Laptop beeps 7 times


Try link: http://blog.parts-people.com/2014/06/27/dell-inspiron-m501r-m5010-beep-codes-diagnostic-indicators-2/ How to identify beep codes: When a laptop or computer first powers on, it goes through an initial set of diagnostic tests to make sure vital components are preforming correctly. These tests are called POST or Power On Self Test. When a test fails, the user is notified via POST codes, Light codes, or Beep codes. For diagnosing Beep codes you need to:
  • Power on the laptop or restart it if it is already on.
  • Listen to the number of consecutive beeps when the computer begins to boot. Restarting the laptop may be necessary and should not harm the laptop at this time.

Beep Code Explained


Thanks to Transcend Technical Support for this great Brief of understanding beep codes that is found here
This is a long post and it may be truncated at the bottom. If so, use the link above to go to the Transcend web site where these are found




1.General POST (initial system boot) BEEP Codes
If you do not know the BIOS manufacturer, the following will be the general Beep codes:
• 1 Long and 1 Short Beep ?Bad Motherboard
• 1 Short Beep and nothing else happens ?Disk Drive/Video Related Problems
• 1 Long and 2 Short Beeps ?Bad Video Card
• 1 Continuous Beep or Non-stop short Beeps ?Bad Power Supply
• 3 Short Beeps - Bad Memory
2.American Megatrends Inc. (AMI) BEEP Codes
• 1 Beep - Memory refresh timer error.
Reseat the memory, or replace with known good modules.
• 2 Beeps - Parity Error
Reseat the memory, or replace with known good modules.
• 3 Beeps - Main memory read / write test error.
Reseat the memory, or replace with known good modules.
• 4 Beeps - Motherboard timer not operational
• 5 Beeps - Processor Errors
• 6 Beeps - Keyboard controller BAT test error.
• 7 Beeps - General exception error.
• 8 Beeps - Display memory error.
If the system video adapter is an add-in card, replace or reseat the video adapter. If the video adapter is an integrated part of the system board, the board may be faulty.
• 9 Beeps - ROM checksum error
• 10 Beeps - CMOS shutdown register read/write error
• 11 Beeps - Cache Memory Bad

Beeps 4-7, 9-11
Fatal error indicating a serious problem with the system. Consult your system manufacturer.
Before declaring the motherboard beyond all hope, eliminate the possibility of interference by a malfunctioning add-in card. Remove all expansion cards except the video adapter.
?If the beep codes are generated even when all other expansion cards are absent, the motherboard has a serious problem. Consult your system manufacturer.
?If the beep codes are not generated when all other expansion cards are absent, one of the add-in cards is causing the malfunction. Insert the cards back into the system one at a time until the problem happens again. This will reveal the malfunctioning add-in card.
3.Award Bios BEEP Codes
1 Long Beep: Memory problem
Explanation: There is a failure of some sort related to the system memory.
Diagnosis: The first bank of memory probably has a failure of some sort; this is usually just a physical problem such as an incorrectly inserted module, but may also mean a bad memory chip in a module. It is possible that there is a failure related to the motherboard or a system device as well.

• 1 Long, then 2 Short Beeps: Video error
Explanation: The BIOS is unable to access the video system in order to write any error messages to the screen.
Diagnosis: This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.
• 1 Long, then 3 Short Beeps: Video error
Explanation: The BIOS is unable to access the video system in order to write any error messages to the screen.
Diagnosis: This is usually caused by a problem with the video card, or the memory on the video card. It can also be a motherboard issue.
• Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.
• Other Beep Codes
Explanation: You have encountered an Award BIOS beep code I do not have documented.
Diagnosis: Award says that any beep patterns other than "one long followed by two short" are likely problems with the system memory. However, of late they have started adding other beep codes to their systems as well.
4.Phoenix BEEP Codes

• 1-1-3
Explanation: Your computer can't read the configuration information stored in the CMOS.
Diagnosis: Replace the motherboard.

• 1-1-4
Explanation: Your BIOS needs to be replaced.
Diagnosis: Got to your motherboard manufacturers web site and download the new Bios.
• 1-2-1
Explanation: You have a bad timer chip on the motherboard.
Diagnosis: Replace the motherboard.
• 1-2-2 or 1-2-3 or 1-3-1 or 1-3-3 or 1-3-4 or 1-4-1
Explanation: Motherboards is bad.
Diagnosis: Replace the motherboard.
• 1-4-2
Explanation: Some of your memory is bad.
Diagnosis: Go to Basic Trouble Shooting
• 1-3-1
Explanation: Motherboards is bad.
Diagnosis: Replace the motherboard.
• 2-_-_ Any combination of beeps after two
Explanation: Some of your memory might be bad.
Diagnosis: Go to Basic Trouble Shooting

The PC does not start.Only it beeps and a red light blinks,also fen is not working.


here are some of the basic codes, depending on which BIOS you have...

Also you do not indicate which fan? I would guess you mean the main Power Supply (PS)? In which case it could just be you need to replace the PS.

Here is a link to some other codes as well...

Nothing is shown on my Dell Latitude D510 laptop when it is attached to power. No leds, nothing.


1st try a known good AC adapter, see if any change. 2nd, remove all drives, battery, external devices, RAM and wireless cards and see if system powers on and gives memory beep code error. If no change, replace motherboard. If you get beeps, power off, install a RAM module, see if system posts. If it does, add items till you identify the failed component. If no go, replace motherboard. Motherboards are roughly $150 on EBay

Long beep followed by 2 short beeps. Then computer hangs. What is the issue?


I do not know what model laptop you have, but generally IBM beep code of 1L, 2S and a blank screen lead to sequential replacement of:
1.System Board
2. LCD Panel
3. DIMM

This is per their field service manual. In standard desktop PCs this code would indicate a bad or mis-seated video adapter. (hence a laptop system board).

Problem with ibm thinkpad r40


The IBM beep code error 1 long 2 short beeps means there is a video card fault. Reseat your RAM because the video card uses some of the RAM. If it doesn't work then the video chip on the motherboard is faulty, the only way to fix is to replace the motherboard - this may not be a cost effective solution.
Connecting an external monitor to the laptop won't work because the video card also sends data to the video port.

My HP dv5000 laptop has AMI BIOS beep code - 4 beeps


It sounds like either RAM or VIDEO problem to me. (I can't remember the specific beep sequence for AMI bios errors).

Hard to diagnose in Laptops.... if it was a desktop you can just start swapping out the RAM DIMMS..... are you techo enough to check whether you have 1 or 2 RAM cards installed? If 2 then run it with each card in turn to see if it boots (indicating 1 faulty RAM stick). If only 1 then try running MEMTEST on it to see if any errors. (I like HIRENS if you have it... I think it usually has latest MEMTEST on it).

If your cards all pass then its very likely a video problem. If its onboard video with no expansion slot (likely in a laptop) then you may be buggered.

Let me know if you need a hand doing any of the above.
