Question about Dell Computers & Internet

1 Answer

My Dell Inspiron 1520 seems to use a lot of battery power, even when the lid is closed, and nothing is running. Is there any way to save battery power, without going into standby mode, or turning off the hard drives? Thanks...

How long does your battery usually last? If it lasts 2 hours or more, that's normal for a notebook computer. The standby mode and turning off of hard drives is what notebooks are designed to do to give you more battery life. If you have to have it on and available all the time without going into standy mode, you'll need to get used to charging it every couple of hours. If you want to get more battery life, try the following options:
1) have the display turned off when not in use (this setting can be changed where you set up your screensaver)
2) turn off the wireless function (if available) when not in use
3) have the computer go to standby mode after 10 or 15 minutes of inactivity.
4) lower the brightness of your display

All of the above assumes that you're getting a decent charge and can use the notebook unplugged for 2 hours or more. Naturally, over time, notebook batteries wear down and don't hold a charge as well as they once did. If your notebook is a few years old and you're only getting an hour or so on a full battery, then it is probably time to invest in a new battery. If your notebook is new and you are getting this short battery life, contact Dell for a replacement battery as yours may be defective.

One last thing about notebook batteries. They are designed to be charged up and run down. If you leave your computer plugged in to a/c power all the time while you are using your computer, this greatly speeds up the wearing down of the battery. Whenever possible, you should fully charge your battery and then run the battery down to 10% or less before plugging it back in. This ensures that you get the most battery life on a consistent basis.

Hope this help. Please take a moment to rate the solution. Thanks.

Dell inspiron 1520 won't turn on.


Remove the battery from its compartment on the side of your Dell Inspiron laptop computer.


Remove the power adapter from its plug on the side of the Dell Inspiron (if your laptop is currently plugged into a wall outlet).


Press down and hold the "Power" button on the laptop for one to two minutes. This will dispel the excess electrical current that is built up inside the laptop.


Put the battery back inside the compartment of your Dell Inspiron.


Plug your power adapter back into the side of the Dell Inspiron. Press "Power." Your laptop computer will now turn on.


hope this helps

The only for sure way to check really, is to replace each part, one at a time with a known good part. Or an obvious sign like beep codes. And yes, I have noticed the older dells tend to toast motherboards. Could be something to do with power as well, though. Might want to check into that first

I just bought a new Inspiron laptop, as well as a Kensington USB docking station and a Dell WM311 wireless mouse. I can't get the mouse to work at all, and can't get the docking station to work properly...


Closing the lid of most laptops sends a signal to put the machine in hibernate or sleep mode. You can either leave the lid open or change the power savings settings. In Win 7, this is in the Control Panel but can also be reached from the advanced power savings settings from the Screen Saver. Click on the desktop (anywhere without an icon or running program) and select Personalize. Click on the Screen Saver and then Change Power Settings. Then Change Plan Settings (look for the line Advanced Plan Settings and the section marked Power Button and Lid).

I don't know enough to help you with the mouse problem. I'd check the batteries for the mouse first. Then ask Dell.

I wish that I could be of more help.

My screen on my dell inspiron 1520 has gone black


You've lost your desktop display.
The first thing I would do is to start the computer in safe mode. Once there, do a system restore back to the time that it worked.
I would also, just to be safe, do your disk management tasks like checking your hard drive for errors and running defrag.

Dell Inspiron 1300 - When I re-open the lid,Screen stays Black !


Your laptop either goes to hibernate or sleep mode when you close the lid. Then, when you open the lid up, the screen is still off because your pc already hanged/froze and could not wake up at all (usual problem in vista). Off course, hard shutdown would fix it. But actual fix is under power options on your control panel. Check your current scheme and edit it. There are options there that you can select to "do nothing when closing the lid"

Hope this helps

My dell inspiron 1520 has dark screen


If you replaced the backlight and you still have the same problem then the next step you should take is to replace the inverter.

That should solve your problem, if it doesn't let us know.

Closing my laptop's lid crashes the system


Check what video card you have.
  • Go to start. Right click My computer. Click properties>hardware>device manager. Click the plus next to 'Display Adapters'.

Check the video card listed under Display adapters.
  • If you see Intel. Click this.
  • If you see Nvidia. Click this.
Just follow the wizard and restart afterwards.
Try to close the lid again and see if it got fixed.
