Problem with Dell Inspiron 1100 series laptop

My laptop seem to be functioning okay although the fan was cutting on more frequently. My problem is that it will not boot, it will appear to switch on and power up but never get to the boot window screen and just turns itself off after about 5 seconds. Would the fan not working cause the system to shut down for saftey reasons? I received no errors prior to it not working, just shut it down after use. I pulled the whole system apart, down to the fan, and cleaned everything. Monitor is working. Thank you for any help, Lee

Most certainly a non working fan would cause this behavior. Laptops are much more susceptible to overheating. Fan failures can be hastened by regularly blocking the fan by doing things like using it on a pillow or soft surface. The behavior is exactly what you think.

Re: Problem with Dell Inspiron 1100 series laptop

Try unplugging your laptop and letting it site for an hour. If your laptop refuses to boot after it has been off for more than an hour I would doubt its the fan because an unmodified Dell laptop with a failed fan will not overheat that fast unless something major is wrong. Even if it detects a failed component (fan) it should display an error during the early part of the boot cycle. No video during the early boot phase is not typically a good sign, but I would also check to make sure the unit is getting power, LEDs are deceptive. The best way is to check the battery to see if it is fully charged. Dells have the ability to switch from the laptop LCD screen being active, to just the VGA connector on the back or both. If you have a working monitor around try plugging that in and starting up again. If you don't get anything try toggling which display is active. The typical Dell has a key in the lower left hand corner labeled "Fn" (function) in blue ink. Look for another key labeled "CRT/LCD" also in blue ink and typically is the "F8" key. Hold the FN button down and hit the CRT/LCD key once. If nothing happens try it again after 10 seconds, and again after another 10. The first click is to change from the LCD being active to CRT, the second changes from CRT active to both, the third goes back to LCD only again. If none of this works you are probably looking at a major repair, video controller circuitry is on the motherboard?..

Dell 1545 inspirion labtop bios pass word code

The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard.

Another way is to reset the clear CMOS jumper on the motherboard itself.

Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip.

So by cutting off the battery power, the BIOS/CMOS settings will be erased. cmos battery Under the keyboard or bottom of laptop -

If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

or you might give them a call

Dell Inspiron BIOS Password Recovery

Each Dell Inspiron has a master password that clears the BIOS password. Call Dell Technical Support at (800)624-9896 to get this number.

Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Inspiron.

If the current user is not the original Inspiron owner, Dell will transfer the used Inspiron's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

To transfer a used Dell Inspiron's registration, fill out the Transfer of Ownership form on Dell's web

hope this helps

Will the Dell Inspiron B 130 work without a battery, but with a cord?

Any laptop should run with a cord (that is functioning properly) whether there is a battery installed or not. Have you checked the charger to verify that it is putting out the proper amperage?

My laptop,dell inspiron 600m, got no sound,when i try to play audio it seems playing but no sound out,the same to video. I went to control panel all drivers are functioning properly.

I'd try 3 things first:

  1. Examine the laptop closely to see if there are any "wheels" close to the audio ports, not all laptops have 'em but if yours does try adjusting that "wheel"
  2. Uninstall all of the audio drivers in the device manager and reboot the computer.
  3. Check Dell's support page for your model and download the latest audio drivers for your system.
Let me know if what happens.
