The top right "scroll up" button got stuck on and it was constantly scrolling through the screens. I reset it to get it out of this screen but now it won't turn back on. I've tried all the obvious things (powered from mains, USB, reset, etc.) with no luck.
Any idea?
Did you try a soft reset:
With the unit in hand press and hold the mode reset and power buttons all at the same time. Hold these for 3 seconds and then release.

I've had this Garmin for almost three months, and it has worked fine. Today it suddenly could never locate satellites. I turned it off and on, but it still could not find the satellites. Oddly enough, when I put it on this morning, it asked if I was inside. It has never asked that before.
Hey, I install Garmin GPS Chipset Type G and now it seems work well.

change Battery in garmin forerunner 305
Might not be the battery.My wife's was always powering off during runs. Then it would not power on at all. There was a connection inside that wasn't making contact. But first First try cleaning the 4 brass connection tabs on the watch and check your charger to make sure the tabs are raised and not squished. Second try to reset the unit. Hit mode reset and power buttons all at the same time. Hold these for 3 seconds and then release. If these do not work here is what I did. There are no screws holding the unit together. I used a exacto blade to very carefully pry the unit apart along the side seam. It's not easy to do. Be very cautious and gentle. Work the thickness of the blade into the joint to gently wedge apart. You are not trying to remove material! Once apart you will see some brass fingers that make a connection between the upper and lower part of the unit. This is where the problem was with my wife's 305. I gently raised these tabs to make a better connection, It's been working ever since. I didn't try it before but try pressing very hard on the unit where it says Forerunner 305. The case is very hard so it might not work. But if it powers up when pushing you found your problem. Hope this helps.Here is a link I found on opening a 205 (Same process) http://ctorunner.googlepages.com/dismantleforerunner205 To put the unit back together use Automotive silicon/gasket maker.Use a tooth pick to put a VERY small amount of silicon around the entire seam. Put the two half's together and wrap tightly with electrical tape. Test the unit immediately to see if it powers on and off. If it does not open it back up and raise the small prongs more that make the connection from the bottom half to the top half. If any silicon squishes out the sides wipe with water and a rag.Let the unit sit over night. In the morning remove the tape.

When I plug my 305 into the computer, it opens the window for Training Center, and then a message appears: There was a problem while communicating with your device. Please make sure it is connected to the computer, then try again.
It just started this after 15 months without a problem. I also sometimes get this message: The remote could not be resolved or something to that effect. Thanks.
I am new to the Garmin Edge 305, and started getting this problem yesterday. Indeed, yesterday it was the first time that I downloaded Courses.
I followed the Guest solution, deleted all new courses from my Garmin, and it now WORKs!!!!
Uploading my courses back again to the Garmin made the problem return back. I need some more work to identify the bad course.

My forerunner 305 won't charge without major manipulation of the cable (ac or usb) into the cradle. This seems to be a problem with other models as my 201 did the same thing before upgrading. Any suggestions?
Question: My Edge or Forerunner 205/305 won't power on. Is there a soft reset that I can do?

Answer:
If a Forerunner or Edge 205/305 is unable to power on, a soft reset can be performed to un-freeze it. This will not erase any user data and is most effective if the device is connected to the computer while performing the reset.
To reset the Forerunner or Edge 205/305:
In addition, please make sure that the device has the latest software version

Thank you for helping with replacing the battery in my forerunner 305, but I would like to know what adhesive you used to re-assemble the top.
Thanks

Hi F-Phil
what kind of battery did you use to replace the original battery in the Forerunner 305. The Garmin 361-00026-00 seems not available, at least a web search did not come up with any results.
I have seen somewhere else (http://ctorunner.googlepages.com/dismantleforerunner205) mentioned that the Forerunner 305 battery look like an IPod (generation 4) battery. But so far I have not found any information about the size of these batteries, i.e. if they match the approx. 40mm x 35mm x 5.5mm of the original battery.
Cheers, Stephan
It's not always the battery, I assumed it was and opend mine up to check it out but the battery was OK.
Problem was the unit wouldn't start without pressing mode + reset followed by the power button.
I lifted the internal watch contact strips to put a better connection between the two halves but that made no difference.
I found that I couldn't delete all the history and the watch had recently turned itself off on a run after giving a low battery warning => the history was corrupted and caused the watch grief.
The only way I found to delete the history was to load a v 2.80 (or earlier) version of the watch s/w (current 2.90 doesn't delete history and there is no tool to do it!)
Fortunately I had a copy of v2.80 but the old version is not now on the Garmin site (that I saw).
Moral of the story, don't run your battery low for two reasons, Li-ion batteries lose capacity if you run them below ~30% and also if the watch "low battery" turns off while recording it can corrupt the history and really upset the watch.
At least I now know how to open the watch and have found plenty of possible small mobile phone batteries that will fit (Samsung have a few possibilities). The ABSOLUTE max size of a replacement battery is 36mm H x 43 mm wide x 5.8 mm deep.
If you go 43 mm wide you have to trim a couple of internal plastic ridges in the case.
Good luck and try starting after pressing mode + reset if it won't fire up then try and delete all the history.
Also DON'T run the battery low if you want it to last, Li-ion work opposite to NiCad and NiMH which should be fully discharged before recharge. You try and keep them above 50%.

It is only a year old.
I have had the same problem. To fix it, I simultaneously hold down the "mode" and "reset" buttons for about 10 seconds. After releasing the buttons I power it up as normal. This has worked both times it has happened, and I got this fix from the Garmin website. My mileage totals are still in the history.

When uploading from my Garmin Forerunner 3o2, I nearly always have to synchronise a number of times in order to get the message "...successfully received from your device". I usually get "Problem receiving activities and courses".
This turned out to be corrupt data on my machine. I opened the Garmin traing center, backed up all the courses then deleted them inside the Training centre. I then received from device and all was okay.
