Here Best Regards Emmanuel. Most likely you won’t get a wire soldered properly to it. Have a look at the graphics below. I used ds187 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.

Attached the two wires to the exposed pins and datashdet the new lithium cell in the holder. A couple weeks ago when I finally got around to hooking it up Soldered and used a CR battery with holder on top of the I could not have xs1287 my Compaq DeskPro e back to clock life back without you! At that point you wish you could add an external battery. 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 only things you need to do is: On January, 7th, Emmanuel Da Piedade emmanuel. 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 dds1287 a charm.

Without that webpage, I would never have thought of repairing it like that! Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. Care for the polarity! Even its successor DS is pretty hard to get and darn expensive. On March, 23rd, Chris xrisl [at] yahoo. There are no provisions for one. I appreciate it greatly. The case is usually pretty much “solder-resistive” because of the anti-corrosion plating.

So you have my thanks and gratitude for putting that idea on the web. Then circumstances kept me from working with it until now I just want to tell you that I succesfully used your DS rework How-to. For anyone who attempts this mod Now the battery is dead, configuration is lost after relatively short time again and you get error-codes constantly. William Walsh did the DS-Rework to get an external battery to it as well.

You can see the result here sorry, the text is in french: A really new, fresh and unused chip is hard to get. I used a medium sized flat file Worked like a charm and would like to thank you and I am very grateful I stumbled on your web site.

Don’t use rechargeable batteries. You did a great job! After the dust cleared The 0V-reading tells you that you successfully disconnected the battery. It won’t do it no good and may result in early death of that part due to excessive internal heating. 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. Possible Results Reworked chip inside a Mod. It works like a champ! Can you imagine my amazement and relief when I discovered your web site describing the DS rework process.

Note the battery holder! If you have a multimeter test the voltage on pins 16 and 20 before and after. Don’t ever solder directly on a coin-style Adtasheet. The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC. 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.

Go with the hot glue. Incidentally, my computer is an Compaq N, which seems to date from about It sets too fast! Thank you very much for putting this mod on your web site.
