Laptop has no power and wont charge

I have a Lenovo Yoga 710-14IKB. It went dead and now doesn’t charge or power on. I think the battery might be drained. I disconnected the battery and tried a few troubleshooting things but the best I got was the power light to flash orange which I believe indicates that the battery is charging from a drained state. I have left it plugged in and tried different plugs etc but I get nothing. Is there a way to jump-start the battery? I would be happy to buy a replacement battery if I was sure that would fix it. I disconnected the battery and used the main power only all that worked was the fan at the bottom for about 5 seconds. That's the most I could get it to do. When I reconnected the battery and plugged the laptop back into the main power that's when the charging light flashed orange a few times. When I plug it in whether the battery is connected or not I get nothing. Is that normal? or should the laptop accept power from the mains if the battery is disconnected

It would have helped us to help you better if you told us what these things were, “… tried a few troubleshooting things…”. It saves us time. You may have done one of the steps incorrectly - none of us a re perfect.

Any how try the following and let us know how it goes.

To enter BIOS via function key

  1. Turn the PC off.
  2. Turn the PC on.
  3. The PC screen displays the Lenovo logo.

To enter BIOS via Novo button

  1. Shut down the computer. Find the Novo button.
  2. Press Novo button to enter Novo Boot Menu, select BIOS Setup to enter BIOS.

The Novo button is usually located on the side or near the power button of the machine. The button is either a small button or pinhole with a backwards arrow icon next to it that resembles an upside down U. To press the button, use the tip of an unfolded paper clip (or similar object with a sharp tip) and gently press the Novo button.

To answer one of your earlier questions.

Yes, laptops will work with battery removed and just the charger/power cord plugged in.

Have you tested the charger in another laptop? In troubleshooting you are always trying to eliminate possible causes.

Disconnected hard drive, removed Wifi card, take out the RAM and reinsert making sure it seats properly, what else??? This is to see if a bad component is shorting out the system

Did anything in particular happen before this problem first appeared?

Have you tried this yet?

  1. Unplug your charger cord.
  2. Remove the battery.
  3. Press and hold the "Power" button for 30 seconds.
  4. Now plug back in the power/charger cord.
  5. Try turning it on now.
  6. If it works put the battery back in.

Hi Mike I did try that and got nothing. When I did connect the battery after trying that I plugged it into the power using the charge cord and the charge light flashed orange a few times, that’s pretty much the only sign of life I can get from it. I believe the flashing orange light means the battery is drained

I just edited the above.

Have you tried the other things?

I think what you’re suggesting might be out of my expertise but I guess I can give it a try. I have used different charges and tested them on other laptops and they work fine. I have also tried the below suggestion and got nothing. Which makes me hesitant to just buy a $80 replacement battery

Unplug your charger cord.

Remove the battery.

Press and hold the "Power" button for 30 seconds.

Now plug back in the power/charger cord.

Try turning it on now.

If it works put the battery back in.

@oconnor84 I should have said "disconnect" battery, not " remove", as you don't need to actually take it out.

Thanks Mike. The problem I have is the laptop is 100% off and will not power on at all. When the laptop is plugged in the charging light does not come on either. I have disconnected the battery and plugged it into the main power and still nothing.
