Gs155a mobie cannot power on but while charging handset get on in display batter full

The handset cannot communicate with its base.

When the handset cannot establish its secure (encrypted) radio
link with the base it is 'paired with' or 'registered' to, it will first
say "Connecting....", then it will display "Out of Range or No
Power at Base", then it settles at the infamous "Searching..."
display.

Although rare, the registration between base and handset can
become corrupted and lost so that we must de-register and
then re-register the pair.

First, ensure that power is 'on' at the base (a more common cause)
and the cradle will charge the handset, etc.

Second, be sure the handset battery is well charged as a weak battery will interfere with the registration process.

Then try the following ( 'works for the D1680, D1481, and similar):

To deregister the handset:

1. Press and hold the [END] and [ # ] keys at the same time,
after a few seconds the display will say
"System Reset, Deregister Handset"
press [SELECT]
scroll to "Base Unavailable"
press [SELECT] (chirps) press [END]
display reads "Place in base..."

Next, to re-register the handset:

2. Set the handset into the base cradle and wait,
after ~30 seconds the handset should display
"Handset #" and be good to go...
or it will display "Registration Failed"

Good luck!

if its straight out the box, you should charge the new handset at least for a 12 hr period, (overnight) & your handset will do one of two things, stay turned on & display full battery strength,or remain off but display battery full on the screen,the longer you keep on charge (max 24hr) the longer the life of your battery.

Shirley, check if you inserted the chip properly. Usually the bars are your wifi strength. Most likely its the chip.

Depending in its age, the battery might just be shot. It may say full charge cause it takes all it can but it might only be a few min worth. Most Mp3 players can be taken apart and the battery replaced.

A few tips: Delete your text messages. Text messages use the phone's cache, deleting them will improve speed.
Let the battery die, and charge back to full. This will clear the phones batter settings. Power the phone off, and let sit for 2 minutes, then power back on.

Hi.. Let me try to help you if I can... I'd like you to check a few things,

1) Open battery cover on handset & make sure that the battery pack is installed correctly, and not upside down. Also make sure the little wires that come from battery pack are plugged into the tiny jacks of the phone (usualy red & black wires) in handset is fully attached & pushed snuggly into the handset... and if No wires, check to ensure the part that does connect the battery to handset is not covered with a plastic film of tape or paper as right from a manufacturer they sometimes do that to preserve length of battery until product is sold to you..

2) Check the bottom of the handset phone, that sit in the cradle of the electric part of the recharger, and make sure there is nothing like plastic or paper covering the connections between the bottom of the handset and the charger. Make sure there is a full on connection for a full charge to the handset. As with some cordelss phones Ive had the red LED light will not come on if there is something blocking a full connection for a charge.. The red LED light on base, only comes on when the electricity is flowing into the handset. The slightest tilt not allowing handset a full charge, wont give it a FULL charge.

3) You say " NEW. Out Of The Box" I hope when you connected the battery pack into the handset, and made sure it was connected right, you then allowed handset to charge at least a FULL 12 -24 hours before trying to use your new cordless phone. as the batteries right out of the box, are rarely already fully charged when any cordless phone is bought and then it does need 12 - 24 hours for a FIRST FULL CHARGE...

If you can check all 3 of these questions, and let me know how things are back on this posting, if you stilll can not solve the problem after a full charge to battery, I may have some other ideas that can help.

Good Luck

Try to reset the handset from handset menu, maybe the eeprom setting for low battery warning threshold have been ereased . Also check ,if the battery is the oregional battery for the phone.

Presume you are talking about the extra handset. Try placing the extra handset in the "main" base for 5 seconds.

USer manual requires,
full charge 16 hours for expandable handsets, then place in cradle ~20 seconds until 'ready' is displayed on the screen.
If power is lost the handset may have to be re-registered.

if the units are not fully charged when you register them the registration may be lost, can only suggest reversing the order, by fully charging the device then registering to see if the registration holds
