I used a medium sized flat file Thank you very much for putting this mod on your web site. Most likely you won’t get a wire soldered properly to it. I just want to tell you that I succesfully used your DS rework How-to. The daily self-discharge rate on some rechargeables datsheet higher than the current taken by the RTC.

Can you imagine my amazement and relief when I discovered your web site describing the DS rework process. Soldered and used a CR battery with holder on top of the Then the battery and xtal are placed atop of the chip, connected to the pins and everything is covered with a pretty rigid protective compound.

Possible Results Reworked chip inside a Mod. 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. Don’t use rechargeable batteries. I discovered that the RTC chip was dead. These are intended for short-term use with strong charge and discharge intervals – not for long-term storage with a comparatively small discharge rate.

All described modifictions apply to this chip as well. My old computer has been out of action for months, but this week Dtasheet got it going again by following the instructions on your webpage “Reworking the DS RTC chip”.

A really new, fresh and unused chip is hard to get. Sd1287 Best Regards Emmanuel. You can see the result here sorry, the text is in french: Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. Have a look at the graphics below. Note the battery holder! The case is usually pretty much “solder-resistive” because of the anti-corrosion plating.

Attached the two wires to the exposed pins and put the new lithium cell in the holder. On March, 23rd, Chris xrisl [at] yahoo.

William Walsh did the DS-Rework to get an external battery to it as well. I could not have gotten my Compaq DeskPro e back to clock life back without you! dataseet

For anyone who attempts this mod Worked like a charm and would like to thank you and I am very grateful I stumbled on your web site. A couple weeks ago when I finally got around to hooking it up Curiosity killed that cat.


You did a great job! Incidentally, my computer is an Compaq N, which seems to date from about It sets too fast! There are no provisions for one. Then circumstances kept me from working with it until now 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.

The only things you need to do is: Without that webpage, I would never have thought of repairing it like that! Should work like a charm. Don’t ever solder directly on a coin-style Li-Cell. At that point you wish you could add an external battery. I appreciate it greatly. Go with the hot glue. Now the battery is dead, configuration is lost after relatively short time again and you get error-codes constantly.

Even its successor DS is pretty hard to get and darn expensive. It works like a champ! The 0V-reading tells you that you successfully disconnected the battery. So you have my thanks and gratitude for putting that idea on the web.
