Get a blank screen on the first reboot after disabling the secure boot following the procedure in this link: URL....
Model - 15-d017d
(Thats all the info on the back, no product line eg... pavillion, envy, etc)
Tried a hard reset but no joy. Looking at some other posts on this forum, it seems that the next logical step would be to reset the CMOS. Trouble is I can't find any documentation to do with this laptop anywhere, so am unsure of the procedure.
I forget the Bios password and I need to enter to the Bios menu to activate CD boot. My laptop bought in France - I'm french - is an HP Pavillon 15-n031sf Produt : E8P50EA#ABF The OS is Windows 8 64 bits. The code appeared is : 36360064
I have a Compaq 6710b that was given to me for work. My friend put a password on it that requires me write in before the computer will boot in order for me to log-in to my work account. I believe that this is called a BIOS or CMOS or a boot password. My friend said that it is for extra security. I know the password and have no problems getting past this point, but I do not want to have to enter this first password to get to where I log-in onto my work account. The computer was not like this when I got it and I do not want to take it to a tech at work and explain to him what my idiot friend did. The friend does not know how to change it back so that I do not have to enter this password.
I've been losing date and time recently. I update files, then take them home on a USB flash drive and they appear to be older than what's at home. Turns out my date and time are maintaining. I have to reset date and time when I boot up now. Pretty sure I need to swap out the CMOS battery (maybe a CR2032?) how to find it once the case is opened?
i've currently got the back off my laptop and can't realy see the CMOS battery or anything to reset it such as jumpers, the closest I can see is a yellow thing under some casing I cant get to, can anyone supply me with some information with how to reset it on this chassis? i'm not going to have to take the front (keyboard etc) off am I?
i am attempting to replace the CMOS battery in my presario; however, i can't seem to find it. i have tried to search for the service manual for this model but could not find it. i looked at the service manual for the C300 series and it indicated that the CMOS was under the memory module, but it isnt in the same place in mine.
I have a HP G60-126NR laptop. One day, it was stone cold when I press power button. I discharged the mothboard. I then installed a new CMOS battery . I am using the power adapter to power unit. When I press the power button , I get nothing toally dead, except to show the power connection light. If I remove the CMOS battery, then discharge the motherboard again, then plug in , and the laptop powers up without touching power button, and goes into setup screen to enter time. After entering time , it boots into Windows without issue. Windows SFC scan shows no error. If I shut down, not sleep, the laptop is dead again unless I discharge motherboard and start from square one. Also, I want to say that while Windows is running, if I close the lid to put to sleep, you can see that the screen is still active despite changing "what happens when I close lid". My diagnostics tells me it needs a new motherboard. PS: I did flash the BIOS off of HP Website thinking it would resolve my issue, but it did not ....
I have T140p with bluescreens, I've replaced the harddrive, the voltage regulator and disconnected almost every peripheral. but still - have bluescreens. Is it possible that the Cmos battery is responsible for it
Recently replaced the CMOS battery ourselves after getting the 5 beeps. Put everything back together but a couple of screws were loose and came out. Regardless the computer booted up fine and worked for a week. Yesterday it would not power on, at all. Unscrewed everything, opened it up, found some loose connections and tightened up, then replaced missing screws, seemed that they were tight and not spinning in place. Computer powered on fine. Next day, computer powers on again. Then, after a brief power down, it won't come on. AGAIN. Opened everything back up and saw the hard drive was loose so tightened that up via external screw. Put back together and made sure all connections were tight and re-screwed. Still will not power on.
My Father-in-Law gave me his old computer It's an "hpG60 " p/n"NW149UA#ABA" and the model # G60-447CL Notebook PC anyway , when I turned it on it asked me to enter a "Power On Password?" I asked my Father-in-law for it but he could'nt remember where he had put it, boy did we search for it! We didnt have any luck. Can I bypass the Power on Password?
where my laptop would shutdown randomly and give me a real time clock error. I googled around and found that replacing the cmos battery would fix the problem. I tried it out but still i am getting this problem.
My laptop has been messed up ever since I updated it.It all started when I got a notification to update to windows 8.1. It was all good until the next day when I started it up and it would not pick up any Internet connection even though I knew my router was working as I could get an Internet connection on my mobile. I went to the network and sharing center and it said there that it was disabled so I right clicked on it to enable it. After I clicked it, my laptop went to a blue screen and came up with the following message something like this: we've encountered a problem, we're gathering some error info and we will restart your device.
So, it restarted and I tried to re enable the network again and the same thing happened. After about 5 tries the restart thing kept happening. I didn't know what to do so I thought to just restore the laptop. I did that and now it's just in this continuous blue screen restart loop. I can't even get to the log in Window, it just keeps going to the blue Window and then restarting.This is a new laptop, not even 6 months old and it was fine until I was told to update. I'm thinking of just taking it into the repair Centre as I have warranty and I feel as if I can't fix this problem myself as I can't even get into my actual desktop.
HP battery alert system detected battery capacity to be very low error 601 (internal battery). So I changed the cell to a new CR 2032 battery. Showed the same error. I changed to another new CR2032 battery. The second time I did this I had a new 502 CMOS error along with the 601 error. My clock reverted back to 2009, I lost some of the icons on the lower right, and my wireless internet disappeared.
Now I have two things that need to be fixed.
I turned on, immediately hti ESC, hit system diag. F2, Battery Test: Battery Test Primary FAILED (on the first battery I put in, didn't check on the second)
Control - Device Mgr. - HP - Batteries - Microsoft AC Adapter, Microsoft ACPI Compliant Control Method Battery, and Microsoft Composit Battery all show that they work.
System CMOS/realtime clock says its working.
Microsoft System Mgmt. - BIOS Driver v. 6.1.7601.17514 from 6/21/2006 says it's the latest version.
I've manually updated my clock. I'll figure out the wireless and icons later I guess. Just need to know what to do about the errors.
We have some (old) Latitude D510 laptops that are used by students and apparently a couple of them did not have the bios locked out and these kids have discovered this.
We have two machines that are locked out and Dell is not being very helpful in the reset. Of course these machines are way out of warranty and not worth purchasing a new system board which is what Dell is now saying .....
