SOURCE: Dell Vostro 1000 shut down and won't turn back on

nope, it is your dc power regulator board. you will note this happens if the battery is in or out of the laptop. that is the key test. some regulators are on the main board and some are seperate for this reason. I think the vostro though is on the main board. A little board re-work will resolve this issue after replacing some components, but this is way beyond a home user's ability.. trust me on this. Sorry for the bad news. Thanks!

I don't know if this will work with Vista but in Windows 7 you can go to the speaker icon in the taskbar and click on the icon above the volume control. This will take you to the sound properties. Click the levels tab and mute the PC speaker. This worked for me.

Laptop will not charge battery. Issue with internal power converter, etc.


The motherboard has charging circuits built in to regulate the charge to the main battery, in rare causes it fails leaving a choice to attempt a repair or replace the motherboard. I suspect this is what has happened to your system.

Hi,

Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.

2. Connect the laptop directly to the power outlet without using the battery just for the meantime.

3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.

4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.

Hope this will help...Your response is very much appreciated...

Certain models talk to a chip in the adapter, sounds like this one has gone bad. At this point you can live with, buy a new one or pick up a used. This is a fairly popular model and you should be able to locate one from a dead laptop.

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.

IBM T30 - power issues


You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.
