My VGN-FE21M recently awoke from Sleep for me to find that "No battery is detected".
This was a complete suprise as it was operating fine. Once a month I completely discharged the battery and then fully charged it.
I have reinstalled Windows Vista too make sure it wasn't a software problem and still it doesn't detect the battery.
Is there any way to test the battery to find out if I need a replacement?
VGN-FE21M
Windows Vista Ultimate
Intel Core Duo T2300 1.66GHz
1GB DDR2 RAM
160GB Hard Drive
nVidia GeForce Go 7600 with 128MB RAM
Battery: VGP-BPS2C
Purchase date approx: August 2006
Any help would be greatly appreciated. Many thanks.
Hi tpmann and welcome.
I suppose the only way to test if it is the battery or a software problem is to go to the Sony Centre or PC World with your Vaio and ask if you can borrow a working battery for 10 minutes!
Does the battery show up in Device Manager?
Thanks for your help.
Under "Batteries" in Device Manager there is:
Microsoft AC Adapter
Microsoft ACPI-Compliant Control Method Battery
I'm guessing neither of those is the actual one inside my notebook.
Is it normal for a battery to die after only 1.5 years? It just stopped working rather than deteriorating over a period of time.
Cheers,
Tim
Hi Tim,
Device Manager seems to know there is a battery attached. Try right-clicking on 'Microsoft ACPI-Compliant Control Method Battery' -> Choose Uninstall and reboot the Vaio to reset the drivers.
Most Lithium Ion batteries have a life of 300 to 400 charges - so it depends how often they are cycled. Unlike Nickel Cadmium batteries they have no 'memory effect' so there is no advantage to carrying out a full discharge and charge - it just uses up another charge cycle. It is a little unusual for a battery to die after 18 months but by no means that uncommon.
As I said, the only way you will know is by trying a good battery in the Vaio and seeing if it works OK or not.
I have exactly the same problem on exactly the same machine VGN FE21M at approx exactly the same date... since a few days?
Please let me know any outcome!
Regards and a happy new Year!
Exact the same problem with my FE31Z on Vista. Has anyone found a solution?
Just had this happen today on my 15 month old FE31Z upgraded to Vista Home Premium. Battery part number is VGP-BPS2C.
I'd like to know whether I need a new battery or whether my machine needs a repair.
Is there a trend emerging here?
At my end it was the battery!
Regards
Exactly the same happened to my VGN-AR21M running with a VGP-BPL2C battery on 27.01.2008 with Vista Home Premium. Battery is approx. 1 year old and suddenly 'died' after restarting.
Seems suspicious to me.
Ok running on the original battery supplied.
