Since it sounds like an issue with the Power first try to release flea power.Disconnect the charger,remove battery,press and hold down the power button for 30 seconds.Reconnect the battery and charger.Turn on system and check if it turns on. For further help please check Dell Inspiron 1525 Manual. Also confirm if the light on the charger stays on,when connected to the system.
I have sucessfully repaired three I-Inc CY199D monitors which all had the same problem.
The monitors program is stored in a 24LC16B which is a 16K serial EEPROM in a SO8 package.
The bad part is you have to remove this eeprom to program it as it is write protected on the board and you will need a serial EEPROM programmer and an uncorupted program I have all the above.
If there is enough interest I could offer preprogrammed EEPROMS or a repair service for the graphics card..
The problem is the program for the graphics card is stored on a 16K serial eeprom which is used as a rom this can get corrupted which causes the problems you are experiancing.
I have repaired three of these monitors by re-flashing the eeprom with a program cloned from a working monitor all worked fine after refashing.
Now the bad news as the eeprom is used as a rom it is write protected on the board so the only way to program it is to remove it flash it with a valid program and then replace it easy if you are a surface mount expert.and have a serial eeprom programmer.
