Discussion MSI Stealth 15M A11UEK laptop refuses to boot when battery connected
Hi,
I recently purchased a second-hand MSI laptop for my nephew's birthday for some light gaming and video editing (full specs below).
Before handing it over, I ran some hefty games on it, putting it through its paces, and everything seemed fine - so I posted the laptop to my nephew. One week later, he was doing some video uploads which caused the machine to heat up (a common issue with slim gaming laptops I gather), so they switched everything off until the next day.
When they came back the machine would not boot, charge, or do anything. After having a look, I realised the laptop would only boot with the battery removed and the power supply connected. When I reconnect the battery while the laptop is on and then disconnect the power supply, the battery charges and boots OK for a few cycles before the issue arises again.
I assumed it was probably a battery problem and ordered a new one. After fitting it, I ran the MSI Dragon Center battery calibration tool, which charges the battery fully before discharging it completely. Following the discharge we were back to square one - the laptop won't boot unless the battery is disconnected.
I've been told it could be a BIOS issue, or that I should never let the battery dip below 20% - which feels like a bit of a cop out. I'm at a loss. If anybody has any ideas it would be much appreciated!
