Question about Dell Inspiron 1100 Notebook

1 Answer

I need help with power problem

The power on my laptop goes off and on constantly. When no power is going through the laptop the screen gets a little dark and it lights back up when there is power. The AC adapter is fine. This has been going on for months now. Also, the light on front of the laptop the third light it blinks orange about 5 times then it blinks green once. This also has been going on for a long time now. Is there a solution to this because my pc cuts off a few minutes later when there's no power going through. I think it's the power socket on the back of the laptop where you plug in the AC adapter. I think it's loose or something because I can sort of move it while the plug is in.

You are correct about the DC plug on the 1100, they are well known for the problem you posted. It could be one of two things, the solder points where the DC jack is soldered to the motherboard could have "cold solder joints" and re flowing the solder will fix it. Or the DC jack itself is faulty (the more common issue with these Inspirons) in which case almost all PC service shops will insist that the Mother Board has to be replaced (Not worth replacing), but you can obtain the jack for a reasonable fee and either replace it yourself (if you are very good at desodering and soldering, It's surface mounted, and not through hole which through hole is a lot easier to do), or open the laptop remove the Mother Board and take it in to a reputable electronics shop and have them use their state of the art equipment to replace the faulty jack for a reasonable fee.
Good luck.

My dell laptop keeps going back and forth from the loading logo screen to black screen


You might like to Power it off completely by removing the Battery for a few seconds.
If that doesn't help, try booting from your Win7 Installation Disk.

This indicates a motherboard issue, sub out the ram memory one at a time, test each as you go, if no change! The motherboard will need to be replaced, or the laptop.

Battary is not chage its not working


What happens on almost all laptops is that either a: the solder breaks from the constant wiggling of the power plug in the socket causing the socket to become loose and not get a good connection, or b: the power supply module (the little box thing attached to the cord ) goes out, usually because people leave their laptop plugged in all the time, and it was never designed for long term constant use
The cord is only meant for charging the battery, or as a temporary power aupply in the event your battery should give out on you.

I have a compaq v2401 cl, screen is turning black but when i pressed the lid button it turns back on for a while and after that goes back off.need help. thanks


This is likely an issue with power management- are you using the computer when the screen goes black? Or does it happen if you step away from the system...? If this is the case, go to control panel > power options and adjust the delay for your LCD turning off. If the situation is where the screen turns off constantly, that is an issue w/in the hardware of the laptop, and requires you to contact either HP or a local IT firm like Geeksquad or others for repairs to your laptop.

After password wlecome then blue screen,need to hole power to do anything


Dear, you system's start up files are infected or disturbed. There is one way that can help.

1. start the system.
2. constantly press and release the F8 button to get system options and select the safe mode for start up.
3. if it starts up properly into the window, just restart your system.

if not then you need to re-install the operating system on your system, becuase such problems often occur due to the worms and virsus, and it may harm you further.

Best regards.

Laptop's light is turning off!


This is going to be a problem with either the screen inverter, or the screen backlight. I would recommend have it diagnosed first to see which it is. You can test this yourself if you have an ohm meter, and a little technical know how.You will need to pull the screen bezel (the plastic piece around the front of the screen), the are screws hidden under the small round plastic sticky tabs on the bezel. Once you've removed the screws the bezel will snap off. Get it started at one side and work it up the rest of the way around, be careful not to break it ar the corners when lifting it off. Once the bezel is off you will see the inverter at the base of the screen. Power down the machine and disconnect the lead that goes to the screen. The power going into the inverter is very low, the inverter boosts the power back up to what the screen needs to work, so the power on the screen end will be significantly higher than the motherboard end. The voltage range differs machine to machine, so I can't tell you what it should be exactly, only that if it's the same or slightly higher from end to end, then it's bad. Now, inverters can be changed out, but backlight are part of the screen and cannot be change out. If it's a bad backlight, then the entire screen will need replaced.

The fan kicks in because your processors temperature gets above a threshold, and this usually happens when your computer is under heavy load. And when your computer is under heavy load, the computer will most likely be a little slow. Thus the fan speed can only help your computer; you don't want to change anything there.
I'm a little perplexed about your mouse problem, post back with more details.
