No Win7, no exchange battery

Inexpensive does not always have to be bad, but here unfortunately. Spoiled housing, large but poor keyboard, wherein some keys simply stand out. Lousy 3-cell battery, which holds by just 90 minutes. And then the battery can not be changed because it is firmly installed. So back in order, and wait for a new one. If I had not have done, because the new one has the same lousy quality. And who will win 8 7downgraden to Win .......... not going.
