After the dust cleared I used an iron file that was about the exact width I needed and just slowly went back and forth about 50 times until I saw the metal and then used sandpaper the rest of the way.

Even its successor DS is pretty hard to get and darn expensive. It sets too fast!

My old computer has been out of action for months, but this week I got it going again by following the instructions on your webpage “Reworking the DS RTC chip”.

The 0V-reading tells you that you successfully disconnected the battery. All described modifictions apply to this chip as well. The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC.

Care for the polarity! Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. A couple weeks ago when I finally got around to hooking it up Don’t ever solder directly on a coin-style Li-Cell.

Note the battery holder! Can you imagine my amazement and relief when I discovered your web site describing the DS rework process. Should work like a charm. Here Best Regards Emmanuel. Datawheet could not have gotten my Compaq DeskPro e back to clock life back without you! There are no provisions for one.

On March, 23rd, Chris xrisl [at] yahoo. Without that webpage, I would never have thought of repairing it like that!

The only things you need to dataheet is: Worked like a charm and would like to thank you and I am very grateful I stumbled on your web site. These are intended for short-term use with strong charge and discharge intervals – not for long-term storage with a comparatively small discharge rate. At that point you wish you could add an external battery.

I appreciate it greatly. Then the battery and xtal are placed atop of the chip, connected to the pins and everything is datasueet with a pretty rigid protective compound.

A really new, fresh and unused chip is hard to get. Then circumstances kept me from working with it until now Go with the hot glue. I just want to tell you that I succesfully used your DS rework How-to. I soldered a 22 solid wire to each of the battery holder pins, then glued the holder to the DS case using model airplane plastic cement.

If you have a multimeter test the voltage on pins 16 and 20 before and after.

Soldered and used a CR battery with holder on top of the I used a medium sized flat file You can see the result here sorry, the text is in french: On January, 7th, Emmanuel Da Piedade emmanuel. Possible Results Reworked chip inside a Mod.

Now the battery is dead, configuration is lost after relatively short time again and you get error-codes constantly. Thank you very much for putting this mod on your web site. William Walsh did the DS-Rework to get an external battery to it as well.

Most likely you won’t get a wire soldered properly to it. Have a datassheet at the graphics below. So you have my thanks and gratitude for putting that idea on the web.

It works like a champ! Don’t use rechargeable batteries.
