Default 8300 charging by PC -- a non-no??

Please Login to Remove!

I heard something funny from my IT dept. that I wanted to run by you all.

They were emphatic about not charging the 8300 from my office pc, asserting it could do damage to the battery (although they didn't say how/what damage would occur). This was in the context of my switch from a 7290 to the 8300, which now syncs wirelessly, and their trying to convince me to never hook up the 8300 to my PC.

None of this makes any sense to me. I can understand the 8300 charging slower due to lower USB power delivery, but I don't see how this can damage anything -- particularly where BB provides USB connectivity in the 8300 design. I also don't see any reason why I can't connect by USB to do things like back up, application loading and use of the BB media manager for mp3 transfers, as long as the "auto sync" feature in the BB desktop software is disabled.

What say you, oh learned members of the Collective?

Thanks,
Mark

never heard of that. "may be" the IT don't want people adding applications and syncing other stuff. They might be avoiding to give technical support if any woes occur.
Of which it don't make sense because they can push IT policy to block it

The first time I plugged my 8300 into both my work and home PC, I saw a notice that indicated that the power was not sufficient to charge the battery. However, I kept it plugged in, and continued to plug it in, and have never charged the battery any other way. I have never seen that warning again.

If that is the issue, and it is real, getting a powered USB hub should resolve it.

Before you try to charge your Blackberry via your USB, you should install the software as I turns on the higer voltage required for charging your device. I do not know what your IT department advised to not use your computer for charging but it was not for the reason they gave you.

I suspect the USB put out less power that the wall charger so it hurting the battery is bunk! I do think they do not want you to make any changes on your device via your computer.

Looking at my post, which I threw out looking for clarification on a thought, I realized it was worded pooly. I should have said:

Where I work, ever since they started to sync the calendars wirelessly, people have questioned the need to plug the BB into the computer. But we have not been told "not to".

On the other hand, our IT policy is so restrictive, harming the BB by using the USB would be difficult. (not impossible for some of you hackers I'm sure, but difficult for normal people to harm it by doing something stupid)

Default A final follow-up

The 8300 works fine with my USB line to my PC, both for charging and for working with the BB Desktop Manager program (even though the unit is set up for wireless sync) -- so much for the IT dept. horror stories. All I had to do was, before plugging in, deselect the "automatically synchronize" option in the Desktop Manager.

So, now I have full access to the Desktop Manager backup/restore program, applications loader and music transfer applet. Time to go find out what new apps are out there since the last time I looked a couple years ago with my 7290 I wonder if BBLight is still out there???

Thanks for this, I've been having the current error when trying to charge over USB. Didn't think to install the software.

Normally you'll only get the "insufficient power from your USB port" message during PC startup or reboot, when the system POST sequentially initializes the USB ports first with serial data then secondly with power. If you leave your BB connected to a USB port and deliberately reboot, you'll see the message sequence on the BB screen as the USB port goes thru its initialization process.
