Lenovo laptop can t turn on when the power cord is unplugged, what s going on? Urgent

Your situation is indeed a battery problem. Now your battery can't be discharged, so your computer won't turn on after unplugging the power cord. 1. If your battery has not passed the shelf life (one year), in this case, you should return the battery to the dealer who sold the computer to you as soon as possible, and they will return it to the factory for repair with the computer manufacturer (free of charge).

2. The battery has been insured. Then you need to take it to the battery repair point to repair it. There are many reasons why the battery does not discharge, but as long as your battery is not broken by the battery cell, the general maintenance price does not exceed 60 yuan (of course, there are still very few repair points for repairing laptop batteries, to prevent fraud) If you don't believe in those repair points, you can check the "laptop battery manufacturer" on the Internet** or email to contact those salespeople, explain your situation and ask for their help (famous your battery purchase date and computer model), these manufacturers repair** It is also very reasonable, it will not exceed 50 yuan, but you have to pay the postage fee yourself.

Dear Lenovo users, hello! Please check whether your battery is installed correctly, and plug in the power cord for a period of time to fully charge the battery before trying to use the battery alone to turn it on. Thank you for your support of Lenovo and have a great day!
