1. when ever plugged in to charge via the charger can you see the battery icon with a plug sign ? - if so your charger is good. battery may be bad. If not It's opposite.
2. Are you pretty sure you installed correct way of the component after repair has done ? - check whether your cpu fan working fine. do not repeatedly turning back on after switching it off. there might be a seriouus issue. or may be a simple. but can't assume what it is.
3. If the problem still persists better replacing battery and see it sill happens. so you can come a cross strict decision that your touch up is faulty. try to fix it by yourself.
