Interesting battery problem

I have a Dell Inspiron E1505 from a couple years ago and I am having an interesting problem with it.

First, I will give a bit of background information

The laptop would run extremely slow whenever the battery was in the laptop. Even when the laptop was running on AC power, the computer would run extremely slow as long as the battery was in its compartment. The only thing that would get the laptop to function correctly with the battery in it was to put the battery in the freezer for a little while.

I considered the possibility that the problem might be with software, such as Dell's OEM installation of XP Pro or some sort of driver being used, so I did a reinstallation of the operating system with a retail XP Pro disc.

The fresh installation seemed to solve the problem completely for a while. However, the computer is starting to run a bit slow again when it has the battery in it. It isn't nearly as bad as it was before, but the difference is still noticeable.

I know this laptop model had a battery recall, but the serial number in my laptop isn't one of the recalled batteries.

I don't think it is an overheating issue. The problem persists after the laptop has been turned off for extended periods of time, such as days.

The strangest part to me is that the laptop doesn't have to be running on battery power for it to be slow.

My theory is that it is either a bad battery or a poorly designed laptop.

Does anyone have any guesses?

Thanks!

 

Well, I have the E1505, and I have not had any of those problems in the 15 months or so I have had it.
I think your battery has an internal short in it, which is causing the system to not run properly. Or the charging circuit on your system may be screwed up, making it think the battery is in all of the time, making it run slow.

Download cpu rightmark, and go into the battery tab.
It will tell you if your battery is working properly. Also take note if their is any wear on the battery.
My battery is made by SMP, and its the 6 cell one, and I havent had any problems.

It seems like your problem is either battery related or a complete coincidence.
Your system may be running slow because of a slow harddrive, or a background process which is eating up your cpu, memory and harddrive cycles.
To shut off the background processes, go to the start menu, go to the run command and type in MSCONFIG. In their, go to the startup and application tabs. Than shut off any processes, services, applications and so forth which you are not using. Than reboot, and see if the problem has gone away.
Also open up task manager, and look to see if their is a certain app which is using all of your cpu power, cause that may be your problem.

If your worried about overheating, download i8kfangui, by Christian Diefer. It is fan control software, which can control the fan for the processor an graphics card.

I am with K-T on this. I think batt is fried? Run benches with batt in and out to confirm it is really happening.

Also have you played with you power profile settings to see if you can override?

 

I would recommend to take out the battery and run on the AC only. If you feel it run faster without battery. Then please try to run some 3-D mark software to confirm did it run faster.

If my assumption is right, it is possible the system is running a battery mode when the system detect a battery. A battery mode will reduce the speed of some components for a longer battery life. However, this problem shall not exist when you are using AC adapter and battery together. If you confirm the system is running faster when the battery is detached, you shall call Dell support and tell them the problem.
