How do you fix CMOS ( 5302 ) reset message

[Annie97-40_]

I am nearly 70 so please bear with me. My laptop had a problem, it wouldnt turn on without being connected to the mains. Everything else was fine. Its under warranty so was sent back to HP for repair. They replaced the battery but the problem was not solved & loads of settings were no longer the same eg when printing off emails print was HUGE ! Ive had hours of  technicians remotely " doing " stuff on the laptop & am so stressed out with it all ! Since the last technician  was on I keep getting this message " CMOS ( 502) reset. I asked him what it was, he said " we will fix" but he didnt. He was lovely but calling from India & I really struggled to hear him on the hands free whilst trying to press buttons on the laptop! So I still have this message appearing. They want the laptop back but want me to back up my data ! I have no idea how to do this& someone I asked wants £100! Ive been told they WILL DEFINITELY delete all my data to run their tests? I had to send a video of me turning the laptop on without the mains connected! All this because a button doesnt work! Ive discovered that if I use Firefox instead of Chrome to access my BT webmail the printing is perfect & I can live with the fact that I have to always plug the laptop into the mains. Im sorry Im rambling but this has been going on since 4th October. Ive been "Googling" for days? So my question is can they fix this CMOS thing without deleting my data? The man who originally transferred my stuff from from my dead laptop to this new one ( 9 mths ago ) has worried me as he said it might be the motherboard! Someone please Help ! Sorry its sooo long a tale. best wishes Ann

Hi,

There is most likely a problem with the battery and this is causing the CMOS message. The PC BIOS is resetting at every startup.

In older PCs and still in desktops there is a seperate battery which keeps the BIOS settings when the PC is turned off (such as time, date...)

in newer models where the actual main battery is integrated in the notebook, the little power needed for the BIOS is taken from the main battery. Since in your case the main battery or connection is defective you get this message at every reboot.

The best idea is to have the PC fixed, especially if under warranty.

Now probably it is the best idea to back up your data when you send the PC in for repair. I think it is general practice for any repair under warranty as they do not want to take responsibility for data (which can be more important than the actual machine in some cases)

If your data is important to you, you should back your data in any case as computers break and drives can fail. You should back up your data to an external drive or the cloud.

Do you have a lot of personal data on the PC?

Would like a guide on how to backup the data?

Hope it helps,

David

Hi David. Thank you so much for taking the time to reply. You’re absolutely right about the fact that I should learn how to back up. I have photos, videos etc & That apparently comes to 930MB . I have to google everything due to my lack of knowledge. I believe a memory stick would be too small & I would need an external hard drive? I have no clue where you would get one , or if I would be able to do it myself!  As I said previously the man who sorted this stuff out originally wants £100 to back up for me . This is a lot of money ,  & I know it’s not nice to say , but his emails were very pushy & he emphasised that HP will delete everything ! Any advice is very much appreciated, thank you.
