    Hello, all 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.

    Hi all, 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. So...

    Howdy, 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...

    Hi all, 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.

It’s not until the end of the commercial that the giant baby turns into a car indicating that his car is his baby...

Some would have flashlights, others could start a car, and there was even a couple that could charge a smartphone seven times over. However, as the reviews continued on, I began to notice that once...

    Is it just me or have smartphones reached their maximum thinness? What else can they do to help cut down on the weight and size of the phone, while still maintaining normal operation? It seems like they may be looking to cut battery life. If you are a Pokémon GO player, have you noticed that...
