My Lenovo laptop is plugged in but not charging. What could be the reason?
I have also faced this problem with my Dell Laptop. I have done a lots of research that time to overcome with this problem. First check that if the plugging wire is loose or not. If it is tightly connected then check whether the Laptop is getting charged with another charger/adaptor. This may be the problem of Adaptor of Charger also. If the Laptop is getting charged properly with other charger. Then replace your charger. Otherwise there may be problem in the software. Please check whether the BIOS is fully updated or not. If the BIOS is updated then do one thing I am telling the STEPs note it down:-NOTE: Don’t Uninstall BATTERY ADAPTAR uninstall CONTROL BATTERY METHODDon’t worry about that. It’s just a controller problem. Try Uninstalling the “Microsoft ACPI-Compliant Control Battery Method” in the Device Manger ->Batteries. If the Battery section is not seen in the Device Manager do the following: Control Panel-> Power Options and CHOOSE the POWER SAVER MODE and Check the Batteries section will appear in Device Manager. Plugged the charging cable into the Laptop and then Uninstall it. After that don’t shut down the Laptop remove the Battery directly. After 1–2 mint. insert the battery again. And in the device manager click the “Action” and Select the “Scan for Hardware Change” and See the PROBLEM HAS BEEN RESOLVED. If not Try RESTARTING THE LAPTOP it will GUARANTEE solved the problem if u have not problem in your wire or Battery.

Is it possible to turn on a laptop camera without turning on the indicator light?
The LED light is supposed to be wired such that if the camera is enabled it should light. However that doesn’t appear to always be the case. It is possible to hack the firmware inside the webcam as well as the driver to turn on the camera without the LED indicator light. So yes, if your computer is hacked it is possible for the webcam to be enabled without the LED lighting. It cannot be remotely enabled without your computer first being infected by malware and controlled by hackers.Apparently, US government intelligence workers cover their webcams with green tape on non-classified computers when not in use. So what’s good for them is good for you. The color of the tape is not relevant.There are nicer solutions to tape such as a super thin stick on frame with a sliding panel. If it’s an external webcam, just unplug it.
Why there is a extra hole near a laptop camera?
Thanks for the A2A.The extra hole is for the microphone which helps you in your video calls. A camera is good enough for clicking still photos if you want but the primary usage of a front laptop camera is to facilitate video calls. That microphone captures your sound and the camera does it's usual job of recording your activities.Hope that answers your question. :)
My laptop turns on but the screen is black. What do I do to fix it?
Other answers have jumped to a hardware fault. Perhaps not incorrectly, sure. But I'd first make sure we're not dealing with a software issue, or any other "have you tried turning it off and back on again?" sort of things.First, and foremost, does your laptop have a "Display Off" button? I have a Sony Vaio which has one of these. It's a flush bezel button near the clamshell hinge. I have absolutely no fucking clue why it's there. But it is. The only thing I can think of is it's a "privacy" button...for when you can't quite hit the (x) close button on the browser window when your spouse walks in on you ogling (.)'s.Since you didn't post a picture I will assume that you mean the screen is entirely black. No faint glow, no nothing? In other words, it doesn't look even remotely like this [note the blinking cursor]:Have you plugged anything new into your laptop recently? A new USB device? A new external drive? Do you have a docking station? If you have a docking station, does it behave differently if on or off of it?Have you verified that your battery is charged, and that even if not, your power supply is providing proper charging to the battery when it's plugged in? My laptop has a little lightning-bolt LED that indicates the power supply is properly plugged in. Sometimes those stupid connectors can become loose -- or worse, crimped [kids knocking the thing about, etc.] -- so that they don't make a proper connection. I can't tell you how many times I've sat down with my laptop that had been "plugged in" for hours only to hit the power button, see it appear to go through its start-up groans, only to have it fizzle-out and not work shortly after.Do you have a recovery disc for the OS you have installed? What happens if you turn the power on with that in the laptop?Do you have a USB memory stick? If so, there are a bunch of different things to try here Boot and run Linux from a USB flash memory stick, even booting DOS from it.
