Not to use it as a typewriter. Although keyboard has been replaced and newest Bios has been deployed: Stay away from Proxdukt. How can you create a notebook that sell for huge money and not make sure that you can at least write it? Have bought this a wireless keyboard and mouse, and lo and behold: for not even 40 euros is the thing to use. But rather Manufacturer: I have so much money spent to sch ... a small notebook to have, and when you have taken 40 euros more and for a keyboard that works: I can only give to the following customers: Stay away from this product. This is my experience- perhaps others have made a different experience, but I have no product with which it could live not for the price! Thank you: Never again
