On January, 7th, Emmanuel Da Piedade emmanuel.
The only things you need to do is: Curiosity killed that cat. Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. You can see the result here sorry, the text is in french: 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 datasheett storage with a comparatively small discharge rate. After the dust cleared I appreciate it greatly.
You did a great job! I discovered that the RTC chip was dead. Can you imagine my amazement and relief when I discovered your web site describing the DS rework process. Here Best Regards Emmanuel. I used a medium sized flat file It won’t do it no good and may result in early death of that part due to excessive internal heating.

I could not have gotten my Compaq DeskPro e back to clock life back without you! Note the battery holder! 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. Should work like a charm. Attached the two wires to the exposed pins and put the new lithium cell in the holder.
Possible Results Reworked chip inside a Mod. Don’t use rechargeable batteries. The 0V-reading tells you that you successfully disconnected the battery. If you have a multimeter test the voltage on pins 16 and 20 before and after. A couple weeks ago when I finally got around to hooking it up It sets too fast! 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.
Without that webpage, I would never have thought of repairing it like that! William Walsh did the DS-Rework to get an external battery to it as well. Then circumstances kept me from working with it until now 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”.
Now the battery is dead, configuration is lost after relatively short time again and you get error-codes constantly.

On March, 23rd, Chris xrisl [at] yahoo. Care for the polarity! All described modifictions apply to this chip as datashewt. A really new, fresh and unused chip is hard to get. Incidentally, my computer is an Compaq N, which seems to date from about Go with the hot glue. Soldered and used a CR battery with holder on top of the It works like a champ!

Don’t ever solder directly on a coin-style Li-Cell. For anyone who attempts this mod The daily self-discharge rate on some rechargeables is higher than the current taken darasheet the RTC.
Even its successor DS is pretty hard to get and darn expensive. So you have my thanks and gratitude for putting that idea on the web.
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. At that point you wish you could add an external battery.
Thank you very much for putting this mod on your web site.
Have a look at the graphics below. The case is usually pretty much “solder-resistive” because of the anti-corrosion plating. Most likely you ds2187 get a wire soldered properly to it.
I just want to tell you that I succesfully used your DS rework How-to. There are no provisions for one.
