Windows 7: New laptop battery messes up date/time, etc...

05 Dec 2009   #11

Windows 7 Ultimate x64

Yeah, I thought that too. But, the motherboard along with the CMOS battery are about 4 months old. I also performed a full diagnostic test with both batteries, and with the AC adapter alone. I found no hardware defects.

I even called Dell, and they had absolutely no advice. Dell technicians kept saying that it was a faulty battery. However, how could it be a faulty battery if it's working on my friend's computer? That's something that's quite intriguing.

That is just baffling since your replacement battery works on another M1330. The CMOS battery was an idea but if the computer keeps its date/time using the OEM battery, then the CMOS battery is probably okay.

Anything else would be grasping at straws, it would seem..... like cleaning all of the battery contact "fingers" (toothbrush??, contact cleaner??) in case the replacement battery isn't hitting all of them (necessary to function properly).

Keep us updated if you find anything.

You said, earlier, that you plugged your battery in to your friend's computer and it worked perfectly. Have you tried his battery in your computer? It seems like that would tell you if it is a battery problem right away. If his battery does not work, then cleaning the contacts sounds like a good idea. Also, if possible, check the contacts for the CMOS battery. The battery may be good, but, not making good contact. Perhaps a piece of fuzz is stuck in there.

This is obviously part of Dells reward scheme, which you get the benefits of - for the manner they judge you've been scrimping on your battery.

Dells are renowned for being built specifically to prevent generic battery usage, the press has been inundated with stories from end-users for the last few years - there have been so many it's kind of hard to imagine any Dell owner could still be in the dark regards the issue.

If you're unhappy with this either buy a genuine Dell battery, or get another brand of portable computer - that's the bottom line.

Lol...yeah it's funny how much you learn about a company AFTER you make a purchase. I wonder which laptop I'm going to buy next...

As for this whole battery mess, it really has baffled me. I spoke with Dell representatives on the phone, and now are sending a technician out to me. However, I honestly doubt the techs will be of any help.

Battery connections are clean, no interruptions with the CMOS battery. As for Dell not allowing the use of non-generic batteries...that would make sense...IF the battery did not also work on my friend's computer. If the battery did NOT work on my friend's laptop, I would've been very happy right now. I'll keep you guys updated as I gather more information.

It's well known that Dell have this policy and make these sorts of implementations to discourage users from buying consumables elsewhere.

Batteries and chargers are singled out.

You won't necesarily reproduce the problems on another machine unless it is identical in hardware, BIOS and Software setup respects.

Did you ever find a solution to this problem? I am having exactly the same problem with an m1330, however it is with a new Dell OEM battery. It's driving me crazy. Was the tech able to help?
