Batery no work Asus x542uqr

Jan 11, 2019
I have a laptop, exactly ASUS x542UQR. I bought a caddy HDD and I opened very careful to install that CADDY. I put the HDD inside . When I finished, my laptop don't start on the battery. Work very fine in the AC Power. What can I do ? m laptop isn't old . Is bought in July 2018
PS. At every start he don't start from first time. The led is on but after that instant restart and start second time and run perfect.
On battery don't want at all. If I disconnected the Ac power he shut down immediately.
