Elitebook won't boot- flashing power and battery lights

[quitotina]

Please help!  I got a factory refurbished Elitebook 840 at the end of December (so I've only used it about 6 weeks).  It was working great, but then started losing battery quickly.  Then suddenly it won't turn on.

Per directions found here I tried discharging the battery, but when I reconnected it and pushed the power button the power button and caps lock keys started flashing white.  On the front of the computer the charge light is flashing orange and the power light white.

I don't want to do a reset since I can't lose all of my information.  Any help, please?  Thank you!!

Can you match with anything on the above linked page?

A reset does not automatically lose you all your data, so....

Press and Hold the PWR off button for 4 seconds to force a PWR off.

Unplug from the wall.

If you see a battery compartment door, your computer has a removable battery. Remove the battery.

This is valid for most notebooks;

Press and hold the power button for 15 seconds to complete the reset.

Re-insert any battery you removed.

Try and tell us of any changes please.
