I have problem with my laptop. I have a laptop with built in battery. An acer aspire e15. My problem is when i am playing games it becomes now lag or delay. And when i plugged in to the socket/when i put it on charging it works well. I dont know why it becomes delay or lag if it is not plugged in even it has a battery. someone help me. I am affraid. Hoping to works well. I am always playing games while it is plugged in. But if it is 100-90% i remove the plug and then put again while playing until it fully charge. Please help me sir. Thankyou
