To protect your battery pack from being overcharged, your laptop will not begin charging until your battery has less than 95% of its capacity. Attempt charging the laptop only when the Power Meter shows less than 95%.

Outdated Drivers ¶ 

Outdated drivers can cause your charging port to malfunction. Windows will update your drivers automatically, unless windows updates are not turned on.

Lack of Thermal Paste ¶ 

Thermal paste maintains a point of contact between the CPU and its heat sink to facilitate heat dissipation. Thermal paste may degrade over time, or spread away from the center due to heatsink dislodging or bumping causing your CPU to overheat. To fix this, clean off any thermal paste residue off of the CPU, then apply a fresh layer to the center of the CPU. Push the heat sink back into place and tighten the screws.
