Boot Problems - No Manufacturer Splash Screen

There are many reasons you manufacturer boot screen will not load, or lags. Primary issues include hardware failure, but before concluding this the following techniques may alleviate your problems.

• First update your BIOS from the manufacturers website. The bios update programs typically run on Windows, therefore I hope your Linux machine has a saved Windows partition (ie. Dual Boot)
• Second remove your CMOS battery, your main battery, and the power supply for some time. This can reset your BIOS allowing for setting to be reset to default
• Put everything back together and try to boot. If you still have problems use a multimeter to read the voltage of your CMOS batter. It should be 3-3.3 Volts.

If none of these techniques relieved your issues you may indeed have a hardware failure. Albeit I have warranty service, but it takes weeks to get your machine back. I guess the only good aspect of  warranty service is that it is free

CMOS Battery Soldered Connection

Desktop PC’s typically have a clip on their motherboard where the CMOS battery sits. On laptops sometimes the CMOS battery is unreachable. On the HP DV2000 The CMOS batter is located under the hard drive panel, and has a 3 pin connection to the motherboard. The connection clip is attached to the battery via solder points, and therefore to replace the CMOS battery in this machine you will have to remove the soldered connections, and re-solder them to the new battery.
