Windows 7: Unable to boot from battery power

Unable to boot from battery power

I'm suddenly experiencing this problem. I'm unable to boot my laptop from my battery. But if I connect the power chord, I'm able to start it. There is no problem with restart, hibernate and other options on battery though. I've also installed batterycare to check the battery condition. It shows no problem with battery condition. Can anyone help me out with this problem?

Do you have access to a digital multimeter my friend as it will show you if the thing is ok on voltage or not .

Having said that it might e holding a voltage but no current capabilities - how old is it? as Lithium batteries degrade from the day they are manufactured mate. On average that can be around three years. I personally would not rely on the battery health readout an actual check is best.

By he way depending on the make and contact set up check out too if there is any debris down inside those slots either in the battery (usual) or the machine.

@ ICit2lol:

The battery's 1.5 years old. There is also no debris. I don't have voltmeter mate. Is there any way other than this?

Well it shouldn't cost much at a tech or any shop that sells batteries rsn to stick a meter on it for you.

Just because it is only 3 years old doesn't mean it should be ok mate.

The thing is if it will not boot from the battery there is only two real causes 1. the battery is dead 2. the machines battery connection point is not connected to the motherboard supply point. I think it is the battery that is at fault unless that test wherever you can get one done comes up with no fault.

Can you send a pic of the battery and what machine are you operating? Some specs would be very handy.

What happens if you start the system connected to AC then disconnect the AC. Does the system shut down almost instantly? Or last a very short time before it shuts down, 5-20 minutes?

If either of those things happen then you need a New battery as it does not hold enough charge to keep the system running. And when starting the system it uses the most power to get everything running so with a weak battery it simply does not have enough charge/power to start everything up.

I find that sometimes this will help; Shutdown the computer, remove the battery for about 30 minutes then reinstall and let it charge for about 1 hour, then turn on the computer.

@ Edwar:

There's no problem with the battery once the system is on. Once I plug the ac and start the system, and remove the ac, the battery works just fine as always. The only problem is with boot Thanks for your help
