Is it battery or laptop?

...today I went to turn the laptop on and it was dead. Tried 2 chargers and got nothing at all.
I unscrewed and removed the battery, plugged in charger and it started up.
After laptop started up, a game my little one was playing was still on.

So my thoughts are battery is faulty and this is the 2nd time this has happened.....

As you removed the battery, but it still resumed from where you left off, then it must have been set up to hibernate when the battery dropped to a critical level.

As it would not start up with either charger, then the battery is the prime suspect.

However, there is a possibility that the battery charge was so low that the charger(s) may not have been powerful enough to both charge the battery and start up the PC. Did the charging LED come on when you plugged in the charger? If so, did you wait for a while to let it charge up a bit?

I have seen this on a Dell with a perfectly good battery. After accidentally letting it discharge to 1%, with the charger plugged in it would not start up until the battery had charged for a few minutes and got up to about 3% charged.

For more details on the battery health, try generating a Battery Usage report....

Generate Battery Usage Report in Windows 10

The power LED did not come on...

That does make the diagnosis that the battery is at fault more likely The power settings should not affect whether the battery charges while the laptop is turned off.

It would still be worth generating a Battery Usage report. That will tell you, amongst other things, the battery's current full charge capacity vs. its design capacity.

Bart,

You need to check what the battery is currently capable of charging to.
- The 100% etc you see in your Windows taskbar Notification area [SysTray] are comparisons to the baseline of what it is currently capable of. So, for example, a worn out battery might show 100% but that just means that it is fully charged to the level it can currently achieve and not it is fully charged to the level it was designed for.
- To understand how worn out the battery is, you need to find out the ratio of Full charge capacity divided by Design Capacity
- I posted a bit more about the subject in my ditty This is how you can decide if you need to replace the battery [#11] - TenForums

To get the ratio, run a Battery report using this command [but with the path to a convenient folder of your own instead of my D:\Desktop]

Code:

PowerCfg /batteryreport /output D:\Desktop\BatteryReport.html /Duration 1

You can run the command in a Cmd window or a PS window. It makes no difference.

You'll see the two parameters you need in the second section Installed batteries

Thanks the battery is only 3 months old.
I guess charging levels would not explain it NOT turning on at all even when plugged in right?

ive run the battery report which is atatched and design full charge capacity is the same

any thoughts?

otherwise Im sending the battery back

I have an i5 Toshiba L50 laptop, so rather similar to what you have and a very similar age.
Still on the original battery which I estimate to be around the 20%-30% full charge capacity mark now. That is gleaned from using it.
Indicators as below are all wrong so I would not place any faith in those.
Windows battery report or the Toshiba Health application is not useful.
Windows battery report indicates 70% of original design capacity and has done so for many years, it is stuck on that value. No idea why but it is obviously not true.
The Toshiba Health application, used to be more accurate and battery health has changed from poor 30% back to fair 70% now, obviously impossible.
Other applications like HWMonitor indicate exactly same as Windows i.e. 70% capacity again stuck value.
Just passing on info, I have no idea why all indicators are wrong.

Helmut,

Thanks for passing that info on. I have never seen a report of the Battery report Full charge capacity parameter being stuck before. I'll keep your report in mind.
- The only false data I have seen has been a Full charge capacity that is about 150% of the Design capacity. This is also clearly rubbish but that particular tablet-with-keyboard was made by a bunch of useless clowns anyway [No, not Dell. Another bunch.]
- I don't know [yet] if it is stuck there because I don't use it on battery power very much.
