UPDATE: Wake On Lan setup has locked the laptop.
FIXED IT!
Removed both batteries, run on line power, started right up. Killed the 'Wake On Magic Packet Only" setting, and it runs fine again. I think Andy Burns wins the internet for suggesting that (may have missed someone else suggesting that) Big thanks to all of you for the suggestions. |

At least one design, it was on the bottom side of the PCB.

But dead reconning like that is only possible with really good photos. Many laptop CMOS batteries are on a twisted pair "tether". And the battery is covered in shrink wrap, so it cannot short to anything. You buy a whole new assembly, rather than trying to "recycle" the welded assembly in front of you. http://t0.gstatic.com/images?q=tbn:A...jBP_wnb3tNL2v0 The connector should be keyed, but take note of which lead is red and which black, when removing the old one. So you don't reverse it by accident. Or perhaps buy a design that isn't wired right or something. There are two kinds of coin cell for this. CR2032 is not rechargeable. It last three years. The LR2032 is rechargeable, using energy from the main battery for recharge. It might last several days with the main battery removed. Always match "like with like". If you find an LR2032, replace with an LR2032. Paul |

Luckily, they don't know that their CR2032 CMOS batteries should only last 3 years. ;-) snip They last three years... if you pull the main battery pack. They last ten+ years, if you leave the main battery pack in place. Now, the interesting part for me, is how do they avoid rapidly discharging the main battery pack, to keep the CMOS and RTC running. To avoid draining the CR2032, there has to be a circuit regulating down from 14.4V (battery pack voltage) to the 3VSB voltage used to keep the RTC running. It's dead easy to make an inefficient circuit, but if you did that, the laptop battery could be "ruined" by self-discharge below threshold. And then the charger won't touch it. I don't know exactly how they convert the 14.4V laptop battery voltage, to 3VSB @ 10uA, and do it while drawing no more than 10uA (or so). Many three terminal regulators "leak" a couple milliamps while doing absolutely nothing, so the obvious answer isn't the right answer. On a desktop, they can afford such a wasteful practice, because the AC mains are very obliging. ******* The same rules apply to a desktop PC. The CR2032 lasts for three years, if you leave an unplugged PC in your junk room. Whereas you get ten+ years for the CR2032, if the ATX PSU is plugged in and switched on at the back. The best for this, is probably the Macintosh desktop approach, where they stick a largish $12 to $15 battery in the thing, that can last at least ten years while the machine is unplugged. The battery finally died on my G4 (which is unplugged all the time), and the shocker for me is that it still boots. The time-of-day isn't correct, but it rectifies that eventually using NTP. Paul |

It took some prising apart after spotting it's the type where you need to lift the keyboard out. I found the CMOS battery is the ML2016 rechargeable type with welded on tabs; de-soldering it made no difference to the laptop booting, so it's now declared junk. |
