I have had my aspire laptop for about 3 years with no problems.Now when I try to start up the power light flashes for about 10 minutes.After this the light comes on fully and the laptop boots.I have read several posts from people that have the light flashing 5 times,but mine continues for much longer than this.I have folowed the advise about disconnecting the battery but still have the problem.The battery is holding its charge and once the laptop boots it works as normal.
