A BIOS/CMOS battery is a wear part! (rant) [pictures ≈ 300KB]

Dear manufacturers I have big news for you: Batteries don’t last forever. This is nobody’s fault. But it is a fact. Sooner or later any battery will be drained. This is also true for low-power devices like clocks and SRAM. A CR2032 will last some years. After this it has to be replaced.

Why do I have to disassemble a complete laptop just to get to the BIOS battery? What were they thinking?! No, I will not throw away a working computer because of a dead BIOS battery! Thank you for the “TERRA MOBILE 2103 – MODEL M66SE”!

I just unscrewed a million screws, disconnected a bunch of ribbon and antenna cables just to reach the battery. And guess what I found?

I can’t help myself but to think about the little Brothers Grimm fairytale: The Wishing-Table, the Gold-Ass, and the Cudgel in the Sack. [Wikipedia]

I don’t have one of these batteries with cable and plug. Last time I met one of these I cut off the cables and soldered them to a CR2032 battery holder, wrapped everything in insulating tape and put it back into the laptop. Works. Hope I can fit a battery holder into this machine as well. Then to reassemble this piece of sh electronics…


Edit:
The computer is working again. Not enough space to put a battery holder for CR2032 there. I used CR2032 for SNES games to solder the cables on the tabs and wrapped this into insulating tape. Looks almost like before.

Thing is we dont really don't know what breakthrough could be just around the corner. Computers (as we know it ) are still relatively new in terms of technology and we still have long way to go before have a foolproof system (if ever). Helium drives should have never made it to the consumer level. Their main uses are for Enterprise/server uses where heat production is a big problem and drive life anyway is much shorter than the consumer model.

If we are to believe what's said in the media then in the next 10 - 20 years computers are gonna drastically change from what people are used to today with the introduction of quantum computers ( if that ever really gets off the ground ) or something else. If you went back in time to 1992 and told me that in 20 years you would be able to have a computer that fits in your pocket and had access to the sum of all human knowledge i would have looked up and screamed at the top of my lungs " stranger danger!! stranger danger!! " lol or if we are being serious for a second " that sounds cool but i don't really see that happening "

We have gone from hard drives the size of washing machines that could store a matter of megabytes to having 1Tb that can happily sit on my finger in 60 years.
