More about volts
  1. Some of the pins are used as a logic supply voltage to determine battery charge level, temperature, etc. Most laptops won't provide a charging voltage to the battery terminals if there is no battery present. This is to prevent damage to the charging circuit by inrush current or shorts. When you say "won't boot", will the laptop turn on, post, and then hang, or will it not turn on at all?
  2. hp - 90% of there laptops contain nvidia chips

    90% of there units die after 3 years or LESS because of it

    relflow or new mobo to fix

    symptoms: power on and cuts out, power on and no display, intermittent power up issues, random shut off issues etc

    That's a kinda generic bunch of issues there. Theres's a dozen things that could cause those. I won't argue the nvidia portion of your statement, but it's not just limited to Nvidia problems.
