I've got an Acer Aspire 8935g. I attempted to update the bios. Whilst doing so, the laptop crashed and I had to switch it off. Upon trying to switch it back on, it powers up for less than a second (lights up etc) before powering back down. I have been told that I need to replace the cmos battery, but I have no idea if the batteries are specific to a motherboard type/brand, etc, or where to buy one either way.
In essence, I just need to know what cmos battery to buy, and where I may find one for sale.
I doubt it will solve your problem but all you need to do is open the system to expose the battery and read the number. The ones I've seen are ordinary batteries.
Yeah, I'm starting to think it may not solve the problem. I've managed to get the laptop to power up and stay on... but there is no response from the screen or speakers. I've checked the screen/speaker connections and they seem to be properly connected. I can see the GPU spinning, and the hard drive gets hot after a little while, which suggests to me it is doing something. Does anyone know if a failed flash of the bios could permanently damage the motherboard? And if so, would the system still power up? Like I said, the GPU and HDD have power and seem to function... there is just no response from the screen. Is there any way I can test if it is in fact the motherboard that is dead?
