Title:

MBP needs charger to wake up from sleep mode (new battery, charged)

Text:

I have a problem with waking up my MBP after leaving it for a few hours in sleep mode. It had its battery replaced 2 weeks ago and I already encountered this problem a few times. I use my MBP with or without charger, then I close the lid and put it to sleep. The battery is charged (for example 80%, 50% etc). I disconnect the charger and leave the laptop on the desk or put it to my backpack. After few hours of being in sleep mode, when I want to open it again, I get the black screen with the icon that the battery is drained and that I need to connect the charger. When I connect the charger it wakes up and the battery seems to has the same charge amount as when put to sleep. After waking up I can unplug the charger and work on battery without any further issues.

It happened just a few times with my previous battery (during more than 5 years), but after a long time of use and only while I took the laptop outdoors and it was rather cold outside. Now it is happening indoors too and almost every time after leaving laptop for a few hours.

Today I did the SMC reset but didn’t help.
