AC adapter not charging system

Turn the remote upside down. At the bottom, there is a slot that opens the battery tray and a series of grooves that are part of a clip that releases the tray. Insert the fingernail of your thumb into the grooves and the fingernail of your index finger into the slot. Ease the grooves (clip) toward the middle of the remote and slide the tray out. There is a ridge in the tray that matches the battery only when the battery is in the proper position. Slide the tray back in. If the remote doesn't work, you've probably inserted the battery in the wrong position.

I have had a similar problem, where the battery LED lights up, then shuts off, but I could not 'power-on' the unit using the on/off button on the front. I measured the battery voltage, and was reading 4V, so that appeared ok, as says 3.7V on its label, However, even with the battery removed, the i600 would still not power on using either its integrated button, or by using the remote control.
I plugged the battery back in, and all is ok!
The battery is accessed by removing just two screws with a cross head, and pulling its cover off. Soi appears that simply removing the battery from its connection, and plugging it in again has cured the prob?
Give it a go, if you haven't already? My unit has been solid/robust/reliable and gets a lot of use and travel, and was gutted that it could need completely replacing.

SOURCE: poor FM reception with Altec Lansing IM600 when using ac adapter

Just wonderin with my Im600 whether to leave in wall socket power. Or is it better to just use up the battery then recharge when I need to.
Also If I use the wall charger plugged in permanently Is it better to take Battery out???

I could not open mine either, very frustrating. I finally jammed some screwdrivers in and pried it open, with considerable effort. The front and back are connected, open simultaneously. The only latch I see is front and center. My suggestion is you get something razor thin and stick in straight through the front center (directly below the LCD display)... that might undo the latch and release the door.

There is a button on the front of the unit that is just below the LCD readout that shows FM / iPod status. Press the button. If it does not open the unit, you may need to tap the back of the unit when doing this or else get something to gently pry open the unfolding section WHILE THE BUTTON IS PRESSED (otherwise you'll break the mechanism and won't be able to lock it again. It sounds like whatever you put in to create the connection may be jamming up your opening.
The unit comes with several adapters for different iPod models, you may want to try a different adapter; you shouldn't need to put anything else in it to maintain a connection. If you don't have those adapters anymore, you can probably get them off the altec lansing web site.
