Use the I2C communication tool to send commands to the BQ27541, but this PMIC does not respond normally, and all sent back are invalid data. The circuit should be connected correctly, the power supply uses a DC source, and the load uses a programmable analog load. The slave address...
So far on my laptop I've been using battery saver mode to save as much power as I can while my laptop is unplugged so it can use the battery up to 40% before I charge it at home to save the battery life span. I've also already disabled background apps from running.
However, this will...
I had to force shutdown my laptop recently due to a no boot device screen, and started my computer up a little bit too fast. I know I likely had an HDD issue during this time, but somewhere near logging into windows my HDD makes a single distinct mechanical noise and it worries me.
I've got some strange power issues on my Lenovo Thinkpad 13 (Type 20GJ).
Initially I found the laptop would not recognize the AC adapter (no "Plugged in, not charging" - just would not recognize being plugged in or charge). I solved this by disconnecting the battery (internal), doing a...

I got old Lenovo T410s laptop which had very weak battery but I didn't care since I was always running on power adapter.

It contains additional battery in extension bay (i.e. CD bay).
I have a HP Omen 17-an109nm laptop.
Its battery broke, new one arrived yesterday.
The problem with it is that it doesn't want to charge.
I'm working on it for 22 hours now. I tried EVERYTHING.
It's not a charger issue, not a hardware issue, its something about the software.
My battery seems to have issues with charging. Most times, my computer tells me it's plugged in but never actually charges. Whenever it does start charging, it's random. When plugged in, BatteryInfoView shows me that the charge/discharge rate is 0.
The charger itself is fine because I...
My Alienware 15 R3's battery capacity has dropped a lot and I have owned it for about 2 years
I started out with about 99WH and now I have about 71WH.
Is this normal or is something wrong with the computer.
Usually, the battery lasted for about 4 hours, but now it lasts for about 1 and a...
I got this new HP Envy laptop a few weeks ago, and since then it hasn't been showing me the battery time remaining when I hover my mouse over it, just shows percentage left. Is there any way to change that?
I ordered a battery for a computer and it arrived and what it does is that whenever I have it in without the power supply, it seems like the computer doesn't pull enough electricity because basically the computer is really slow with the battery in. Then the computer starts crashing.
