Question about Dell Inspiron 2650 Notebook

1 Answer

No display My friend's laptop doesn't seem to work, so she enlisted my help. When you turn it on, the fan runs for a couple seconds, then stops. The green power light is lit, but the screen remains black as night. Once, I got it to boot to the Windows login screen, and then the machine froze. I hooked up an external monitor and played with the "CRT/LCD" selector, but still nothing. I've reseated the DIMM card on the bottom (not the one under the keyboard), the hard drive, the connectors for the display and the keyboard, all to no avail. Any other thoughts? Should I go after the internal RAM under the keyboard (I read that it can be tricksy)?

    I found the internal RAM under the keyboard, and re-seated it. Still nothing. The screen is completely blank. If the hard-drive was dead, I would still get some kind of display from the BIOS, correct? And if the LCD was dead, I would think I would still get a signal to an external monitor. If one/both of the DIMM cards died, could that possibly produce these lifeless symptoms?

    I swapped DIMM A and DIMM B, since both cards were identical, and I got some action out of the machine, but it's still very intermittent. It actually booted up completely once, but then froze up a minute later, and wouldn't boot again. I think you're right, the motherboard seems to be cooked. Thank-you for your help nonetheless.

Try the RAM under the keyboard. Try reseating it. Have you added any additional hardware or installed any other software lately?

Do you know how to boot into safe mode? Try that... (Press F8 at boot-up. In the list of options, select Safe Mode or Safe Mode with Networking).

Please update me of your progress.

    If there is something wrong with the board, then these symptoms are also triggered. I had a laptop once that would power on but there would be no display. When troubleshooting the problem with the manufacturer, the resolution was to replace the system board (mother board).

    Sorry :(

you should probably get a new screen fixed to laptop, because until u log in and system boots up properly, second screen will not work,
as u tried turning of laptop forcefully, advance boot options must be up on computer, hence not displaying.

Power on with fan running fast for 3 seconds, then slowed down but no display and no operation


Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you.

After turning on my my acer 2300 its boots up fine but the fan only works for a few seconds then stops and then does not work at all


Normally if the fan is bad and failing the laptop will run hot (overheat) and shut down. If yours is not doing that, then you are fine. Sometimes the fans will turn on and off as needed.

I have a compaq c60 laptop. a couple days ago the laptop would turn itself off and when i would to reboot it, it would only last a couple of seconds. i noticed its really hot right above and below the fan...


Hello, well, if the fan is stalled, then it really needs to be replaced as it will still be consuming power and getting HOT...which is really not good for a laptop as there is little natural air flow within the case anyway. Actually, I've seen those sort of laptrays with a built-in fan, and I think they're a really good thing to have, bearing in mind if you're running the laptop on battery then it'll drain the battery quicker! But have one IN ADDITION to a normall fully-functioning laptop, not as a substitute for a failed internal fan. I advise get that fan replaced asap before you cook something vital (and expensive) in the laptop. Kind regards, nicam49

Since friend un blocked nail,fan wont stop running and wont fire.


somehow the safety switches have become jammed. I would suggest taking the front cylinder off again and checking the o ring at the top where the fan is for being pinched and then without the front cylinder cycle the unit. BE CAREFUL with the fan, insert the battery and push on the trigger switch, fan should come on and go off after a couple seconds. Then towards the top you will see a roller type switch, depress (watch for fan blades) and again fan should come on and go off after a couple seconds. For the final test depress and HOLD the roller switch and then engage the trigger and you should see fire, try this a couple times, if all works then check the lower probe for free movement (depress probe a couple times and watch the combustion chamber for movement to the top) relube the o ring and be careful not to pinch when reassembling. It sounds compllicated but it is really quite simple. Let me know if you need more help

Would suggest booting your system in Safe Mode and running anti-spyware (SpyBot) and anti-malware (Malwarebytes) software. Hope this helps.

CPU fan operates but laptop otherwise dead ?


Remove the battery and plug in the power adapter. Attempt to power on the laptop. If nothing happens, then try holding the power cord, at the jack, at a different angle. Wiggle it a little and see if the laptop will come on. If it does come on, then wiggle it some more and see if the laptop cuts off.

This will determine if your DC Jack is faulty. I have resoldered a bunch of these on this model. Usually the solder around the HOT pin on the mainboard cracks. Thus, you don't get a good power connection.

Now, as far as the laptop coming on with the battery.... how long will it run on just the battery? A couple seconds? Or a couple minutes? Or until you turn it off? If the battery were about dead, then it would come on for just a couple seconds but not POST. Meaning no video or anything. But if it comes on and runs for several minutes without turning off, then a weak battery isn't the problem. It should still POST and show video and all that.

So, even if you get the DC Jack fixed, assuming its faulty, this may or may not solve your POST problem. Never know really until the dc jack is for sure supplying good steady power.

Noisey fridge/faulty fan


Hi Fat head; the problem is not completly uncommon. what can happen is the fan gets something on it and becomes unballanced. Thi in turn wears the fans motor bushings out, and eventually ruins the unit. A couple hundred quid seems a bit steep to me, But I live in the U.S.A., and unless I am mistaken, the cost to have a repair person come, and do a service on an electrical appliance, is considerably higher in the U.K. So no, a couple hundred quid is not completly out of line.
