It may be a hardware error. Call HP and see about your warranty.
A lot of HP's new laptops have hardware defects, which could happen at any time from the day you buy it. Have it sent in and have it repaired for free.

Try hooking the laptop to a desktop monitor. This will verify what is failing. If all works, then you have a bad LCD screen. If you get the same problem, you have a motherboard problem which is probably not worth fixing.

SOURCE: HP G61 NOTEBOOK PC BIOS

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. :/

I have a fujitsu e8410 which will not start up properly, when i push the start button it shows power but then the fan comes on and the cap num and shift lock leds flash and nothing else. can you help?


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

My laptop screen is black and caps lock and scroll key are flashing


That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.

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 Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. 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

Hello,

There are a number of things that can cause this to happen. Try taking the battery out of the notebook, disconnect the AC adaptor (if in use) press the power button a few times. Re-install the battery, reconnect the AC (if needed), press and hold the power button for about 2 seconds. This is a hard reboot and should correct you issue. When the notebook powers up, make sure you remove any cd's in the cd-rom drive.

Good Luck,

Bootin problem


This could be a number of issues. What you are referring to is known as failing to post. The culprit behind this error is most likely motherboard or memory. If you have 2 sticks of memory, try taking one out. If nothing swap memory again. Still nothing, have motherboard looked at.

Motherboard. Your best bet is to purchase another computer. If you can however get the motherboard at a cheap price, then go ahead and change it. I would check ebay first.

Sleep Mode Lockup on Dell Inspirion 530 w/ Vista


Try hitting the "Windows" key on your keyboard to bring it out of sleep mode. The "Windows" key is generally found on the bottom row of the keyboard, near the Alt and Ctrl keys, and it has no letters on it, just the Windows logo. That key brings my Windows Vista machines out of sleep mode when other keys won't.

As for the power button, anytime you need to force a computer to turn off, you can press and hold the power button to do so. Usually, you need to hold the power button for 5-10 seconds and it will shut down. Use this option with caution, as it turns the computer off without running through the shutdown process and can cause you to lose data.

Hope this helps.
