Question about Garmin eTrex GPS Receiver

1 Answer

Won't come on at all

I've had the blue version of the eTrex for several years now. I made the mistake of leaving batteries in it for an extended period of time. It worked fine before, but the batteries corroded. I cleaned the corroded area with white vinegar, and it cleaned up pretty well. I couldn't see any areas where the metal was pitted or where it should have interrupted any circuits. I've tried a couple of new sets of batteries, and it won't come on at all. Any suggestions would be really appreciated.

    thanks for the suggestion, but the contacts are nice and clean now, even to include the length of the exposed circuit in the battery chamber. I'm pretty sure the problem is beneath the battery chamber, in the circuit housing. I think the corrosion wept through one of the holes where the power from the batteries goes through the water resistant casing to the circuitry. Any ideas how to open it up, or what to do once i get there if this is the case?

Try using metal sandpaper to rub off the contact points. This might help.

    Sorry, Chris, but I can't help you any further. Maybe someone else knows the inner workings and can help. I know all about the software and can help there, but internally, can't advise. Sounds like a trip to the Garmin Dr. is in order shortly.

    You might want to ask on a few of the various GPS forums. Search for threads where the folks have actually opened up a unit and they might be able to guide you.

1 Answer battery is not charging and even when i plug into power it rfuses to come on HELP!

If the laptop has been non stop plugged in for extended periods of time (leaving it plugged in for days at a time for a few months or years) then the batteries will loose their ability to retain a charge.

The only solution to this is to buy a new battery.

Also check the cable for any damage. If a new battery does not work, it is possible that the computer may have overheated and has been damaged

The blue light on the charger will not light up anymore and my guess is that it's broken, but it hasn't even been a year yet.

The most likely scenario is that you need a new battery. Before making that decision you should run some diagnostic tests. It's possible that the battery has completely discharged and is struggling to begin charging again. Try some of these approaches.

1. Download and install BatteryMon 2.1 from this site:

2. Run BatteryMon.

3. Look to see if BatteryMon can recognize your battery and if the battery is charging.

4. If the battery cannot be recognized you should try plugging and unplugging the battery to see if you can get BatteryMon to recognize the battery. If you have no success skip to step 6.

5. If the battery is recognized but won't charge, then you should shutdown Windows with the battery installed and try and charge the battery with the computer off but plugged in. If you still don't see a solid light indicating the battery is charging, take the battery out and plug it back in; several times if necessary.

6. If you still have no success try this similar method:
6a. With the computer powered off remove the battery.
6b. Power it on and leave it for a couple of minutes until it fully boots up.
6c. Carefully slide the battery back into the computer and leave it on for 10 minutes.
6d. If you're lucky the battery should now start to charge (if it does leave it charging for at least 3-4 hours straight and you should be back in business).
6e. Repeat this process several times.

7. One last method to try is the freeze method.

7a. Take the battery out and put it in a zip lock bag. Remove ALL of the air out and seal it.
7b. Place it in the freezer for 2-6 hours and take it out.
7c. Place the battery in the laptop and connect the charging cable while the laptop is OFF. Wipe all condensation off the battery as it forms with a paper towel.
If all goes well, you should be able to bring the battery back to life. This usually happens when you let the battery reach 0% and don't charge it for an extended period of time.

Hopefully one of these approaches will cause your battery to begin charging.
Good luck and thanks for using FixYa.

HP Ipaq does not turn on

Ufortunately, the battery is likely the culprit.
You can try removing the battery overnight, then leave on charger for at least 12 hours.

These batteries generally require replacement every 1-3 years. They deteriorate quite rapidly if left unused/uncharged for extended periods of time (like a year!)

Unit locks out fine blue line appears have to remove batt and then turns on

Disable the WAAS on your unit. A new satellite was launched earlier this year and is causing a problem. This is why Garmin issued a new software update version 3.9.
Menu > Setup > System... scroll down to WAAS and disable it. This should get your unit working again but with less accuracy.

Update the software to version 3.9 and leave for about 20 minutes in open area (clear view of sky) so your unit can download the full almanac. This should permanently fix your problem. Once you finish upgrading, go back and enable the WAAS.

to mhotz: You can purchase serial2USB connectors at a computer store. You will have to install the drivers which come with it before it will work. That should solve your upgrade problem.

I had this problem today, updated the software, now the unit seems to be working perfectly. The unit "crashes" (single line down screen center) as soon as it get enough satelites to work with WAAS.

Go to Garmin site for software updates. Download and install the WebUpdater. Once or unit is hooked up to your computer and you have internet access, the software will download and update your GPS with the latest software fixes. I had software Version 3.7. For the Legend, Version 3.9 fixes the problems with WAAS.

Plazma burn in from video games

Plasma burn-in occurs when the same picture is on the screen for a long time. You should only have a problem if you leave the WII on a menu for extended periods, or leave it paused for extended periods. Be careful about that, and you should be fine.

Do the following: 1 - Make sure you have fresh batteries in the unit and turn the unit on. 2 - Check the GPS date and Time. On the Main Menu at the bottom of the screen, you can see a date and time. If the date and time are not current, then the clock is your problem. You will have to wait for the almanac information to be updated. Details are below in a later section. 3 - Make sure your GPS is in the Normal Mode and not a demo mode. Verify other systems settings. Go to the main menu and click on Setup icon. From the Setup screen, access the System screen icon. Verify the following settings: GPS: normal WAAS: Enabled Language: English or your choice. Battery: Set according to your battery types. 4 - Check your GPSs Version Software. Go to the main menu and click on Setup icon. From the Setup screen, access the System screen icon. From the System screen, access the sub-menu icon in the upper right bar. Select "Software Version" from the list. Verify the actual software version for me. The latest version available for the eTrex Legend is version 3.90 dated March 2008. Update the unit using this latest software and using Garmin's Webupdater. If that won't work, use the following download page to access the latest software updates per units. 5 - Resetting your GPS clock and almanac information Next you may need to acclimate your unit to a new date and time (almanac information). If you had your unit off and without batteries for over a month since you last accessed satellites, then your clock and almanac information may be incorrect. Even Garmin acknowledges this problem after software updates and the problem with accessing satellites. They state: "unit data including alamanac information may be incorrect or cleared. Back up all user data before upgrading. After installation is complete, place unit with a clear view of the sky for 15-30 minutes to re-acquire almanac data. " I know of no way to reset the clock using the GPS menus. All I can suggest is that you do the following: A - turn the unit on and wait 5 minutes or so for the "Poor Satellite Reception" screen to appear. See page 7 of the owner's manual. B - Set the "new location" to your area using the map when the "poor satellite reception screen" appears. Be sure to use the "map" option and not the "automatic". C - Set the GPS outside with a clear view of the sky. Check on it every 10 minutes. When the "Poor Satellite Reception" screen appears again, then click on "Restart Search". The "Restart Search" option is used when the date provided in the GPS is not today's date. (See page 7 of the Owner's manual for an example) Legend Owners Manual: D - Once the GPS can track 4 satellites, then the clock should reset and you should be fine. This process could take up to an hour. I have had this problem with my eTrex Vista and eTrex Legend (both backup GPSs) and resolved it by having the clock reset. In fact, I just tried my eTrex Legend today after not using it for many months and storing it without batteries and it had this same problem. I followed the steps above to fix the problem. This took about 35 minutes.
