Try upgrading your power supply, if you're burning through them then theres a good chance that your power demand is higher then the cords are rated for. Replacing a power supply is quite simple as long as you ground yourself to something metal to make sure you don't manage to accidentally discharge static into your mobo. Also make sure that you're at least somewhat comfortable performing this task if not then id personally advise that you find someone who will

Need drivers to run windows 98se on dell xps m140


Microsoft (and Dell) stopped supporting Windows 98 a few years ago -- it lasted for over TEN years! So, it is *NOT* likely that you will find drivers for any computer that was "designed for Windows 2000" or "designed for Windows XP" or "designed for Vista".

So, in general, it is a _bad_ idea to connect any computer running Windows 98 to the Internet -- Microsoft has issued many "security-fixes" in the 4 years after they stopped supporting Windows 98 and Windows ME.

DELL XPS M140


One of three things, 1- power supply, check your power supply with an ohm meter to see f it's getting the proper output to the machine. If the supply is starving the machine of power the charging system won't work to it's full potential. 2- the power management system on the motherboard, if this system isn't working properly it can divert power from the charging system. If it's just glitched then a bios download or chipset utility download will fix it, if it's malfunctioning, then motherboard replacement is the only option. 3- the battery itself, I have a Dell, and in the past two years, I've ordered two new batteries. The first held a great charge, more than three hours, but only lasted about eight months. The second only holds little more than an hour charge, but has lasted well. Batteries are just funny that way. Start with the power supply test.

DELL XPS M140 POWER ISSUE


Hi brendanram!

I am claudus_07 and i was a Dell - XPS Technical Support Specialist before so i will be glad to assist you with your concern.

As you said into your post, you tried plugging the AC Adapter to the power source without plugging the other end into the XPS laptop and the Green Light on the adapter is lit. But when you plug the jack on the laptop, the Green light is out. As for my experience on your laptop, there could be a problem with the power supply or the motherboard of your XPS laptop. Because everytime you plug the adapter to the laptop, the green light is going out so it means that the laptop or the adapter is grounded.

Here's what you need you to:

Step 1: Call Dell XPS Technical Support 1-800-624-9896
Step 2: Tell them the issue and the things that youve done.
Step 3: At the end of the troubleshooting, i know that the Technician will either replace the Power Supply, Motherboard, or the Adapter. (if you have a friend that has a Adapter same as yours, you may try to use it just to isolate the issue the Technician will choose from the Power Supply or the motherboard)
Step 4: If the Technician replaces the power supply and the issue still persists, call technical support again and ask them to replace the motherboard, no need to repeat the troubleshooting steps anymore just tell them that youre already done with it. (Dont ask for a system exchange, because i know that they will not give what you want.)
