Hello there my laptop Acer Aspire M5 serious model number Z09 will not charge, when i plug in my charger my keyboard will blink white which is normal except for the blinking and my charger will blink an orange dot every 4 to 6 minutes meaning i cannot charge. Any ideas been 4 weeks now. I had to ask myself.
You need to replace the charging cable most likely. What does it do with the battery removed and the laptop running on AC power only? Try that and see if the light on the adapter is still orange. If it's green, or at least it's normal color, and solid, and the laptop functions normally, then it's probably a dead or dying battery. If it will not power up, replace the ac charging cable.
