7 beep at startup
it is actually a "beep-beep-beep-beep-beep-beep-beep" code, 7 beeps. no start screen nothing
theo, seven beeps usually indicates a processor problem. It is very seldom that the processor actually fails, it is most likely a motherboard issue. We may get more specific if you let us know which Dell you have.
See if you can perform a Pre Boot System Assessment (PSA Diagnostic) by holding the “Fn” while rebooting the system. Keep holding "Fn” key until the diagnostic gets initiated. Here are the details on that
You can also try this.
1. Remove main battery.
2. The rear plate for the system is held on by 6 screws. Remove all 6 screws and remove the plate.
3. With the battery compartment nearest to you in the top left corner you will see the CMOS battery.
4. Using a minimal amount of force and a flat tool, pry the battery gently from its seat (it is held on by sticky substance).
5. Unplug the battery from the motherboard by disconnecting the white connector.
6. Wait for two to five minutes and then reattach the battery cable and reseat the battery.
7. Replace the rear plate and the retaining screws and reseat the main battery.
8. Attach the AC adapter and power on the system.
9. If a 5 beep code is heard, switch off the system and restart it.
10. When the system restarts and completes POST successfully, browse to the Drivers and Download page
11. Download and install the latest BIOS Version. from here
If none of that works, you may be looking at a new motherboard. Hope this helps, good luck. from here
I found an American webpage telling how to solve this within half an hour. At first I thought is was mad. I was desperate so I tried it.
With the laptop on and beeping away wrap it up tightly in a large towel and place under the duvet. Leave it for 1/2 hour and then unwrap and switch off. Leave it to cool down and then switch on. I writing this on a dell laptop that had the 7 beeps and the above treatment.
Use a heat Gun cover yout motherboard with aluminum foil execpt GPU.
Heat GPU upto 200c for 7 to 9 minute.Aftet that let board cool slowly.
This will defenetly gonna work
I have a Dell Inspiron M5010. I had the 7-beep cycle error like others. I tried the blanket wrapped tightly while laptop on for 10 minutes, allowed to cool--no change; then went another 15 minutes, allowed to cool--no change again--still the cycling 7 beeps!
So then I followed the advice of another post: Simply held the Fn key down while pressing the ON/OFF button, and BOOM--it immediately went into the blue Pre-boot System Assessment Build 4127. I hit escape to abort testing; the laptop rebooted; took a while to reboot this time, though, and it finally works fine now!
It's likely that on your motherboard your IGP (Integrated Graphics Chipset) has likely failed and is no longer communicating with the CPU/Processor on the motherboard. To repair the issue you really need to replace the chipset with a new one.
I have written more information about this issue on my website here
My daughters inspirion had the same problem. It's either the video chip or the processor. In my case it's the chip. Thermal expansion and contraction made hairline fractures under the BGA (ball grid array) chip. Since we needed her laptop Pronto, I put one squeeze clamp on each corner of the bottom bezel (where the keyboard is). Gently squeezed them so they just start to bend the plastic . This creates enough pressure to make a connection under the chip. Wala, ours worked. Hope this is helpful to you since this is a common problem.
I had this problem and its totally fixed now. Googled all over and couldn't find the answer, but I finally got it and I just wanted to come back and share it for the next guy. There's a guy (it's not me) on ebay selling a kit titled "Dell M5030 Motherboard GPU Copper Shim Thermal Pad - Prevent 7 Beep Overheat" and it actually works. If you're afraid to take it apart, this might not be for you, but if you're comfortable getting inside it, here it is. It was only about 6 bucks and everything you need is provided (except the cleaner).
The instructions provided were a bit unclear, but I did figure it out. You have to remove the heatsink and clean off all the old thermal grease (CRC QD Electronic Cleaner works good for this - I buy it from Advance Discount Auto Parts, a couple q-tips may be needed too, as the old grease gets a bit baked on, so you might need to rub a little to get it clean) Then you remove the stock thermal pads. Stick the thermal putty on your CPU and the other 2 chips that were under the heatsink. Then you stick the copper pads to the heatsink where it covers those 2 chips with the new thermal grease. I did this fix and I've been going about 6 weeks strong with no issues and no sign that there ever was a problem.
Hope this helps some of you all out. It worked great for me. Blessings...
Thanks for these tips. I fixed my daughter's Inspiron 5552 based on info from here. It's currently running a video as a test to confirm it's good (for now).
I happen to have a hot air solder station and I heated the CPU/GPU to 391 degrees F for about 7 minutes, shielding the remainder of the mobo (sort of) using aluminum foil as suggested. I cut a small square of copper sheet from some I had around, tapped it flat with a hammer, sanded it and used some quality thermal paste on top of the CPU. I placed the copper square on top of that, more thermal grease and then replaced the really sh*tty heatsink fan POS back in place. I did spring up the 'tabs' to provide a bit more tension, hoping the combo of fixes will sink enough heat away to prevent the CPU from overheating and re-breaking the solder connections. I can't believe just how crappy the heat sinking is for this. I'm surprised the CPU just doesn't thermal out.
Time will tell.
Its LCD cable not detected. Pressing fn+power to switch on works. Permanent solution is to replace lcd flex cable.
Dell inspiron n5010
I replaced my motherboard and it works like a charm. Right now I am answering your post with this laptop. I put new heat sync also. There is heat sync in Ebay that will correct the 7 beep for $7.00 but since the motherboard is only $30.00 Then I replaced it too.
The motherboard for my Dell Inspiron 15 5558 is $150 (not including sales tax and shipping). I'm sending it out for reflow or reball
I sent my board out for a reflow or repair, it is the power IC chip not the GPU.
Actually these days when that beep sound I'll just push power botten to power off and power on after 2 seconds, mostly it works for me repeatedly. Alternatively when it dint work I allow the beep to continue until I can hear the Fan starting then I'll push power botten off then on again.
