I am rebuilding this battery, the board inside the cell pack is having
an 8 pin EPROM type 24LC028.
one article on the net says this EPROM is set 2 allow 500 charge cycles
and then gives instruction 2 stop or declare battery dead. OK, does
anyone have advice how 2 reset this EPROM ? there is a comapny selling
the EPROM reprogrammer, but I hope someone can suggest something
cheaper. Thanks alot.
DDR notch or key compared to DDR2
that doesn't show up on their website. The notch/key in the sodimm is a
smidgeon further to the edge than a known DDR sodimm. It is so close
that visually they look identical, until you try to seat it. Then the
notch is maybe 1 or 2 millimeters further to the edge of the sodimm.
I think this is DDR2, but can't be sure because I don't have a DDR2
machine. Can someone confirm this?
Thanks in advance
Re: DDR notch or key compared to DDR2
The connector on DDR2 is dramatically different, I believe. Not only
the notch but the number of pins is not the same.
There are a ton of memory types (Fast Page, EDO, SDRAM, DDR, DDR2, there
is even SO-DIMM RDRAM (Rambus)), so all that you can really say is, it's
not standard DDR.
