The battery on my 2 year old, out-of-warranty, Dell Inspirion E1505 was
almost dead ( about 6 min. charge retention). A new Dell battery was
around 200$ and hence I bought a replacement battery from Kahlon
(guaranteed to be E1505 compatible) for half the price.
After I swapped in my new Kahlon battery my Dell beeped on boot-up and
issued a warning of the sort: "Unrecognized battery type; Will not be
able to charge". Pressing F1 allowed me to ignore this and continue. I
kept the AC charger connected for about 12 hrs to get the battery its
recommended initial charge. Subsequently I disconnected AC power and
proceeded to work on the battery till it drained fully (about 4 hours).
Laptop worked fine. (all the while the battery charging LED blinks
green/orange)
On next recharges same warning recurs. F1 allows me to bypass. Only
difference now the battery does not charge at all. On AC adapter
disconnect the laptop immediately dies. Double clicking on the power bar
gives me all the battery details including Amp-hrs, manufacturer etc.
Charge %age always remains at zero.
I have no clue how to fix this! I suspect its the right battery but some
Dell trick that prevents me from using anything other than their
expensive "official" battery. No proof but a strong suspicion. Unfair.
Debug steps so far:
1. Tried booting from a Knoppix Live Linux CD. Still same warning. Will
work only so long as I have the adapter. /proc/acpi/battery recognizes
all battery details. Charge %age remains zero.
2. Tried BIOS. No battery recalibration options. No user-changeable
battery settings at all there. Probably Dell "sanitized" the BIOS to
some custom-version.
3. Only one BIOS flash upgrade listed on Dell website for this model. Its
only an optional update. Too chicken to try it yet lest I end up with an
"expensive doorstop"
Any help at all is greatly appreciated! If I can help it I do not want
to pay Dell 200$ to inject new life into a laptop that cost $700 2 years
ago!
