HP530 Laptop - Freezing / Blankscreen on reboot

eddiem74

Just wanted to see if you guys had any ideas??

I bought a HP530 laptop from Dabs.ie in January. It was working fine for a few months, than it started to freeze when in the middle of web browsing or really any mouse movement a couple of times a day.

The only way to get out of this was a forced shutdown, and then when I would switch the laptop back on it would just sit there with a blank black screen, and not do anything, although I could hear fans etc. spinning. To boot up from this I would either have to do a hard shutdown a few more times, or more typically, remove ac power, remove battery, and then reconnect them and it would boot up no problem.

I have installed the latest bios from the HP Site, and also un/re-installed the graphics driver, and then finally I also done a complete OS reinstall (vista basic) but this issue is still there, although not as frequent. I have also removed and re-seated the ram, and also the harddisk in case anything was loose but to no avail.

Any other thought's ? Things I could check ? Ideas what could be the issue ?

Is the Cpu cooling fan spinning at all.?

Try running some cpu intensive programs and see if the fan will spin.

The laptop maybe over heating.

I would get in touch with DABS, seeing that it is less than a year old it's probably still under warranty.
You have tried updating bios, graphics drivers and a fresh install of windows, after that i'd be thinking hardware issues.

OP could you tell me what your CPU and RAM situation is like? You might have a machine thats underpowered for running vista. That and if your system is running in a power saving mode the CPU would be limited from going over 50% of its true capacity, giving you even less to work with. Check that the power plan you are using is High Performance. This could be leading to your freeze-ups, if the CPU is spending all of that time trying to work. Another tell-tale symptom is the hard drive light: on an HP laptop this should be right next to the power and charging light. If that light is on your hard drive is trying to read/write. Again, the freeze up could be from low RAM, and your hard drive would have to compensate by using Virtual Memory - which is much slower.

Yes fan sounds to be spinning, and when it gets stuck with the black/blank screen on hard reboot I can hear it??

Vista Basic
2GB Ram
Core Duo T2400 @ 1.83GHz
120GB Harddrive

Was not in High Performance Mode, is now ! Will see if that helps !

Hi,

I have HP530 too...with overheating problem, ofcourse :mad:

my problem is next: when I wanna instal fresh copy of xp, vista, etc. computer just freezes because of overheating... I got it from service today and took them 14 day t odo NOTHING. I know that there is problem in cooler beacause CPU has around 85°C and air from cooling fan is warm and not hot... when it was new, it was blowinhg hot air...

and fan is going nuts all the time...

to you think that fan body could be somehow dislocated from original position??

and do you maybe know where could I find guide for dismantle that laptop..

THANKYOU in advance!!

Well if the laptop is still under warranty then don't take it apart or you will void it.

Didn't help, on to HP Support via the web, going through the motions before a return I reckon ! :rolleyes:

Tomorrow I'm calling hp service directly and maybe even go there... I will report what have I done to solve that problem... I think we both have simillar problems...

Downloaded speedfan, and ran a HP Online diagnostics.

Speedfan showed local temp of mid-high 50's and other temps in the 70's with a CPU utilization of around 50% while running the diagnostics. With nothing running temps dropped to the 50/60's.

The hardware diagnostics highlighted a possible faulty hard drive. I contacted HP Chat support again, they had me run a bios self-test which also gave a read failure. So they directed me to HP Phone Support who are sending me a new hard drive which hopefully will solve the issue.
