Boot_c_03.05.00r_mpap my q turned off when i had full battery and wont turn on unless it is plugged into the charger. when i get it turned on the screen is back and the message motorola flash mode bootloader version: boot_c_03.05.00r_mpap usb cable connected comes up what can i do

Take out the battery and try with just the charger, Batteries for computers have regulators in them and when the batteries die, the computer wont boot.

juast full out your battery and sd card sim in 1 to 2 seconds and theback it again and press power on and plug ur charger in usb port show it if its is running ur batttery icon located in the upper right side thats all try it now

The battery must have gone bad! if its three or more years old you need to get a new battery for the computer. Periodic conditioning of the battery from first use may prolong the battery life. Battery life is reduced by plugging computer with battery all the time.
Conditioning. Periodic full charge and full discharge practice is good for battery. Batteries are better charged when they are at less than 10% power and its better to charge them to 100%. Do not leave on electric power once they are fully charged.
I hope this helps in future but current battery may need replacement!

Hello,
It may be the battery draining all the current and not allowing the motherboard to receive enough power to boot.
Can you please remove completely the battery and try to boot again?
Please let me know more details and I will guide you to the next step.

Best regards

ur battery is dead

simply change the motherboard it will work good

on the desktop click right button and click properties.now go to the apperance below the windows and buttons chane it as windowsxp style.

Is the voltage meter directly on the Battery?? What model Dell is it?? I have found that on the D800 models for some reason the connection from the power button to the Motherboard comes loose. You need to remove the Keyboard cover to check this.

Sounds like your device is defective and needs to be replaced. Time to look for your warranty info sorry to say

Hi, I would suggest that the Battery is faulty.. a common occurrence I have found... Try a brand new or fresh charged know good battery.. I think ya may find thats the culprit.. Also check & clean the Batt Cons inside the unit.
