Finding the part now we looked at it and found that we do not have that part on it but M4T28-BR12SH1 s instead. Having looked for a battery on the board and not finding one,just knowing that we're looking for a battery inside a chip was already really useful.
Thanks again (and to Dirk as well), Maren On 2/7/19 18:54, Maren Purves wrote:
Thank you! Would never have occurred to me.

Trying to boot it I found that it had 'forgotten' its boot parameters. It is supposed to have a replaceable battery and we found on part that looks like it may be a battery but with no part number or anything on it. None of the manuals I found on-line has a board layout with labels on it that would tell me where the battery is (assuming that the battery is the problem), or had any specifications for it. Pulling out another spare board, it behaved the same way. If we have to put any of these spare boards into use that would mean that they would have to have their boot parameters reinstalled each time we have a power glitch. That's OK for us here in the office/lab but not OK for people operating telescopes at night. Does anybody know and can either point me somewhere where to find this information - or have the information and pass it on? Thanks in advance, Maren Purves East Asian Observatory
