I was watching a video when without warning the laptop lost power. I check the power cord and outlet, that was fine. No lights on the led in the front when I press the power button. I am running Win.7. Any idea what the problem is?

Remove the ac adapter from the computer then remove the battery. Next, hold the power button for about 10 seconds, then only connect the AC adapter and see if that will power up the machine.

What is the service tag of this machine?

Wellsir ... that did the trick ... so I have a bad battery. I have it plugged in all the time so do I really even need a battery? I don't know about the service tag for it. Where would I find it?

Usually on the bottom. It's a 7 alphanumeric digit number. You can also get this by going to Command Prompt and type wmic bios get serialnumber

If you shut down the computer, remove the ac adapter, drain the power by holding the power button for about 10-15 seconds and then add the battery back in, then the AC, does it work?

Download and run this:

TSG System Information Utility
https://static.techguy.org/download/tsginfo.exe

For example running this on my Dell Latitude E6410 shows its "Service Tag Number" aka "s/n"

I haven't tried putting the battery back. I really didn't see any need to because I keep it plugged in all the time.

I tried your s/n at Dell but it does not recognize it. That is strange because it found mine.
I ran wmic bios get serialnumber and the result is the same as the s/n. You might try that to see if you get the same result.

I found that if your battery is bad then there is no sense keeping it in your laptop. Just recycle it. Of course I couldn't do that one time because the battery was an integral part of the bottom of the laptop. Without the battery there was an open area on the bottom. Also the battery had one of the laptops feet. I recycled the battery after I replaced it.

If you have a good battery then you must keep it charged. I had a friend that took out his battery because he always kept it plugged in. A few years later he put the now dead battery back in. The laptop refused to charge it and a message said it was bad.

You can take out the battery as long as you charge it occasionally but the the problem is remembering to do it.

....
It looks like the machine had its motherboard replaced. When you replace a motherboard it will ask you for the service tag but whoever set this up put the the serial code of the motherboard, not the actual service tag. The machine model itself is a few years old so more than likely no warranty.

@spirittoo I suggested putting it back in because the issue may just been a glitch and removing all power sources may fix it. If it works, then you can run the BIOS diagnostics (F12 on startup, choose Diagnostics), or even check the BIOS menu for the battery information and see if there are any issues. While it make sense to leave the battery out if you don't use the laptop away from the desk, if you have a power cut or the ac is disconnected then you will lose what you are working on. Something to think about.

Wellsir .... I put the battery back in and the machine still boots up. I ran it a couple of days to see if the problem come up, but so far I haven't. I will check in the bios when I get the chance.

You may be right about the glitch ... I ran the diagnostics and it found nothing wrong. No mention at all about the battery.

Were you able to confirm the battery health? You can find that in the BIOS if you don't want to run the diagnostics again.

I didn't get a chance to go into the bios. The laptop would not power up again and I had to remove the battery and repeat the procedure you told me about. I guess that is a good indication there is an issue with the battery. I have the laptop plugged into a ups, so I don't know if I really need the battery.:unsure:

Other than being portable or losing ac power for any reason then there is no real need that I see since you are not moving around.

Wellsir ... I'm still having a power issue. I tried to boot up the laptop with the battery out and got nothing. I had to put in the battery, with the power plugged in, tried to boot ... got nothing ... then I removed the battery and power adapter, press the power button for 10 sec, plug the power back and it booted. Something else must be going on. The question is what?:unsure:
