My laptop works fine when I connect it directly, without the battery. It also works fine if I run it off the battery alone. But if I connect my charger while the laptop is running on battery, the charger surges or shorts and stops charging (even other laptops) .... I have to unplug the adapter, wait a little bit, then turn off my computer and then plug in the charger and everything works again (battery charging and laptop working great).
Then If I disconnect the adapter and connect it again while computer is running, same thing happens and laptop stops charging ... Please help
IdeaPad y510, and original charger
PS: I tried multiple batteries, same problem.
I tried multiple chargers, same problem

Hi ayounes1316 ,
Just to verify , when you mentioned "the charger surges or shorts and stops charging (even other laptops) , would there be audible electrical noise or visible sparks even on connecting it on another laptop .
Would it be the same using a power strip / regulator since the same thing happens on a different laptop?
Update us how things go.

Thank you for your reply,
no sparks present, but I hear a tick (sounds like a relay switch sound) and the charger stops charging at that point. So when I use it on other another laptop (call it laptop B) it doesn't charge anymore.
The same Laptop B, and same charger if I unplug it from the outlet, wait a minute then plug it again to Laptop B, works again. If I unplug it again from laptop B and plug it back, no problem
Same procedure with Laptop A ( one with the problem ), I hear a click, no more charging.
My theory from what I'm noticing: When laptop A is turned on ( running on battery) and I plug my adapter, it somehow shorts or surges the adapter and turns it off .... When laptop A is turned off ( not running on battery), if I plug in adapter, no problems happen ....

Hi ayounes1316 ,
I also have the same theory in mind as even a known good laptop have the same thing.
I wonder if using a surge protector or charging on a different location would be a factor.
As this audible click may not be healthy for any electrical gadget, it would be better to stick on the practice of connecting the charger with the laptop off. Else have technical support called in for full diagnostics check.

That's what I've been doing now. I only connect when the laptop is off, and I keep it connected.
Is there a way to get the motherboard diagram of my y510p? Maybe I can isolate the problem. I took it to two computer technicians and both of them told me I need to change the motherboard, which is a significant cost to pay for a working laptop ...

Hi ayounes1316 ,
As with most OEM , detailed schematics are internal database information.
General schematics of for each model seen on the hardware manual as well as parts look up page but not specific to the systemboard although label on the pbc would still be available physically checking on it.
If the system is currently out of warranty and systemboard repair as expected is pricey , best practice as what you are doing now would be a better resolution to this behaviour . Proper inspection (on dc in port and cables) , clean up of fan and battery calibration / gauge may help after reseating it from location specially if same click would be audible even without battery.

Hi everybody, my Y300 has a strange behavior when charging, sometimes charges very quickly and others it drains the batt (without charger connected the battery discharge is ok), it happens also when charging on power off, it can be plugged 2 hours and stay in 0%, I changed the charger, changed batteries and the same behavior, sometimes it blink the led with a red light (all of this when power off). Please anybody can help me?
