The power source is like the ones from laptops, don’t panic if you don’t see the classic power source.
Read the manual and plug the power cables, the yellow jack and the adaptor.
Bios settings
In order to enter Bios, hit the F1 (press it repeatedly), instead of the old “Delete”.
In order to install Windows XP.
From Bios, select “Legacy only”.
The selecting arrows are “-” and “+” from numpad. So it’s minus and plus.
Also from Bios, select “IDE” instead of “AHCI” if you want to install Windows XP. If you don’t do that, you will get a blue screen when Windows is starting its installation.
If you want to install Windows Vista, 7 or 8, don’t modify anything from Bios.
Drivers
For Windows XP.
Place the CD with the drivers and install what you find from the autorun interface. You won’t be able to install the important drivers from there though.
First thing to do is to install the LAN driver.
The Windows XP LAN driver is located on the CD. With Windows Exploder, browse the CD > RTL8111 > Nonvista > install the driver you find there.
Connect the LAN cable and restart the PC, the network should work after.
The graphic card drivers are not present on the CD. Search on Google “Intel HD 4000 graphics driver for Windows XP”. Download and install what you find.
For the audio driver, search on Google: Realtek AC 97 driver for Windows XP, download and install what you find.
For Windows Vista, 7 and 8, install all the drivers from the CD, the autorun interface.
After Windows was installed and is running, restart the PC and remove the DVD-RW from primary boot. Remember, with + and – from numpad.
The same steps can be applied to other Lenovo desktop PCs from the “H” series, H500S for example.

I have H500s and i cant get to install anything except W8.
Tried your advice but with no success.
For win7 acpi is problem, XP with F7 i bypass acpi but after startup after i press enter to continue when it must show hdd it just restart…
Any advice would be greatly appreciated.
I got blue screen when installing XP when it was set to ahci. So you need to set ide before installing xp.
I don’t know how you can bypass it.
For Windows 7, you should be able to install it with ahci enabled. But if you try that and doesn’t work, try it with ide.
You might want to check from bios, boot priority if your hdd is displayed there. And set it as primary boot device.
Anyway, to install xp, set legacy and ide.
More recent windows, vista, 7 and 8, set to ahci; non legacy (I don’t remember how the option is called but you can find in the pc’s manual)
I lost my power adapter.
and searched lot but not get in market.
Is there have option to fit SMPS.
or any other solution ?
The yellow rectanngular power jack is the main problem even if I get the similar watt and voltage adapter.
Please suggest the solution
@mit,
From what I see, the PC is using a basic laptop power adapter.
I would go to a PC store where they have technicians, tell them what PC you have and that you need a power adapter.
Can we modify this PC? Can I replace the Laptop type power adapter with regular desktop SMPS if I have to? This one does not has USB 3.0 ports. Can we replace the system Board with the boards available in the market (one with USB 3.0 Ports) and replace the front USB 2.0 ports with 3.0 ports? With its original configuration, can also run Windows 10? Please advise.
@Ron. It should be able to run Windows 10.
I don’t think you can use a regular power source on the current motherboard as it doesn’t have the jack slots.
I’ve bought a separated power adapter for such a PC, it didn’t costed that much, around 20 euros. It looked the same as the original one. If yours is failing.
You might be able to buy a new motherboard, but you need to make sure that it is compatible with your processor. And it needs to have an internal video card. Better ask for advice on a hardware store.
And replacing the power button from the case (the wires)/usb slots is no easy task.
To be honest, I would leave the system as it is.
