Oh dear , plz forgive me guys I made a mistake...the EPROM was 24LC028

It looks like you need to reset the BQ2060SS IC, not the EEPROM. The
latter holds data pertaining to battery chemistry, amp-hour rating,
etc.

See http://www-s.ti.com/sc/ds/bq2060.pdf

================================================== ================
The bq2060 can be reset with commands over the HDQ16 or SMBus. Upon
reset, the bq2060 initializes its internal registers with the
information contained in the configuration EEPROM. The following
command sequence initiates a full bq2060 reset:

Write 0x4f to 0xff5a
Write 0x7d to 0x0000
Write 0x7d to 0x0080
================================================== ================

And Google Groups makes usenet (what you're *actually* reading) suck
royally. Google Groups has a broken interface. On usenet it's
customary to quote what you are replying to; on Google Groups you have
to hit "options" then "reply" to do this, rather than use the obvious
"reply" button. Quote, then trim away any excess, then put your reply
below what you've quoted (or intersperse reply and quoting, if
appropriate). This makes it easy to follow the conversation,
especially when returning to a thread you've half-read before and
you're only looking at new posts (Google Groups can't do this at all,
it just shows you the whole thread, but proper newsreader software can
do this and more).

You can access the same groups faster and more flexibly using a
dedicated usenet client, rather than Google's broken web interface. A
web search for "usenet" or "newsgroups" should get you started.

And the reason this is important is that Google does not actually host the
whole service and it does not reside on Google's servers (well, it does,
along with hundreds of others). Messages are exchanged among servers and do
not reach every server at the same time or in the right order. At any
moment, some readers of any thread are going to be missing some of the most
recent messages in it.

If Google ran the whole thing, everybody would be looking at Google's
server, which would always have all the messages in the right order. But
Google doesn't own Usenet, much as it would like to. Usenet dates back to
the 1970s and Google Groups is just one way to get access to it.

I don't completely agree. I agree that the quote is necessary in many
cases, but in Goldenshuttle's case, for example, IMO he did right when
he didn't quote, as his message was rather just thanking for Franc and
telling what is he himself going to do next, without replying to
anyone. Franc probably knows for what is he being thanked, and I don't
think that it interests others :-)

But even more annoying is to include a long "full-quote" without
clipping, and the most annoying thing is to write the reply above the
quote, aka top-posting. I have a statement "I don't help top-posters".

Really? And if I have to read more than a few lines to figure
out what you wrote that's new, or if it requires scrolling to
find it, I just skip past the message. I can keep track of a
thread myself, but I don't need to reread the same messages
over and over and over and over and over again.

If you really want to help us use google groups to its full
potential, please SPELL your words instead of making them up.
Somebody might google an expression like "how to reset EPROM".
They are very unlikely to try 2 figyour aut "how 2 reset
EPROM". It's not much harder to type "to" than "2" but makes
things so much clearer.

Yes, really.

But when quoted correctly (only necessary lines included, other
removed), there will be no more text to scroll than the text you _must_
read _before_ the new text, to know where is the new text replied to.
Then your argument isn't valid anymore. And the most annoying thing is
that I need to scroll down first to know where is the reply to, and
then scroll back to read the reply. Like in your message.

I can keep track of a
thread myself, but I don't need to reread the same messages
over and over and over and over and over again.


Yes, but including the quote below the reply doesn't make it more
interesting. And if the quote is after the actual message, it doesn't
mean that there isn't more of the new message below the quote, which is
below the first (and maybe the only) part of the new message. So you
must scroll down, however. And if you really think that the quote,
which you place below your message, is needless to read, why do you
include it at all?

And as I said already, a "full-quote", without any clipping, is very
annoying, independently to its place.
