Please forgive this post if it's been asked before. I searched the site but couldn't find the answer.
I have a Dell Studio XPS 1647 that suddenly won't turn on. When I first press the power button I get a dark LCD screen and 6 beeps followed by a pause, then 5 beeps. I believe this is a beep code 65? I can't find what this means anywhere on the site. Any information as to what this means is greatly appreciated.
I also noticed the CPU fan does not power up. I have replaced the fan with a new one and had disconnected all the power including the BIOS battery for over several days while the new fan was shipped. It still gives me the same beep code.
The beeps codes does not indicate any error. This system has LED indicators. which are the mute, volume up and volume down buttons. They would flash a sequence to indicate a point of failure. Please observe and share the sequence (example mute button flashing, volume down button solid and and volume up button solid).
I would suggest you to run the Dell Diagnostics (if possible) to check the hardware functionality. Power off the computer -> restart the computer, press 'F12' key on the Dell logo -> Select ‘Diagnostics’ from the boot menu.
Beep Code Possible Problem
One Possible system board failure — BIOS ROM check-sum failure
Two No RAM detected
NOTE: If you installed or replaced the memory module,
ensure that the memory module is seated properly.
Three Possible system board failure — Chipset error
Four RAM read/write failure
Five Real Time Clock failure
Six Video card or chip failure (Actually 7 beeps is more common)
Seven Processor failure (GPU Is unsoldered) Reflow Fixes this.
Eight Display failure (LCD Cable or Display is broken)
Hi and thanks for the quick replies. I appreciate it greatly.
No error codes on the LEDs. They light up like normal when the system worked. I can even press each button and they light up and dim like they did when the system worked fine. However the screen never lights up so I can't access Dell Diagnostics and the CPU fan (now replaced with a new one) never spins up. Also the hard drive never loads.
It seems to me the system is not passing a BIOS check. I cleared the BIOS by pulling the battery and leaving it out for several days.
I also experimented with the RAM by removing one module, then the other and attempting to boot. No luck. I get the same beep code regardless so I don't think it's a RAM issue.
Is there any documentation as to what a beep code 6-5 is on an XPS Studio 16 (1647)?
Finding a document for the beeps codes may not be possible as the beep code does not indicate any error for this specific model.
Let's test the LCD of the computer for functionality.
Run the LCD BIST. To run the LCD BIST (Built in Self-test):
Yes Appu, the LCD did light up and showed the series of colors as you indicated. At the end of the test I heard the beeps again and then the system still didn't POST. The LEDs on the control panel lit up but didn't flash any kind of error either.
The beeps could be due to any stuck key on the keyboard. I would suggest you to carefully check the keys on the keyboard for any stuck keys. Also, try to re-seat the keyboard and the LCD cable. You might also want to re-seat the RAM and check. Here is the Service Manual http://bit.ly/10TlJxu. Please ensure to follow safety instructions.
Hello, I am experiencing the exact same problem you described and am very curious if you ever found a solution. The LCD test worked the same also. I will probably open it up at some point and see if something came unattached, as we did have a repair done recently.
Thanks for any information.
Unfortunately I never was able to fix the laptop so it wound up getting scrapped. I apologize for not posting a final result here. I know from personal experience that its tough to find a solution when people only post their problems and fail to follow up.
Are you a certified DELL technician or what? By saying that "beep codes does not indicate any error" just proved you do not know anything about computers. Beep codes are there to diagnose problems before the computer boots up, but these codes are limited to memory errors, and other hardware malfunction before the operating system could be loaded to RAM. And NO, you can't run Dell diagnostics if your computer doesn't even turn on. And YES, I am a COMPTIA A+ certified PC technician.
