SOURCE: lenovo g530 4151 - restore bios from USB or CD ?

Hi, What I would best sugget you if you this kind of issue is to restore your system to its original settings, just look for the small button just beside the power button on your keyboard, it has an arching arrow logo, that key is what we called One Key Recovery that would restore your system to its original factory settings. but just a hint it would also delete everything on your computer so consider bucking up every important files taht you have before proceeding with the recovery. also make sure that the ac adapter is plugin before you press the one key recovery button then it will give the options to choose from, just choose one key recovey then proceed with the factory default recovery, thats it it would now proceed with the system factory default restoration. If you still need some clarifications regarding this issue you could also call the tech support hotline of lenovo

Laptop LED Blink on Startup
There are many reasons that a computer does not startup or boot into the Windows operating system. If your computer will not start or boot, you will see or hear symptom to indicate the general area of the problem.
Startup Symptom: LEDs blink but does not start
The blinking LED lights on newer computers, or the beep tones on older computers, will help support agent determine what hardware component is not responding properly. The exact meaning of each code varies with the model, and the user cannot change any of the blink or beep codes.
DO THESE FIRST - Perform a hard reset.
If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.
1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery and then press and hold the power button for at least 15 seconds.
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Identify the number of blinks or beeps
When there is a start-up problem and you see LED lights on the keyboard blink a few times (between 1 and 8 blinks) do the following actions.
Table of Sample Blink Codes
The following table illustrates the meaning of blink codes used on some notebooks. The blink or beep codes on your computer may have different meanings.
Meaning of Sample Blink Codes for some EFI Notebooks:
1) Number of Blink: Continuous Glow, Blinking LED: Battery power LED, Component: Battery,
Error Condition: The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook.
2) Number of Blink: 1, Blinking LED: Caps Lock/Num Lock, Component: CPU,
Error Condition: CPU not functional
3) Number of Blink: 2, Blinking LED: Caps Lock/Num Lock, Component: BIOS,
Error Condition: BIOS corruption failure
4) Number of Blink: 3, Blinking LED: Caps Lock/Num Lock, Component: Memory,
Error Condition: Module error not functional
5) Number of Blink: 4, Blinking LED: Caps Lock/Num Lock, Component: Graphics,
Error Condition: Graphics controller not functional.
6) Number of Blink: 5, Blinking LED: Caps Lock/Num Lock, Component: system board,
Error Condition: General system board failure.
7) Number of Blink: 6, Blinking LED: Caps Lock/Num Lock, Component: BIOS,
Error Condition: BIOS authentication failure.
8) Number of Blink: Continuous blink, Blinking LED: AC power adapter LED, Component: Power adapter,
Error Condition: Insufficient power
Common solutions for issues that cause blinking LEDs or beep tones
When the computer can boot into the BIOS, run the memory test to identify other issues.
Check for loose connections and test the memory
Blink codes are often displayed after a user adds memory to the computer but does not seat the module properly. The LEDs may also blink error codes if a hardware component is loose because the computer was dropped or jarred. The problem could be that the stick of memory or one of the memory slots has a bad connection.
Check for loose memory modules
If a memory module is loose or is not making good contact with the memory slots, the computer does not recognize all of the memory. Reseating the memory module may resolve memory failure errors.

On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/

HP Black screen error codes

Support details

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes.
The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved.

Battery power LED blinks

The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition.

Battery low charge or failure
Battery power LED blinking Battery Insufficient charge on the battery

LEDs near Caps Lock and Number Lock keys blink when starting notebook
The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up.

If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition.
Knowing the number of blinks is helpful when you contact an HP support agent for technical help.
Caps Lock/Num Lock LED Component Tested Error Condition

LEDs blink 1 time CPU CPU not functional
LEDs blink 2 times BIOS BIOS corruption failure
LEDs blink 3 times Memory Module error not functional
LEDs blink 4 times Graphics Graphics controller not functional
LEDs blink 5 times System board General system board failure
LEDs blink 6 times BIOS BIOS authentication failure

Error code explanations
The sections below provide some common explanations for each error code listed in the table above.

AC Adapter not connected or battery low charge
When the computer is on battery power only and the AC adapter is disconnected, if the Battery Power and Caps Lock / Number Lock LEDs do not glow, there is either a very low change or no charge in the battery. Connect the AC power adapter, verify that the battery power LED glows, allow the battery to charge for 15 - 30 minutes and then attempt to start the computer. If it starts, run the battery test and calibrate the battery. If it does not start, if possible, connect a replacement battery to verify that the battery is the problem.

If the computer does not start after charging the battery, remove the battery and connect the AC power supply. Verify that the battery power LED glows, and then attempt to start the computer. If the LED still does not glow, either the AC adapter has failed, or there is a bad connection between the adapter and the system board. If possible, connect a different AC power adapter to verify that the adapter is the problem, or contact HP for support which may require a service event.

Insufficient charge on the battery
If the battery light LED (which looks like a lightning bolt ) flashes, the battery has insufficient charge to start the computer. To resolve this error, try the following solutions.

*
Connect the notebook PC to AC power and attempt to start the computer again.
o
Check the AC adapter to confirm that all of the plugs are securely seated.
o
Determine if the power LED on the AC adapter is lit (if available) to verify that the computer is receiving AC power from the wall outlet.
*
If the computer operates on AC power correctly, charge the battery for thirty minutes to one hour and then restart the computer.
NOTE: Charging the battery for this length of time is called "trickle charging". Trickle charging is a continuous constant-current charge at a low rate, which recharges the battery slowly when it is in a deep discharge state. Deep discharge occurs when a battery is left unused for extended periods of time.

The computer processor (Blink code 1) has stopped functioning properly. Contact HP for assistance.

BIOS corruption failure
If a BIOS corruption error occurs (Blink code 2), you may not even notice the blink codes, because as soon as the computer recognizes the error, it restarts, attempts to recover the BIOS, and then restarts again. You may notice an extra-long startup process as a result, and a message indicating that the BIOS has been recovered may display on startup. If this occurs, update the BIOS on the computer. For more information, refer to the HP Notebook PCs - Locate and Install Updated BIOS, Drivers, and Software .

Module error not functional
If you experience a memory failure (Blink code 3), follow the guide in the table below.
If Using Original Memory If New Memory Is Added
Reseat the memory.

If reseating the memory does not resolve the problem, try replacing the memory with new memory. Reseat the memory.

If you continue to experience this error code after reseating the memory, the problem may be with the memory itself. Take the new memory out of the computer, put the original memory back into the computer, and then retest it.

If you do not feel comfortable reseating the memory yourself, take the computer to a computer retailer and ask them to reseat it for you.
NOTE: Some memory module errors may allow the computer to start but will then cause the computer to restart and display a blinking error code.

Graphics controller not functional
If you experience a graphics controller failure (Blink code 4), contact HP for assistance.

General system board failure
A general system board failure (Blink code 5) is the failure of a component not covered by the other LED error codes. Contact HP for assistance.

BIOS authentication failure
The BIOS authentication error (Blink code 6) is extremely rare. It is the result of a discrepancy between the BIOS and the hardware that is installed on the computer. This error occurs when the BIOS cannot authenticate signatures from the hardware on the system. The purpose of the BIOS authentication is to be sure that no one has tampered with the BIOS on the computer.
If a BIOS authentication failure occurs, the computer automatically performs a BIOS recovery. If the computer does not automatically recover the BIOS, manually perform a BIOS recovery. To manually perform a BIOS recovery, press all four arrow keys at the same time to cause the BIOS to go to the EFI partition to find and recover the current BIOS.

Tecra M2 doesn't boot is it a processor problem?


given the symptoms, it points to motherboard.. if it was processor, video or ram. it wouldnt boot at all and you'd just get error beeps from your laptop. i'd first try resetting the bios, by removing the bios battery for 30 min, then putting it back in. if that doesnt work try changing it out, usually costs under 8 bucks. if that doesnt work then I would change out the motherboard, if its cost effective.
