Lenovo laptop with terrible beep-sound when power-supply are plugged in- and out
When the power-supply are plugged in- and/or out, my Lenovo laptop 3000 v200 makes this terrible beep-sound. Lenovo support claims that this sound is impossible to remove and that it is supposed to be there, but I then find it strange that nobody but me seems to be complaining about this issue on any computer forum. The sound is present both when running windows and e.g, bios... Any ideas for how to get rid of the noice?

The beeping is a safety feature of a damaged charger so the problem
must be the charger, not the battery. If you happen to have another
charger try using it to see if it fixes the problem. If your warranty is still valid, you could try asking for a replacement. The charger could still work for a while but there is a possibility that it would lower your battery life.
You can purchase a replacement laptop charger from various sources, if
that's what you want to do. Websites such as Newegg, ebay, amazon, google
shopping, and etc. sell laptop chargers
at very cheap prices compared to the original manufacturer. However, you
got to be very careful on exactly what you are buying. Be sure to read
all the warranty, policies, and specifications before purchase...
Whenyou connect the power adapter into the laptop, does the power LED light up? Ifnot then -
The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.
Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.
This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.
The keyboard controller maybe faulty. Connect a PS2 or USB keyboard to see if it functions correctly. If the external keyboard works normally then the laptop keyboard is faulty and can be replaced.
If the external keyboards do not work normally then it is a motherboard problem.
This sounds like an overheating issue. Make sure your vents are free of dust and debri by using a can of compressed air. Then try powering on listening to see if your fan is spinning. If it is not you'll need to replace it. If it is then make sure you are using the laptop on a cool hard surface rather than cloth or such. If you still have the problem then the most inexpensive fix would be to purchase a laptop colling pad to use underneath, usually $20-40 at most computer stores. Hope this helps.
It seems that your laptop is holding webcam loading problems. Check whether the webcam driver is compatible for the OS which you use.
You can also try re-installing the webcam driver once again. This should do.

Looks like you're right, I did not see any Lenovo replacement jacks either. You might try looking at the IBM Thinkpad jacks for various models to see if you can find the same jack.
I've repaired 3 laptops with this problem. Rather than replacing the jack on the mainboard I wired a "pigtail" to the mainboard and then zip tied a female connector to the back of the laptop itself. I did this because the mainboards were pretty beat up from the heat the original jack produced as it began to loosen. The end result is not as pretty as the original jack, but it absolutely takes all the stress off the mainboard. Those computers will never have this problem again.
