For some laptops (I know of some Samsung) you can't fix errors or it won't boot, so you need to use older version or run IASL from command line (it will create AML even if there are errors).
You may also have made some mistake, like saving DSL (source) instead of AML (binary).
Just extract and compile (fixing errors or not) won't make a difference. If you don't make any changes, it's the same as if you don't have a dsdt.aml at all.
