In addition to that, all computers that sit idle for years need to have the cmos battery replaced. That keeps the bios info while the computer is not plugged into an outlet. It dies when it is never plugged into power or after 5 or so years. Try replacing that and then try connecting the adapter. Bios coin cell batteries are a couple of dollars in any store. Look up your manual for instructions on replacing it and what model battery to buy. Newer laptops can work using just the adapter after the dead main battery is removed. Worth a try.
The blinking light means it is not completely dead.

If you buy a new car and park it in a garage for 3 years, then go to start it up -- it won't; the battery will be dead, likely permanently.
All batteries begin aging when they're manufactured. The general lifespan of a Li-poly battery is 300-500 charge cycles or about 2 years.
It's not abnormal to need a replacement battery particularly if the battery sat unused for a significant length of time.
