Compaq evo n610c has battery charge light (orange) flashing 8 times and will not power up

Charger faulty or Motherboard problem.
You can check the power supply of the charger by measuring the DC voltage at the DC jack with a multimeter set to DC volts (red probe on the inner of the jack, black probe on the outer of the jack, should measure 18-20 volts.

Also check the security of the jack in the DC port, make sure it is not loose

See if the Ac adaptor has a green led on it, flashing LED indicates power not being "used " by the laptop

Gut instinct with this being a compaq is that the fault lies in the motherboard

don't waste money on buying second or used.
buy original from near HP store or order online. check HP center near

Remove your battery - start the unit on A/C then after booting up refitted battery.

My compaq evo n610c have the following problem: "103 circuit charge failure" and use power AC only.
