Error Resource Conflict Pci Serial Bus Controller In Slot 01 Toshiba
I have problem with my Acer Aspire 7520G. When I turn it on, after memory check and disk check I got messages:Resource Conflict PCI Serial Bus Controler in slot 01Bus:01 Device:04 Function:00ERRORBus:01 Device:04 Function:01ERRORBus:01 Device:04 Function:02ERRORBus:01 Device:04 Function:03ERRORBus:01 Device:04 Function:04ERRORafter this wont boot neither from HDD nor CD/DVD. Just blink currsor apears.After a few of restarts, if I got luck, it will boot up 'normally'. I checked in Windows system that Bus 01 Device 04 is acctualyRicoh 1394 OHCI Compliant Host Controller at Function 00,SDA Standard Compliant SD Host Controller at Function 01,Ricoh SD/MMC Host controller at Function 02,Ricoh Memory Stick Controller at Function 03,Ricoh xD-Picture Card Controller at function 04.I beg for your help.Sincerely.Arnes G.Bosnia and Herzegovina.
This could be a hardware problem. Just to be safe, try resetting BIOS values to default. If I remember correctly, this is the procedure:0.
Turn off the computer1. Disconnect it from its power supply2. Remove the battery.3. Press power button and keep it pressed4. While the power button is pressed, connect the power supply unitThe BIOS data should now be set to their default values.If it doesn't help, update your BIOS to the newest version. I think it's 1.33, but I'm not certain.
You can get it from Acer's support site.Just to be safe, does the error message show before OS starts or after? If it shows after OS has started, then it could be related to drivers. I know that the firewire/memory card controller is of low quality and that people were having trouble with it but I haven't heard anything about it failing. Try with newest drivers from Acer's site for memory card reader. In the end try to reinstall OS.If you still can't solve your problem, post here. Acronis backup cloud.
Hopefully someone will be able to help you.h. Yes, its definitely a hardware problem.I can enter into BIOS and I load default values, so disconnecting battery will not help. (I think).Bios version is already 1.33.
And error message shows before any OS start. It shows after RAM check and HDD check.
Then shows:SYSTEM BIOS VER 1.33STRONG ROM VERSION 03.30ERRORResource Conflict PCI Serial BUS Controler in slot 01. Etc.When I have luck to boot OS (Windows 7 in my case) it shows that driver can not be loaded. So something is dead on my mainboard. But this is only my thinking.
Well did you try all the steps I pointed out above(some people say that you need to keep the power button pressed for 20 seconds)?If these don't help, then it's probably a hardware problem. Unless you know someone who deals with computer electronics, you'll probably find it cheaper to just replace the laptop, because I think that the official 'authorised Service Centres' are just going to tell you that you need to replace your motherboard.Here's the list of Acer's service centers, if you want to send it to be repaired.
There are a few in Sarajevo and one in Vitez.Did you do anything to the laptop before the problem appeared? Like leaving it near a powerful heat source or in a car in the summern or something like that? It looks to me like the soldering on contacts for the Ricoh's chip isn't working properly, but I too am just guessing.If everything else fails and repair of the laptop proves to be economically unjustifiable, you could try to bake the motherboard (there are guides on the Internet). It might fix the bad soldering, if that's the problem.I'm out of ideas. The battery on 7520 in not soldered! There are two switches on the bottom of the laptop. One small and is used to lock and unlock the battery and has a small padlock engraved next to it and other is long and has a battery engraved.
It is used to eject the battery once it's unlocked. Unlock the battery and push the long switch to the left (right if your laptop is upside-down) it will eject.It's actually pretty easy to open 7520.
I you need instructions, I can help you.I don't know if the laptop will work without the chip. Basically if you are ready to scrap the laptop, then you could try to remove the chip. Again, it could be difficult because of the way the chip is attached to the motherboard. Take a look at the link below.As for the baking option, it simulates the factory soldering. Take a look here.
IN DECEMBER, 2011 A USER RAN INTO THIS PROBLEM.There is a list of several Motherboard 'resource conflict' errors that show up on the black screen when I do various things like hit Esc at startup or go through System Information. Would that list help solve any mysteries? Is my motherboard just shot? Here is the list:ERRORResource Conflict - PCI Serial Bus Controller on MotherboardBus: 02, Device: 05, Function: 00ERRORResource Conflict - PCI on MotherboardBus: 02, Device: 05, Function: 01ERRORResource Conflict - PCI on MotherboardBus: 02, Device: 05, Function: 02ERRORResource Conflict - PCI on MotherboardBus: 02, Device: 05, Function: 03ERRORResource Conflict - PCI on MotherboardBus: 02, Device: 05, Function: 04.Another symptom was that it would just sit.with the option to 'Press any key to boot from CD or DVD'.

In fact, I was only able to see the Resource Conflict error, above, after I selected F10, as if I was going to run a Memory or Hard Drive test. The error flashed across the screen, so I literally had to take a picture of it in order to view it. Hope your experience is different!Well, today, I ran into the exact same problem with a machine I was trying to upgrade for a friend and, thankfully, I was able to resolve it.The error simply means that multiple devices are trying to use the same resources on your motherboard. What I had to do is go into the System BIOS and reset the BIOS back to its default settings. That was it!After that, the conflicts were gone and I was able to boot from DVD/CD-ROM and restore the computer back to operational status, complete with additional memory and a new OS.Best Regards,Henry.
