    My NP9150 will no longer run on it’s power cord. I was playing Skyrim for the first time in years. There was some terrible lag so I shut down the program. I received an alert that my battery was dying so I checked to see if the power cord had disconnected from the back. It hadn’t but I noticed it was hot. My computer shut down due to low battery and no corded power.

    I’m trying to troubleshoot if this is a computer problem or the power adapter.

    I tested the voltage of the adapter to be 19 V which is good, but I don’t know how to test the current.

    When my computer is off, the front lights indicate that the computer is plugged in and the battery is charging. When I turn the computer on the left light iturns off and the right one turns green. My computer runs fine then shuts down once the battery is spent. When that happens both lights blink orange for a while and eventually go to solid orange. This is repeatable.

    I know my battery has been unable to hold a charge for a year or two, but that shouldn’t cause this, right? My older sager runs fine without a working battery.

    Any suggestion?

    Have you tried flashing to a new BIOS/EC, I had a similar problem that was mostly fixed by flashing my EC due to it being corrupted which made my PC react really weirdly under certain temperature/power environments.

    Thank you for the reply. Is there a way to determine if the embedded controller has been corrupted or altered? I am hesitant to mess with the bios or ec before ruling out hardware issues.

    I would be hesitant to offer any tools to do so because of my limited experience. Someone like @Prema may be able to help if you could find/pm him. I noticed mine through recording symptoms and talking to people on the forums, also noticing that the fan curve on my pc was very odd and I had constant PC shutdowns due to apparent overheating despite recorded temps being well within spec.

    After charging my laptop overnight, the power light indicators were green (the left, indicating fully charged battery) and orange (the right, indicating the laptop was plugged in).

    Turning on the power the left light immediately switched off, and the right turned to green indicating the laptop was powered on. The laptop was running on battery power and the power management screen showed that it wasn't getting any corded power even though it was plugged in.

    The only applications running were Thunderbird, Mozilla, and Steam. I exited Steam to save battery power and immediately the left power light clicks back on (orange). After 10 minutes the left light changed to green (battery powered up). The computer registered that I was plugged in.

    What does this mean? Somehow some Steam prevented my laptop from running off of corded power? I turned Steam back on. Steam "updated" and my power lights are working normally and my computer is running off of corded power.

    What does this mean? What should I do now?

    Reinstall steam and see if that helps?

    It's likely the brick itself, they are a common size, is there anyone's charger you could borrow?

    Agreed, it does sound like an issue with the charger.

    So you can be sure you need a 19.5x5.5mm barrel type tip with a voltage of 19v. If all you do is want to test booting the machine a 90W brick or above should manage, just don't run a 3d load on something like that.
