There simply will not be enough power to run your laptop.
When using a power ibm thinkpad r50 ac adapter, most importantly, remember to use the power adapter only with the laptop it is intended for. All computer manufacturers develop different power adapters specially designed for their line of products. Some companies, like Apple or IBM, make one type of power adapter that works with all of their laptop models. Never experiment with combinations of computers and power adapters that are not approved by the manufacturer.
