Some thoughts. First, you may just need to let the NiCd charge for a but. Second, check the protect switch on the bottom of the laptop. If you do need to replace it, here is the battery you need. https://www.ebay.com/itm/3-6V-14h-6mA-Rechargable-Battery-2x-Cells-Ni-Cd-60mAh/352134687427<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ebay.com%2Fitm%2F3-6V-14h-6mA-Rechargable-Battery-2x-Cells-Ni-Cd-60mAh%2F352134687427&data=02%7C01%7C%7C1f2a2743a8f64d1de0f508d5a63bb96e%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636597697793510295&sdata=xBoAdXlNAsjkSzuGuKBB5PXL%2FZQUNP23aPLid%2FzGA5s%3D&reserved=0> I'm not sure I would recommend the seller since I ordered these about a month ago and sadly they have not arrived from China yet. But it's the right type of battery. Kurt On Thu, Apr 19, 2018, at 2:12 PM, David Laffineuse wrote: My M100 came in today and I love it. For now I have it running on 4 AA but if I turn it off, it loses the files that I created. Is it becomes the onboard battery is dead? What replacement should I get? Sent from my iPhone
