Problem is that when connected to the power adapter the LED comes on indicating that it is plugged to the mains and with the battery put in the battery LED light also comes on but as soon as I press the power switch to turn on the laptop, the lights all go off. Please I will like to know if you guys can suggest a solution to this.
There are only a few things that can be done 'economically'.
1. Remove the Battery and boot only off the A/C Adapter ; bad battery
2. Try replacement RAM IF only (1) stick <and/or> swap (1) stick per boot ; bad RAM
-- Requires opening the case:
3. Disconnect the HDD and boot in to BIOS ; chances are bad HDD
4. Disconnect Battery, A/C Adapter, and disconnect CMOS Battery 10 minutes ; corrupted BIOS
IF the above fails to identify the problem replacing the MOBO, CPU or Display is cost prohibitive; new Notebook.
Unlike a Desktop, Notebook parts & labor cost exceeds on a the replacement cost.
