Good Day Psmith!

It looks like the AC adaptor is not making the right supply voltage needed for your laptop.

If you have a multi tester, you can test your ac adaptor to see if it has stable 20V voltage output supply needed for the laptop to make it work.

Set your tester to DC range. Plug the ac adaptor to your wall socket. Hold the other end of the ac adaptor (the one you connect to your laptop. Insert the red (positive) lead into the center of the adapter pin, then touch the black (negative) lead to the outside metal part of the pin.

Read the display in your tester. If the adapter is working properly, the meter should read between 19 to 20 volts of the rating. If the adapter is faulty, the meter will read below 18volts.

If that would be the case, I'm afraid you will need to replace your ac adaptor.

You can purchase online a replacement ac adaptor for lenovo 8932.

    Good Day Psmith!

    Thank you for waiting! It took me awhile to respond to your questions.

    Psmith, Please check the settings on the Power Management Properties of your system.


    Power management. To reduce power consumption, the computer has three power management modes: screen blank, standby, and hibernation.

    Screen blank mode If the time set on the "Turn off monitor" timer in the operating system expires, the LCD backlight turns off. To put the computer into screen blank mode, press the ThinkVantage® button and use the ThinkVantage Productivity Center. To end screen blank mode and resume normal operation, press any key.

    Standby mode. To cause the computer to return from standby mode and resume operation, do one of the following:
    - Press the Fn key.
    - Open the LCD cover.
    - Turn on the power switch.

    Hibernation Mode. If you are using the ACPI operating system and have defined one of the following actions as the event that causes the system to go into hibernation mode, perform these actions.
    - Closing the lid.
    - Pressing the power button.
    - Pressing Fn+F4 keys.


    The power management system conserves
    battery power by setting the processor to run at a slower speed,
    dimming the screen, spinning down the hard drive when it's not in use
    and causing the machine to go into sleep mode when inactive.


    Hope this input will help you.
    Thank you for asking Fixya.

My lenovo G460 laptop doesn't turn on ?

Did you have exhausted the battery power? If so, maybe the laptop can't turn on as soon as you plug in the ac adapter, as you can try to let the laptop charged for a time and then turn on the laptop to see if every thing is well.

Toshiba Satellite won't start up when AC plugged in

Try another Cord/Charger to verify the Cord, AC jack. If you plug in the AC cord after starting on battery, does the battery charge? Open Control Panel, Power Options, set to High Performance, Advanced power settings, set Sleep and Hibernate to Never, Adjust Advanced power setting to your preference.

My Screen doesn't work!

Sounds like the monitor went out if the video input is usable with another monitor. If--the screen is dim and not totally out this could be because you are on battery and not plugged in. The only other thing would be that the monitor got unplugged somehow. You may try to look-up how to access this plug (usually under the F Keys).

I hope this helps!

Hi. I have a HP Compaq 6820S, Intel Pentium T7250, 2 Gb RAM, 160 Gb HDD, i have a problem, Laptop won't charge battery. I let the laptop in sleep mode, around 7 days, when i come back, battery was 0%,...

try a new battery yet? (brand new fresh)
sleep mode. so you want it to run for 7 days in sleep.
ive no idea how long this laptop runs in sleep
and hibernate is longer.
no idea at all.
you do know that the speed features are programmable
right?
including what chips do and do not go to sleep'
like USB ports, WIFI, and all wake on , features. like Ethernet chip.
and more.
why not just turn it off, and let the battery last longer..
this mode sleep kills batteries faster. way faster.
leave it plugged in all the time to the wall pack.
so the battery never drains unless you need to use it, on battery.

I got my acer and the power light comes on but the screen is black

This happens with my Acer Laptop too. Make sure the computer is plugged in to a power source and try a forced restart. If that doesn't work, try using the sleep command to but the computer to sleep while the screen is black but the power is on. The computer's power light should shut down, and you should be able to go out of sleep mode by pressing spacebar.

Monitor black out

Someone adjusted the brightness on the system for AC power mode. Turn on the system with the AC power plugged in, hold down the "Fn" key in the lower left of the keyboard, then press the up arrow in the lower right. This will increase the brightness; set it at whatever level looks good to you.

The AC pwoer keeps on and off (most time off) all the time, however, it still can recharge the battery

This is not a good sign!
If all physical connection seems fine, it could mean something is wrong on the power modules of the motherboard! Please try another power adapter to see if it's the power adaptor's fault. If not, get it into lenovo service centre for check-up, as this could damage your laptop motherboard's power modules permanently!
This happened exactly what I had on my good old ASUS laptop, I ended up replace the motherboard. Pay little money to get it serviced before you have to replace the whole motherboard!

Lenovo R61 won't get to login

Hi,
I,d suggest To charge the battery Fully.
Then power up the laptop, with A/C Adaptor connected.
Also check your models user manual, regarding the sleep/hibernate mode. the laptop may have gone into one of these modes. Usually a ( zzz ) Icon Key or Similar.
Also when booting press the LCD/VGA Button.
If all else fails, try to see if your laptop, has a hard-reset button or switch. ** Sometimes this can be a small hole ** On the underside of laptop. *** Only use with laptop Powered Off ***
