My dc 7800 CMT automatically starts as soon as I turn on the power supply, despite not pressing the power button. Also the CMOS data gets lost/corrupted every time the PSU is switched off/on (looks like the CR 2032 batt no longer sustains CMOS, even it's brand new giving full 3V). Moreover, when I put it into sleep mode from the OS and later try to wake it up it won't and the CPU fan starts spinning with full speed. What could be causing all this?

Pressing F1 will record the new configuration. If this message persists you may need to replace the onboard battery.

Set the time and date. Clearing the CMOS on your motherboard will reset your BIOS settings to their factory defaults. After clearing the CMOS, you'll need to access the BIOS setup utility and reconfigure your hardware settings. You might need to clear the CMOS for several reasons but usually you'll want to clear the CMOS to help troubleshoot or solve certain PC problems like hardware compatibility issues. Sometimes you will have to remove the battery to fully clear the settings. Many modern motherboards are starting to come with a power, reset, and clear cmos button built right into the board. Those are easy and you won't require those steps. Just press and hold one of those buttons down, with the machine off but plugged in. You might need a standard PS2 keyboard instead of a USB keyboard temporarily. After resetting the BIOS it is not set to use the USB during the boot up. You need the old style keyboard to plug into the purple port on the motherboard. After you get into the BIOS enable the USB ports.

Love your work brother but I have 2 HP Compaq dc7900 that I am trying to figure out how to fix them. One of them beeps 4 times when I turn on and the other five times. I tried removing all the parts but still the same beep errors. Yes they were dusty when I got them but I thot cleaning the parts one by one would fix the issue. Can you help me see what the hell is wrong with these Machines plz, PS: I bought them for 250USD each thinking they would wok for my children came use for there school assignment. The America Pease corp volunteer guy I bought them from left the Island and gone back to America. So I cant reimburse my money and kick his ass then take him to court. Is there another way to fix these PCs?

The most common problems that cause beeping sounds are: Memory and heat-related failures caused by a build-up of dust in critical cooling areas. A keyboard key is stuck. A memory DIMM or hard drive cable is not seated properly.
@AlwynNicholas
@AlwynNicholas 3 года назад
Disconnect the mouse and keyboard, and then restart the computer. If the beeping sound stops, repair or replace those devices. Hot air can damage internal components! Remove any obstructions that block vents.
@AlwynNicholas
@AlwynNicholas 3 года назад
The 5 beeps is a memory or motherboard problem. I would remove all but one of the memory modules and test each one individually and find the one (s) that may be bad.

@AlwynNicholas
@AlwynNicholas 3 года назад
Red Power LED flashes ten times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. 10 Bad option card. Check each option card by removing the card (one at a time if multiple cards), then power on the system to see if fault goes away. Once a bad card is identified, remove and replace the bad option card. Replace the system board.
