Thanks for the reply. I did a bit more scrapping and found points on the board for the battery. I soldered jumper wires to the points and got the laptop to boot and retain the bios settings after a battery pull. -

Dell 15 5566 RTC battery alternate connection
The RTC battery broke off and carried the pads with it. I tried soldering the battery to some points I found after scrapping the board with no joy.
Is there another area on the board where I can solder the battery maybe with jumper wires?

Re: Toshiba C655 not seeing HDD or ODD
Thanks for the response. I removed the board from the case and found a burnt component marked 23AHCP (red line), similar to another component on the board (yellow line). I am not sure what this component is and how it works; maybe i can get one from another board to replace it.
Thanks....Leave a comment:

Toshiba C655 not seeing HDD or ODD
I have a Toshiba C655 that boots fine except it tries to boot via ethernet. The DVD rom light turns orange but does not open and the hard drive does not spin up. Checking the BIOS shows that neither the HDD nor ODD is being seen. Any insight as to what the issue is would be appreciated. -
Re: Acer E5-571 RTC battery - alternate solder point
I followed m1ch43lzm suggestions and ended up soldering the battery as shown, and the settings are now being saved. Using what m1ch43lzm suggested I couldn't understand why I was getting a voltage at the yellow line close to the resistors but not where I had originally soldered the + end of the battery so I scrapped a little more and got a voltage. Not sure if there was a break along the line somewhere but now with the battery soldered, I get a voltage (about 2.67v) to D23.

Re: Acer E5-571 RTC battery - alternate solder point
Should I just try soldering the original battery to the board as suggested earlier; will it cause any issues with the board and will it charge?

Re: Acer E5-571 RTC battery - alternate solder point
The original battery is very small,as seen in the motherboard pics posted (badly solder battery). There is nothing on the other side of the board that would lead me to believe it fits a 2032 battery... I can rig up a 2032 battery to fit but not sure what issues might arise from installing a battery that doesn't, like the original, charge.

Re: Acer E5-571 RTC battery - alternate solder point
Maybe the 2032 image space allows you to install a regular 2032 battery and remove the rechargable original battery? I get a continuity reading from the adapter power lead to the minus lead of the 2032 image space, nothing to the plus side....Leave a comment:

Re: Acer E5-571 RTC battery - alternate solder point
Thanks,
Here are the results,
1- got a 2.07 reading with battery detached from the board.
2- when battery connected, there is no continuity to D23 at least not from the battery lead but from the plus side of the 2032 battery image.
Don't understand, the original battery was soldered exactly where the new one is soldered but I get no reading once attached to the board. Should I solder the battery to the plus and minus (2032 battery image) as you suggested even though it is not the original location...Leave a comment:

Re: Acer E5-571 RTC battery - alternate solder point
Thanks,
This motherboard battery is actually rechargeable (ML1220 Rechargeable Coin Cell... go figure). I am guessing the motherboard keeps it charged once on power or on battery but this is the first time I've dealt with a laptop with this type of battery although it appears to be common. I was wondering if there is some way to know if the cell was providing power to the motherboard once there is no power or, if it is actually being charged once on power; also I can't seem to measure the voltage of the battery once connected...Leave a comment:

Re: Acer E5-571 RTC battery - alternate solder point
Thanks for the quick response. I've uploaded two pictures of the motherboard battery area (ignore my bad solder work), I hope one of them will provide you with what you asked for.
Thank you....Leave a comment:

Acer E5-571 RTC battery - alternate solder point
I have an Acer E15 (E5-571) that is loosing all settings whenever unplugged. I got a replacement battery however the original battery broke off from the motherboard and the positive lead broke away completely. I tried scrapping the board and soldering the new battery to it however it still looses all settings when unplugged. Is there an alternate point on the board where I can solder the positive lead of the battery? I found schematics of the board on the forums however I have no clue how to read it.
Thanks. -
Re: New Members - please post your introductions here
Hey, I found this site a few years ago a when trying to replace my first motherboard CAPS but never thought it had this much to offer. I was looking for motherboard schematics and ended up right back here. The site is full of helpful post and has a wide skill set of users, keep up the good work!Leave a comment:
