Question about Motherboards
The laptop was working fine till yesterday and when i turned it on today - dead. The battery was not keeping charge lately. However I used to power it up on the power supply and leave the battery in place. I checked the charger and it is giving out the right voltage. Do you think that it is the motherboard?
You could well be wright but concidering what you have said about the battery I would try a few things first.
Clean the battery contacts both on the battery and laptop first with Braso or Autosol and then with metholated spirits. Check that the contacts on the laptop side aren't twisted or depresed. Go into a shop and ask wether you can just try a replacement battery instore with the intention to purchase if it works.
Lithium Ion batteries whilst superior to most other rechargeables in power to weight are inferior in life span. If you get 2 years out a Li-ion your doing well, every day after that is a blessing from God. In most laptops the battery acts as a sink/capacitor/regulator ie battery failure = no function.
Hope I'm rite.
