A couple weeks ago when I finally got around to hooking it up Should work datasheeg a charm. The 0V-reading tells you that you successfully disconnected the battery.
Even its successor DS is pretty hard to get and darn expensive. You did a great job! I appreciate it greatly. Don’t ever solder directly on a coin-style Li-Cell. 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.
A really new, fresh and unused chip is hard to get. Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC. I discovered that the RTC chip was dead. Incidentally, my computer is an Compaq N, which seems to date from about These are intended for short-term use with strong charge and discharge intervals – not for long-term storage with a comparatively small discharge rate.
After the dust cleared The case is usually pretty much “solder-resistive” because of the anti-corrosion plating.
Now the battery is dead, configuration is lost after relatively short time again and sd1287 get error-codes constantly. At that point you wish you could add an external battery. I used a medium sized flat file Here Best Regards Emmanuel.
If you have a multimeter test the voltage on pins 16 and 20 before and after. Attached the two wires to the exposed pins and put the new lithium cell in the holder. Go with the hot glue.
Curiosity killed that cat. You can see the result here sorry, the text is in french: It won’t do it no good and may result in early death of that part due to excessive internal heating.

For anyone who attempts this mod Possible Results Reworked chip inside a Mod. Worked like a charm and would like to thank you and I am very grateful I stumbled on your web site. Care for the polarity!
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. Most likely you won’t get a wire soldered properly to it. Without that webpage, I would never have thought of repairing it like that!
Note the battery holder! Have a look at the graphics below. I could not have vatasheet my Compaq DeskPro e back to clock life back without you! All described modifictions apply to this chip as dafasheet. Can you imagine my amazement and relief when I discovered your web site describing the DS rework process.
William Walsh did the DS-Rework dayasheet get an external battery to it as well. On March, 23rd, Chris xrisl [at] yahoo. It works like a champ!

I just want to tell you that I succesfully used your DS rework How-to. There are no provisions for one. The only things you need to do is: Soldered and used a CR battery with holder on top of the It sets too fast! So you have my thanks and gratitude for putting that idea on the web. Darasheet January, 7th, Emmanuel Da Piedade emmanuel. Don’t use rechargeable batteries.
