Lenovo R400 Error 0210 stuck key 5b


Stuck key error means that one or more keys on the keyboard are stuck. It's possible that a liquid spill can also cause one or more keys to electrically "short" causing the error. Inspect the keyboard and check if any keys are mechanically stuck.
If you're mechanically handy you can remove the keyboard, inspect any chances of damage or corrosion. Plug it back and see if error is still occurring.
Reset BIOS to default settings. Perform Flee Power - remove the battery and any other peripheral device connected to the computer. Hold the power button for 10-15 seconds and then connect only the AC Adapter and turn ON the computer.

My lenovo G550 appears not to charge when the charger is plugged in despite turning the mains power on and off to see if power is getting though and the blue neon light showing on the mains...


Hi m529,

I see you are having issues with you G550 charging.

You mentioned that the light on the charger is lit up but then it suddenly switches Off, and you also mentioned that the charge still has a light but the power is somewhat low despite of a fully lit up charger Light.

Have you tried draining the power from the system?

  • Remove the battery and the Charger or AC Adapter as well call it from the G550 then press and hold down the power button for 10-15 seconds to drain power from the system motherboard.
  • Once drained connect the AC adapter but do not connect the battery yet, then turn the Laptop ON to see if the system will power ON using the AC adapter/Charger if it powers up then there is no problem with the AC adapter/charger.
  • After testing the AC adapter if it is working power down the Laptop doing a normal shut down.
  • Once shut down or turned Off insert the Battery back in the Laptop then turn the Laptop ON using the battery only without the AC adapter/charger see if the system will turn ON using the Battery only.
  • If the Laptop powers On using the battery alone with out the AC adapter then the battery is most likely working as well on the issue.
  • Now power down the Laptop then connect the AC adapter to the Laptop with the Battery in the Laptop as well then turn the system ON again see if the problem will Occur again having the battery and the AC adapter/charger if the Problem happens with both Battery and AC adapter on the Laptop then the problem is the Motherboard, most probably the motherboard is having issues relaying power from the AC adapter to the battery and may be sent to the Depot for repairs.
I suggest that you call Lenovo for further information about your system, if you still have warranty and is still in the one year period then your system will be covered for any repairs needed - you can call @ 1 877 453 6686 for troubleshooting, you will be asked for a serial number Located underneath the Laptop on a small white sticker that states s/n meaning serial number.

I hope that this Helps.

Have a nice day,

My lenovo ideapad y560's monitor won't open. the monitor is pitched black.


Hi thelzy,

I see that your Lenovo Y560 is having issues showing no Video, you mentioned that you only get a Black screen when booting.

I am assuming that there is still power on the machine but no video at all, Just to ask do you still see the Lenovo Splash screen? if not then we can try doing a power cycle on the machine.

* Remove the battery on the system unhook the Power Cord/AC adapter as well then press and hold down the power button of your Y560 Laptop for about 15 seconds then let go.

*After Doing the Power Cycle connect the AC Adapter again but leave the battery out for the time being then turn the compute ON, check to see if it will show the Lenovo Splash screen if it does then we're in progress and should show windows Loading up on the LCD screen.

*If it does not show the lenovo Splash screen then most probably the BIOS screen never showed as well on the issue.

*Connect the battery back n the machne turn it ON again check if it will show anything on the screen, if not then see below.

*We can try connecting an external mnitor to the system using a VGA connection it should show us the Screen on the external monitor if not then it means that Windows as well is not booting on your Laptop.

*Check the indicator Lights on the Laptop, one of the Lights will be a cylinder icon on the Laptop check if there is any activity from that light if there is no Light or any avtivity to any of the indicator lights then your Y560 is having issue with the Motherboard.

I hope this info Helps.

Have a nice day.

My hp 2100 presario laptop in not booting


Startup problems
If the notebook doesn’t respond when you turn it on
• Connect the AC adapter.
• Reset the notebook by inserting the tip of a paper clip into the reset button on the
bottom of the notebook. Then press the power button to turn it on.
• If the notebook still doesn’t respond, remove the battery and AC adapter, remove
any PC cards, and undock the notebook if docked. Then plug in the AC adapter
again, and reset the notebook using the reset button.
If the notebook won’t boot from battery power
• Make sure the battery is properly inserted and fully charged. Check the battery
charge by removing it and pressing the pad on the side of the battery. The lights
show the charge level.
• If available, try another battery.
If the notebook won’t boot from the floppy disk drive
• Make sure the floppy disk drive is selected as the boot device.
• If you’re using a USB floppy drive, use the BIOS Setup utility to make sure
Legacy USB Support is enabled. If your notebook also has a built-in floppy
drive, use the BIOS Setup utility Boot menu to make sure the USB floppy drive
is the first device under Removable Drive.
If the notebook stops responding after booting
Check whether you are connected to a TCP/IP network with no DHCP server. This
can cause a long delay at startup because DHCP is enabled. Contact your network
administrator to determine the proper TCP/IP configuration

***IF THE NOTEBOOK HAS POWER BUT WONT BOOT INTO OPERATING SYSTEM-
Press F2 when you start it to enter BIOS to check your BOOT ORDER to make sure your HD is listed first on the list.
If it is not listed remove it and reinsert it and then try again.. GREAT LUCK!! Please Rate Me, K? Thanks- Lucky4lynn2

E6500 making a beeping noise


Does beeping noise happened before turning on laptop? If yes unplug the laptop from the AC Adapter. Just leave AC Adapter ON and connected to the power outlet. Check if AC Adapter is the one making beeping noise. Note: This is an issue with dell AC Adapter laptops
If no beeping noise in AC Adapter then proceed checking it from the laptop. Does beeping noise happened immediately when laptop is turned on? If yes then it might be laptop's hard drive creating the sound. Try to check the BIOS in your laptop under the category performance if the HDD Acoustic is ON either in Normal or Performance. Note: When laptop is in performance the hard drive makes noise due to its speed, this is normal if BIOS HDD Acoustic mode is ON to performance.
If the noise only happens when sometime while working on the laptop, this might be cause by the laptop fan. This also happens after turning on the laptop fan my have dirt and dust, please do check.
If fan was cleaned, HDD performance was checked and AC adapter was checked then, carefully sense if noise is coming from the internal speakers.
Download the latest BIOS update for your laptop then flash the BIOS. Make sure battery and AC adapter are connected when doing these.
