I think this largely depends on state of main battery charger unit in PMU. If it's charging bat with Constant Voltage (~4.16V) from a 500mA or 1A source (host or OM-wallcharger) then the modem should happily survive a short period without bat - at least if it's not trying to send during this period (active cell handover, SMS, inbound call). OTOH if modem draws *too less current* (maybe related to sleep4 vs sleep2), MBC might decide to stop charging and cut the CV, leading to a glitch in modem's VDD and thus resetting it. It's very difficult to predict what's actually going to happen (just only guarantee is nothing will break), so I would recommend shutting down GSM prior to bat swap - alas this doesn't seem to work on SHR ATM. cheers jOERG signature.asc Description: This is a digitally signed message part. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: [SHR-Unstable] Battery Hotswapping
Well I tried disabling the GSM antenna in SHR-settings first, but it didn't help... ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: [SHR-Unstable] Battery Hotswapping
Yeah, I tried that, but it still would never come back for me. I still had to reboot. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
[SHR-Unstable] Battery Hotswapping
Hi. I'm trying to hotswap the battery in SHR-unstable, and it's not going well. The GSM chip never comes back online, and the phone section of the settings menu locks up when it tries to load the modules. I have to reboot the phone to get it to work again, and this makes the entire process of hotswapping a pointless waste of time. -- Thanks, The Digital Pioneer -- Please avoid sending me Word or PowerPoint attachments.
