IBM Think-Pad X60 Upgrade Log

These day, I tried to upgrade second-hand X60 IBM Think-pad.

It is a really old model (Intel Core 2 Duo ), but still good to use.

It has facing several problems and I am trying to use minimum cost (maybe) to increase the user experience :P

Vector, Beware of erase()

If you are using this style and when you erase() items in vector, be careful dont perform ++iterator.
Since the pointer to the item that you erase(), it already release, so the pointer target will become unknown,
and causing undefined behaviour if the iteration keep going.
It is possible cause the vector iteration out-of-bound.

template <class T>
void Container<T>::removeValue(T *value, bool deletePointer)
{
	for (iterator i = values.begin(); i != values.end(); ) {
