QUESTION I can’t charge the battery in my Dell laptop unless I first remove it and blow on it. Replacing the original battery hasn’t fixed the problem. Andrew Pullen

HELPROOM ANSWER Replacement batteries aren’t always built to a high standard. If you didn’t buy a Dell-branded replacement, this could be the problem. However, it’s more likely that the charging components are failing. Take the laptop to a local PC repair shop and ask them to order suitable replacement parts.
