Sounds more like a power supply problem. Easy fix just install a new power supply or try it with a known good supply.

Could a dead bios battery result in a blank black screen?

The EEPROM is not the copy of the BIOS used to boot the OS or effect settings. The EEPROM defaults get copied into CMOS memory (hence why it is called the CMOS battery). So if the CMOS battery is dead then there is nothing to energize the CMOS chip to retain its values. That means on every boot you will get the defaults loaded from EEPROM. It will not cause black screen.
you do not give much info, does machine come on and runs but screen is black, or computer dose not start at all, more detail would help, press the helpful button and RE POST with more info

sounds like your motherboard malfunctioned. the board was probably starting to go out. thats why it would see the hdd then not.

you sound like youre familiar with computers. you may want to invest in diagnostic cards to troubleshoot problems like this. theyre fairly inexpensive on ebay. basically you insert the card into pci slot and it displays an error code. then you look up the code in a book. works like the obd2 reader for your car.

good luck

Okay so my hp dv2451nr wont start up meaning it turns on but the screen is black i held the power key down and unpluged it then plug it it back in and now the fan finally started up but now near the...

all old laptops, 101. asked here 100s of times,1000s, and answered as much,in IN DEPTH,
the pc will run for eternity on AC power no battery main
you do know that right> so do that first.
the fan is working, that is a good sign. sign of power may be ok.

1: the screen never shows text, like it did for 10 years.?
2: take out that old bad shorted main battery , does it run on AC now?
yes, no. (yes do the HP long reset, posted 1million times at HP and here,....both here and hp real forums.
(battery out, ac pack out, push power on, for 10 -30 seconds)
there 1,000,001 times.

3: no text?,got text? yes/ no. (if yes, does BIOS work) f10 prompted for 10 long years, still on the screen yes, then., this.

no text means the screen back laps are burned out or the AC pack is bad (or 20 other reasons seen in the link below)
(this is the most cheap fix of all)
4: the coin cell, RTC CMOS , is it 10 years old too.?
this kills the BIOS dead, so will be all things dead if BIOS is chaos.
BIOS uses the RTC ram to save settings, so.........coin must be good, 2.9v and more ok. less bad.
5: i stop here and show a link.

no beeps, no caps lock key blink codes..... RTM?
the pc here can be as old as 2007
if yes, then it can have CCFL, backlamps that love to fail now or sooner.
see this.

Left computer running with charger connected. Screen went blank and light showing power connected was no longer lit. New charger did not solve it. New battery (with some charge) worked. Still no charge so...

If your charger is working properly and the laptop is as well, then the laptop should work without a battery in it at all. If your new battery worked and laptop worked with it until the battery died, then the charger or charge port is damaged.

If it does not work with charger plugged in without a battery, then your charger(s) or the laptop charge port itself may be damage or broken. Or worse, the laptop may be dead.

If the laptop does nothing even with a good battery with charge (no fans, no boot, nothing on-screen, no noises) you're laptop could be dead; likely a burned motherboard or processor. It may have overheated or something along those lines.

Odds are there was a power grid surge (especially given the fact that your son's is dead as well. Typically replacing the Ac adapter (power cord) will fix the problem, the ac adapter is designed to take the blow in the event of a power surge.

Dell inspiron 5150 do not come on when the power button pressed

If you remove the battery and disconnect power cord, then hold power button for 20 seconds, then reconnect power cord but do not re-insert battery, and the unit powers on okay, the problem may be your battery. If there is still an intermittent problem, the power connector inside the unit may be loose and need re-soldering, or you could have a bad power supply.

Notebook not starting and screen remains blank.

this will be easer than you think.
first unplug power cord,pull out your battery and test it by pushing the button on the battery. It will be dead. leave it out. plug in power cord, nothing should work. test your power cord. if nothing than test lower on the cord it might be the plug in that plugs into the laptop. what happens is the battery get to low and the lappy goes into a safe mode . you will need a charged battery to get it to boot.

I’m happy to assist further over the phone at
