As a solution by anecdote: My (by now) ancient laptop simply won't charge (or boot if cold) if the wattage of the psu is insufficient. This will easily solve that problem as you find out when the battery runs out of juice. I noticed this as it originally came with a 45 watt charger but after a processor upgrade the required power would be at least 60 watt. Note that it will charge the battery when off with any charger, it is just slower.
