K800i wont start

Basically, if the phone does not power, you need to check the status of your battery and charger,also check if the power switch is bouncing,if does not gets back or bouncing, need a replacement indeed.

* By clicking ON the phone,see if there's a red light blinking beside the camera switch.

There are 2 causes of Red blink.

1st, Red blink may cause battery problem,might be lack of supply or drain due to long term used and can't able to power it up. Try to replace another one for a test before buying a new one, to see if only battery is the problem.

2nd, Phone software might be corrupted or damage, base on my costumers cases, many phone encounter full memory, some of them drop or fell on the ground, mis-handling such as removing the battery immediately with out turning off the power switch because they want to replace another simcard,when try to turn it on,no response on the phone. this can not be fix by updating it on the internet or what ever free software maybe,it will not be detected by the computer if the phone is already dead. Possible to fix this problem with the use of gsm gadget and it is available in any mobile service shop near you.

I have 3110 mobile i m havvving charging problem what should i do

try to change your battery, maybe it's worn out. 2nd, maybe your charger is broken. if you have another nokia cellular phone with the same charger, try to charge it up. if it won't charge, then, your charger is damaged. an advice: let your battery be drained before you charge it up so that your battery will last a bit longer than the actual battery life itself and don't overcharge it also. if it is full, unplug your charger always.

I have a dead battery in my lg envy and my charger wont charge my phone but that same charger will charger my sisters phone. How can i get my phone to charge?

try your sisters battery on your mobile. if it powers up and your charger isnt working on your mobile then you have an internal loop fault in the power section of the mobile that directs power to charge the battery. its a big fault and is far cheaper to replace the phone than to have it repaired.

take care.

When I plug my phone in to charge it will not charge, why? It's the Enve2...

Can the phone on when you put it on? If the phone does not on, then maybe the battery cell is weak and cannot come up with a charger expect you charge the battery seperately with a desktop charger and the battery cell should come up by so doing. After which you can start charging.

If that's not the fault, check the charger, maybe it is no more working.

If it is not the charger, then the fault might be from the charging port.

If the fault is not from the charging port, it might be a software problem.

I believe you should find the fault if you follow the steps above. One of them should be the problem.

Best wishes.

Did you replace battery recently? Sounds like it has bad or wrong battery. If not, it is just dead.

To fix:
Power up phone on charger

Leave out for 1/2 to 3hr - phone still plugged in
Replace Battery, phone will power cycle and start charging
Leave plugged into charger 10-14hrs
Should be good now

L7 unable to charge

All cellphone run on Lithium Ion batteries. These batteries, by nature(physics) have a max charged voltage of 3.4 to 4VDC. So, of your charger, or USB cable, has less than about 5 VDC, then either charger is defective, USB cable(if charging from PC USB port) is not a FULL USB(has data leads only wire, 5V power wire not carried through, PC does not supply 5V power to USB because it is turned off by a PC setting option, or a non-powering USB Hub or other device is in series with PC and Phone.

Are you sure you have identified the GND wire correctly? Measurements must all be made with one lead of your VoltMeter referenced to GND. Another consideration, some Windows Mobile phones will not charge off the USB cable unless the latest version of WM ActiveSync or Mobile Device software is loaded and running on the PC. These WM phones also will not charge from just any AC USB generic charger. Charger has to be for that particular phone, or phone manufacture, to be 'recognized' before provideing charge.

May be the phone was water damaged. This kind of problems normally we see in water damaged phones. If not water damaged then PA (Power Amplifier) may be shorted and need to be changed.
