plugged in not charging ? bios flash without battery ?

When in doubt go to LINUX. http://askubuntu.com/questions/27065/brand-new-battery-is-100-charged-but-at-0-capacity

The  BIOS isn't the issue - you have a hardware problem.

And the requirements are there because a power outage during a BIOS flash can permanently render the mainboard unbootable.

have you tried holding the power button down to reset the bios or remove the battery completely and plug it in using AC only power.Then try to update it?

another thing to try is to disable the Microsoft ACPI-Compliant Control Method Battery under battery in the Device Manager then try the update.

I have tried all these long time ago.  dell support need to make a bios flash without the battery and charger limitations. they just dont want to do listen

https://wiki.ubuntu.com/DellBIOS

if you have access to a battery backup that works.

the problem is not the lack of adapter, the problem is the bios disregards the adapter (can not define it) running the computer without a battery it still turns on.. ie adapter works. the circuit inside the machine does not set the current to charge the battery, in windows the battery says 504 hours left 19% battery and does not indicate the plug being in or charging taking place. i feel that the problem (though perhaps has been defeated by flashing, i do think the flashing is unnecessary. i feel that the unit on the mother board is just triggered as full or has gone into a safety mode due to a short. i feel that in time it will reopen the circuit. though i have removed all power and bios battery, i think i need to do this for an extended period of time so the flea power is exhausted. alas i think my laptop is actually not going to do this even though i have seen many computers recover within minutes of this problem. if anyone has had this 509 hours left 19% (numbers not relevent) problem and recovered it let me know. ps i set bios to charging behaviour enabled, and in windows i set the charging to enable, i have uninstalled and reinstalled the battery controller.

I also have similar problem with my dell inspiron 1520. I see close to 4000 hrs with 62% battery charge.. The battery does not get discharged but also not charging.. I am not able to update service back as my system is showing as running on battery. As soon as I unplug the charger, the system turns off.. Really bad of Dell.. 

This may help in some cases.

I had the same error about not charging. I knew the battery and charger were good - they worked on a different M1530, and charged.

Figuring I had nothing to lose, I downgraded the BIOS from A12 to A09, and the issue was resolved.

EVEN THOUGH I WAS ABLE TO FLASH NEW BIOS WITH BATTERY AT 2% PLUGGED IN NOT CHARGING BUT IT DID NOT SOLVE THE ISSUE. MAY BE BECAUSE I FLASHED A08 ON A08(I DONT KNOW IF UPGRADING A08 TO A09 SOLVES IT OR IF ITS EVEN SAFE? [I HAVE DELL INSPIRON 15R 5537] ANY ADVICE OUT THERE WILL BE HELPFUL). REINSTALLIG WINDOWS AND UPDATING DRIVERS INCLUDING THE BATTERY DRIVERS ALSO DOES NOT HELP.

ANYWYS HERE IS A TUTORIAL FOR THOSE WHO WANT TO GIVE IT A TRY ANYWAY.......

STEP 1

MAKE A BOOTABLE USB

http://www.dell.com/support/article/us/en/04/SLN143196/13

STEP 2

DOWNLOAD BIOS FROM DELL SUPPORT AND PASTE IT INTO THE BOOTABLE USB http://www.dell.com/support/article/us/en/04/SLN284433/13#How_to_update_USB_flash_drive

(STEP 4 ONLY IN THIS TUTORIAL)

STEP 3

REBOOT THE SYSTEM AND INSTEAD OF TYPING: Diag C:\> O9010A12.exe  (AS INSTRUCTED IN THE ABOVE TUTORIAL)

TYPE: Diag C:\> O9010A12 /forceit

(WHERE O9010A12 IS BIOS NAME THAT YOU DOWNLOADED INITIALLY)

AND HIT ENTER

ENJOY!

(MAKE SURE YOU DO NOT HAVE ANY POWER CUTS OR REMOVE YOUR AC ADAPTER WHILE THE BIOS IS BEING UPDATED OR YOUR LAPTOP WILL BE BRICKED AND BECOME A TOASTER)

I  don't  take  the  time  to  reread  all  the  posts . I  think  I  remember  this  thread . Your  problem  could  be  the  cord,  the  power  board  'that  is  the  part  on  the  laptop  you  plug  in  to  ', or the  battery . You  can  test  the  cord  with  a  continuity tester . You  may  need  a  paper  clip  to  reach  each  pin . They're  videos  on  how  to  do  this  I'm  sure . You  may  just  need  to  clean  off  the  connectors  on  the  battery . You  can  do  that  with  a  pencil eraser . If  you  have  a  laptop  you  can  test  the  battery  on  try  to  see  if  you  get  charging  icons . If  the  power  board  on  your  laptop  is  separate  from  the  motherboard  it  may  not  cost  much  to  replace . Laptop's  are  very  fragile . I  wouldn't  recommend  opening  your  laptop  without  experience . It's  not  like  a  desktop . Desktops  are  simple . It's  too  easy  to  break  a  laptop . I  know  I  was  searching  for  this  topic  with  a  certain  laptop.  I  read  somewhere  that  the  power  board  would  stop  charging  if  you  had  old  bios.  That  could  be  part  of  the  problem  in  some  cases.  If  your  cord  test  bad  replace  it  with  a  cord  with  the  same  voltage  and  amps . It  will  say  on  the  'brick'  power  supply  what  you  need .

A big question with a simple answer:

Open a command line as Administrator. Put your BIOS file (say "1750_A06.exe") into a simple temporary folder in your root drive. It could be for example: "C:\temp" (You can rename the 'temp' folder whatever you want).

And finally put this command into your CMD: C:\temp\1750_A06.exe/forceit )

Be careful not to put any space in between

cinfirmed  /forceit    starts the bios update without batery inserted.

 This is the one!  I follow this simple steps an really work! Thanks! Thanks! Thankssssss!
