Issue as described above. Here is some more detailed information: My brother bought a Acer Laptop about a 1 1/2 ago from tiger direct retail store. After about 6-7 months the laptop would not hold a charge or charge at all/power on (sporadically it would charge and work fine for a few hours then go back to not charging). I believe this may be due to the fact that he would use it heavily (probably between 6-12 hours at a time) with the bottom of the laptop laying on a pillow or flat surface with little to no adequate ventilation. I tested the power supply with a multimeter and it appears to be working. My question is: what is the most likely part/component of the laptop that needs to be replaced given the way he used or abused it, and can I test it with a multimeter to confirm faulty component? Thanks in advance to anyone with a constructive answer and I would be more than happy to provide more information for anyone that is willing to help me solve the issue.
