USB device should be recognized in the bios and make it first boot at the bios boot option menu.Just plug in the usb device before turning on your computer.

No sign of power as well in the computer like blinking lights or something like that? Does the fan still spin?

would be helpful to have the model number of the hp laptop.are you having problem with the cooling fan mounted on the heatsink for the CPU chip ?

If the laptop works, leave the BIOS alone, if you are not familiar with the BIOS settings, I would advise you to let it be or do some research at the HP support website. One wrong setting in BIOS and you have a expensive paperweight. You didn't supply the HP model or the OS?

There seems to be a lot going on here. First I should say, you should never touch a motherboard or any motherboard components when the power is applied to it, as in checking the temperature of the components.

Even a slight touch could cause a static discharge that could result in a motherboard failure.

Usually, when a system will not even show the BIOS screen, I would suspect a failed motherboard.

However, there are some components that can cause this as well.

Here is a link for your system specifications. The beep codes are listed here in the Service and maintenance information.

If you removed or disconnected all the components and the system tried to boot, and gave you some beep codes, it may not be a failed motherboard, but a defective component connected to the motherboard.

First, a VERY IMPORTANT CAUTION. Never boot a compter without the CPU heatsink and thermal paste installed.

This could cause the CPU to burn itself out in just a few seconds.

I would make sure the CPU, with heatsink and thermal paste, is installed. Have no other devices connected, including memory. Boot the system and see if you get any beep codes. If so, add one memory module and reboot the system, and see if you get any beep codes. If so, replace the installed memory module with the other memory module and reboot. See if you get any beep codes. Install the video card if you have one other than an onboard video device.

Since you removed the CMOS battery, the BIOS will be at the default setting. If you can get the system to enter the BIOS, set the time, date and default setting, save your settings and reboot. See how far you can go. If you are successful to this point, you will get an error the no hard drive is found. Now is the time to connect the hard drive and reboot, and see if you are successful.

Hope this helps.

whats the product name ?

The install is corrupt, or you have a hardware problem

Can you please explain briefly what you really wants?
Like FAT32 - NTFS or AHCI - ATA

if you mean the bios battery that saves your clock information, that is located on the motherboard by pushing the click located on the side you will be able to release the battery, they are mostly the type CR2032, check the size before buying...Regards

Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact. Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

You stated " was working fine" , It was working fine in windows 7? windows 8? In Device Manager you can do a scan for hardware changes. Does the webcam show? if no, it might show unknown device if you will have to find the drivers for the webcam at the HP drivers and support. You can try a RE-Boot the software will try to locate a driver, if it cannot it wiil ID it as a unknown device, you will have to find the driver, this is common with a new OS or a upgrade on a machine.

The DC jack in the laptop is a common source of trouble, to no power and intermittent operation. The laptop will need to be dismantled down to the motherboard level to have this addressed.
