I got a hp 1000-1405tu notebook ). I m experiencing a very weird problem. My notebook shuts down - not the "windows is shutting down" type, but immediate loos of power shut down. I thought it was shutting down because it was overheating, to eliminate the overheating option i installed SpeedFan and in some cases (idling, music, movies) temperature was about 40-50 Deg C. but i cleaned it with compressed air just in case. I thought it might be a virus (even though i have antivirus program), so i tried booting up in safe mode - same effect, tried leaving it in BIOS - same effect but then i noticed it is shutting down exactly 30 minutes after powering up. doesn't matter if i'm playing games, watching movies, listening to music or letting it idle - at 30min. mark it just powers off. i tested it on battery power, on main supply with and without battery - the effect is always the same. Hard Disk test - PASSED Memory Test - PASSED Battery Test - PASSED

If it is a faulty motherboard issue is it repairable? what IC causes the pc to act like this

Did you check for a BIOS update? Make sure your BIOS has latest version.

After that, I would suggest you reset BIOS to default settings.

Also, just in case this could be a bug in SpeedFan, check your temps with HWMonitor or another software as well.

I have seen some wierd things with laptops. In some cases I have found removing a defective battery and just running on power is fine. Try this and see how it works. Also, I have found defective power adapters to also cause some very strange issues with laptops as well. How long have you had this laptop?

sorry mistakenly pressed Take it as an answer though my problem isn't solved. I looked through HP support website and there was no upgrade available for my model. Then I downgraded the bios to an older version. My Bios was of version F.35 and downgraded it to F.3A. Even after the downgrade there was no visual change.


I m pretty sure about that it's not overheating issue. I've checked with HW monitor, under different processor load temp varied between 35 to 45 approximately. Moreover it seems cool when touched with hand under the heat generation region. Even after, I have cleaned the air vents. Its a new laptop.

It acts the same under the battery power or under the mains power with battery opened. It just runs for 30 minutes and then shuts off. If started immediately after shut off, it runs again for next 30 minutes.

What I was getting at is remove the battery, and then run it under the power adapter. Sometimes a faulty battery can cause a system to respond inappropriately.

When you say with battery "opened", you mean with the battery taken out of the laptop?

Since the older BIOS version didn't fix it, I would flash it back to latest version. Then I would reset it to default settings.

If the reset to default settings doesn't fix it, there are are many power management options in your BIOS so I would suspect one of them is causing the issue. Check your motherboard manual to see what you can enable or disable regarding this.

I just re-read your post, it sounds like battery open means you removed the battery and tried it.

Does the battery even show that it is charging when the AC adapter is connected? If it only runs for 30 mins everytime, maybe it just runs on the charged batter until it dies? Maybe the charger/adapter is not working properly? Once it shutsdown, can you turn it right back on and it will run for another 30mins? On battery power as well?

Once it shutsdown, I can turn it right back on and it will run for another 30mins. Whatever the power source is battery power or adapter. Yes, I've tried removing the battery and running the laptop on AC adapter,it results the same. The battery charges fine and continuosly runs for nearly 4 hours with interval at each 30 minutes.

I can't find the BIOS version which was initially installed in my laptop throughout the hp support website. It was Insyde BIOS F.35 for hp 1000-1405tu notebook. Tried recovering the earlier BIOS follwing instructions mentioned in hp support website by UEFI tool. But my attempt wasn't successful. Very upset for the problem.

Weird. When I go to the Support section of the HP website and search for "hp 1000-1405tu" nothing comes up. I did a Google search to make sure this was not a typo, and this model exists. Google even links to the HP support for this product among its first results, but the page isn't working either:

http://h10025.www1.hp.com/ewfrf/wc/product?cc=ca&lc=en&...

I think someone at HP broke the support page for this product. It should be back eventually. I was just checking to give you link for you to get the latest BIOS version.

In the meantime, did you reset the BIOS to default settings as I suggested previously?

Did you also check your motherboard manual (BIOS section) for any option related to power management in your BIOS? I would turn off some of those options if you can and see if it makes a difference.
