One of the switches would be in line with the reset pinhole on the bottom cover.

Can't find any switch there! 🙄

Do you mean not even a switch in line with the pinhole?

it is necessary to use the electrical scheme of the primary and secondary voltages.Oi! Eu não sou sou a cortana! Mas estou aqui para ajudar! Hi! I'm not the cortana! But I'm here to help!

Ok... Let me check it.0

The primary should already be matched to the AC plug type in your region.

>>>i shut down the laptop in the morning. Everything was normal. But in the evening, the laptop is completely dead.>>>OK. I think that, during this time period, the battery somehow got discharged below the critical charge level of about 5%. This can permanently damage the battery or disable its internal charge controller.So try this.(1) Reconnect the battery and put everything and the bottom cover back together.(2) Then plug the charger back in but don't try to turn it on.(3) Just leave it set for about 24hrs plugged in to see if the battery charge LED finally turns on to a steady or blinking orange.(4) If the battery LED finally does show activity, wait for it to turn steady blue before trying to turn it back on.

So this could mean that some circuit is faulty. It would be necessary to have the electrical schematic of this main board and check the voltages with a multimeter. Do you know any electronics technician?Oi! Eu não sou sou a cortana! Mas estou aqui para ajudar! Hi! I'm not the cortana! But I'm here to help!

I want to try something within my level before I hand over it to any technician. I am searching for the schematic diagram...0 -
The problem is, these electrical schematics are hard to find. You usually need to pay to download the file.Oi! Eu não sou sou a cortana! Mas estou aqui para ajudar! Hi! I'm not the cortana! But I'm here to help!

The battery could also be damaged and its internal charge controller no longer accepting a charge. Part of this controller's function is to stop charging a damaged battery that could start a battery fire. If it was mine, I would spend $30usd and try a new replacement battery instead of trying to troubleshoot and mess the mainboard charging circuits.

@JackE
Ok sir.
The battery has a 8 wire connector. Let me check any output voltage there.
I agree with your point, but the battery didn't show any decay till the PC went dead. Charging and discharging cycle was smooth as a new battery. How could it fail all of a sudden? 🤔0 -
@JackE
Completed 24 hours charging. But light doesn't turn on.
Checked the battery connecter for any output... No voltage is showing.
The laptop doesn't turn on with only AC adapter connected. (battery connector removed). Is it supposed to turn on only with adapter supply?0 -
Some do. Some don't. You can't tell anything from that.Like I said, if the battery drained below a critical charge level of about 5% during that short time period, it could be permanently even though it might've been working fine before that time period.Try a new battery before taking the mainboard apart.
