I made the mistake of applying a BIOS update very close to the same time that I had applied Vista SP1 on aDell Inspiron 1525. After applying both updates, the laptop would consistently reboot when put to sleep (hardreboot instead of sleep), and would reboot instead of shutting down when hibernating after committing thememory image to disk. Rolling back SP1 would make the problem intermittent, but did not resolve completely. Reapplying SP1 and rolling the BIOS back to A09 seems to have resolve the issue.
Is there a known incompatability with BIOS A11 and Vista SP1 on the Inspiron 1525?
I had the same problem with my 1525 (preloaded with SP1) after "upgrading" to A11. After successfully going into hibernate, the machine would reboot! Not very useful. I fixed this by downgrading to A09 and that seems to have fixed the problem. It also may have fixed another problem: the wireless connection would be confused after coming out of hibernation and only had "local access", i.e., no Internet. I'd have to reconnect and that would solve the problem--it would always reconnect manually properly. After "downgrading" the BIOS, I reconnect to the wireless after hibernation with no problem.
I think that A11 BIOS has some issues.
Interesting. I will sticky this thread to the top and see if other users are reporting the same symptoms.
Have you upgraded to SP1 as well?
My 1525 came without OS, i've installed Vista with SP 1 integrated and after finishing with drivers & stuff, i've upgraded bios to A11.
I have no problem with sleep/hibernate/restart/shutdown .. everything is working as it suppose to ..
same problem here i realy didnt knew where to post it but here it goes:
I setup vista, installed drivers and updated bios.
Since sp1 i dont remember before, the insp 1525 almost every time i want to hibernate the pc it will reboot after the end of the hibernate process wich takes a while too.
I found several things about this that i thought could be the problem too but im not sure about it:
Check this out 1525 Vista sp1 users:
1. Do "Properties" On "My computer"
2. at button "See Also" click "Performance"
3. at "Tasks" click "Advanced Tools"
4. at the "Performance Issues" you may see:
"/!\ Drivers are interfering with Windows entering sleep mode. View details."
5. click that line and a window will pop up. saying:
"These drivers are causing windows to stand by or hibernate slowly"
Name: Intel Matrix Storage Manager driver - ia32
Publisher: Intel Corp.
Device: intel(r) 82801HEM/HBM SATA AHCI Controller

"If you no longer use the device, consider uninstalling it. For more information click HELP"
6. donno what to do to resolve the issue
Running: dell insp. 1525/ WinVista sp1
Could be the difference because i don't have any "issues" in "Performance Issues"
in my case ...
I've used Vista Manager to check and there isn't any Intel Matrix Storage just one Intel RAID Controller Vista which is listed as Disabled.
Also, there isn't any iaStor.sys file present in \System32\Drivers but there is iastorv.sys
So .. I've downloaded R166201 (Intel Turbo Memory), which by default install also Matrix Storage Manager.
Then, i realized that R166201 comes with an older version of iastor.sys (184.108.40.2061) and updated driver with R166200 where version is 220.127.116.117, restarted and...is entering in sleep mode without problems.
sorry guys .. if that is the problem is very likely that an updated version of driver (after SP1) will solve the problem but as i described above, in my 1525, there isn't any symptoms, sleep is working as it should be.
Exactly the same problem for my new Inspiron 1525 (of less than a week) with A11 and Vista SP1: sleep always restarts the PC with the screen for choosing fail safe mode or other modes; hibernation restarts Winidows simply.
The 'powercfg -a' command says that S3 (hibernation) is available, but not S1 and S2 (standby), because not supported by the BIOS. It is true that in the BIOS there is nothing about standby or hibernation. Are there items in your BIOS about standby/hibernation?
I have found a way to shut down the PC with the Windows menu (instead of the power button): in a Dos command window, do "powercfg -h off"; disable hibernation in the power management of Windows, then the PC can be shut down normally.
