I have already written and submitted 26 pages of my thesis in Word, and used the font Cambria, 12pt, double spaced, with 1 inch margins on all four sides. The document also has a header and footnotes.
You need reformat the document with AOO, and it is better to save it into the native international Standard ODF file format. Use the Styles (paragraph style, page style, frame style, character style, etc...) instead of the direct formatting.
There is not 100% compatibility betwenn the different file formats: never was and never will be. The AOO always works in the ODF file format when you edit a foreign file format document, and you will lost some format property at all of conversions: at opening conversion and at the saving conversion.
Other possible issue: do you have Cambria font on the new laptop? The AOO will substitute the missing Fonts with a similar font (but it will not same size and shape precisely.) As I know it, the Cambria font is a part of the MS Office suite, then maybe you have not a license to install it onto the new laptop separately. Use the really free and/or opensource font families, like the DejaVu, Liberation, Linux Libertin, etc... Everybody can install them without any restriction.
