Hi, I have a E51 phone. The problem is that the notification  light will not stop blinking as long as the phone is on, even if there is no sim inside and the notification light blinking is disabled. It blinks at iregular but very short intervals. Has someone encoutered this problem before? 

Thank you very much.

Update: it keeps blinking while the phone is switched off too until I take the battery off. After that if I put it back it won't start blinking until i switch it on.

Thanks.

try removing battery for ten minutes

this light is also known as a breathing light

you can turn this off

Notification light

You can set the notification light on the cover of your device

to blink when you have received a new message or when you

have missed a phone call.

To set the length of time you want the notification light to

blink, select Notification light > Blink light for.

Thank you veru much for your answer.

The notification light is turned off and I tried removing the battery for 10 minutes but it is still blinking.  This is quite annoying because the battery lasts for less than a day.

do a back up and either update your firmware or reinstall current one

Already tried that

try this then post by rad 24

1. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for ALL operations listed here is 12345

2. *#7370# - Reformat your phone (out of the box, tho keep in mind that most newer nokia phones at least n series, e series and s60 based phones have udp - user data preservation so not ALL data may be lost. still it is a good idea to always do a back up of your stuff.)

3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
hard reset - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons
