forgot to detach the battery after fully  charged....haha..

Lesson learned ... Hopefully is only the charging port having problem

nope. continuous charging isnt good for laptop. heats it up. damage the mobo or processor faster. ive 1st gen i5 still working like new. just replaced new battery and body.

sorry, first time heard this theory

i read the technical tips 15years ago in i.t website. i didnt make it up.infact, you can test yourself.

Lithium aa battery era

maybe he never heard FET - integrated switching-mode battery charger with power path management and On-The-Go controller for single-cell Li-Ion and Li-polymer

i was charging my laptop 24 hour x 7 for over 2 year without off ( with UPS), so far ok

Guys.  I need your help.

I was working on my laptop yesterday and suddenly there was a loud lightning as was raining heavily.  Next thing I know was a fuse triped in my house and my laptop was turned off as I did not attach the battery. 

I found out  that my ac adaptor is not working later as the led light is off .  I can power up my laptop using battery. 

I use another ac adaptor but it will not charge my laptop and battery and  I can't turn on the laptop without using the battery.

Do you think the lightning burned the charging port of my motherboard? Or anyone have experience in this?

Thank you very much
