H500 does not turn on

If you have a drain on your battery , it would not take 18 months for the battery to go dead . What do you mean The battery gauge in the dash shows only about 1/2 power, When ? When the vehicle is running ? Not charging ! The battery gauge as you call it has nothing to do with the Battery . That's showing how much the charging system is putting .The volt's indicator is controlled by the PCM - engine computer . With the engine running should show 14.1 volts .if your only seeing 7 the charging system isn't working. The alternator is controlled by the PCM as well ! Have it check by a GM dealer .

Yep It sure does Why didn't you charge the chair for 2 months? Charge at least once a week if you don't use it daily. Always break in the new batteries by using the chair daily for 10-15 days charging everynite then charge once a week if it sits for that long without use. Always put up fully charged. Do this and your batteries should last 3 -4 years Charge overnite if you use daily and never charge more than 24 hours Good Luck

The battery has lasted at least 8 years. It has reached its end of life. There is no battery that lasts forever.

It's eight years old now, and if as you say it has had intermittent use, then the battery will probably have died unless charged at last once a month.

It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

sounds like the coils inside the air handler/furnace are freezing up. likely cause is the freon charge is incorrect (probably undercharged). it may have been correct when the tech did the work but some may have leaked out. it is slightly possible too that the system is overcharged. you should have the system pressure verified, and then have it checked for leaks.

That's one of several problems my Stiletto 2 has. The only solution I've found is to "reboot" the unit. You'll have to remove the unit from the cradle, pop the back off, and remove the battery for a few seconds. Then put everything back together and power it up. It will take a minute or two, but once it reboots it should be fine.

i opened the unit up, removed the covers and disconnected the ribbon that goes from the main board to the lcd screen, cleaned it and then reinstalled it. i then put the unit back together and it has been working fine for about 2 months. let me know if it works for you too!! good luck. dave

don't know if this will help,

I had this same problem a couple of months ago, battery appeared to be charging but got emptier and emptier, tried different chargers and no improvement etc.

Friend has same phone, used their battery in my phone which was charged and phone was working fine, meanwhile, charged my battery in their phone and it charged fine and then for 2 months no repeat of the problem...

then last week, it happened again, trouble is this time i'm on school holidays and can't use the friend's phone for another 3 weeks!
