OP let us know if you're able to recover your ETH and if not take your time to remember the things you did when you've bought ETH.
Sorry in advance, this sounds really funny when you forget to buy where the site, exchanger or wallet is. just try searching your laptop's histroy. how to click in the upper right corner of your browser, then search for crypto-related history. then match the password or private key that you have.
It's possible that OP used a browser that doesn't save his browsing history and sometimes you could forget things when you're very busy.
If it's only a password then I think you could work something out. First is are you getting a feeling that you make the wallet on myetherwallet? What apps are you using currently and what wallet have you used before? Did you get the private key, keystone, or the 12 word seed?
With just a password its unlikely since he still need the file if it's through MEW.
