Your HP All-in-One 24 will not switch on. The screen stays black, there is no light and no fan sound. Someone says the board is gone and a new board is needed. Someone else says the fault may be small and can be repaired on the board itself. Which one is true? This post explains the difference in plain words, what to ask before you approve any quote, and when the manufacturer's cover is the better road. The examples below are typical scenarios, not records of real jobs.
Should you repair the board or replace it?
Short answer: It depends on how much of the board is damaged, and that is known only after testing. A clear, limited fault, such as a failed power part, may suit a component-level repair. Widespread damage, for example after a power surge or liquid, may make a whole board the sensible choice. Ask for the scope of work in writing before you say yes.
What do 'dead' and 'board' mean here?
The board (also called the motherboard) is the main circuit board that joins the processor, memory, storage and screen. In an All-in-One, it sits behind the display along with the power supply. 'Dead' can mean three different things. The power supply (the part that turns mains current into low voltage) may have failed. A small part on the board may have failed. Or large areas of the board may be damaged. Each has a different repair.
Do not open the back of an All-in-One at home. The panel is often glued or clipped tightly, and the display cable and the power parts inside can be damaged by a careless tool.
What is the manufacturer's route?
If the All-in-One is still in warranty, or you bought a Care Pack (an extended service plan sold with the device), use that first. Your invoice and serial number show what you hold. For an out-of-warranty machine, ask HP or check HP's support page for the options for your exact model.
What can an independent repair do for this fault?
Laptop Repair World, founded in 2007, has one store at MG Road, Secunderabad, and offers doorstep service across Hyderabad. For a doorstep visit, there is a ₹149 doorstep visit fee, waived when you approve laptop repair with us. No Fix No Fee covers the repair charge: if the fault is not fixed, there is no repair charge. The visit fee is waived only when you approve the repair.
We test the power supply, the power button circuit and the board to find where the fault lies. Our written quotation lists parts, labour, GST and the visit fee before any work starts. Each part is named as original, compatible or refurbished, with its own warranty. If testing finds another fault, you approve a revised quotation before further paid work. Condition, serial number and accessories are recorded when we collect a device. After the work, we show you the repaired function working, with a short written record, and follow up by call or message. Our repair warranty is 30 days, subject to its terms. Same-day completion is possible for eligible jobs, when the part is on hand and a technician is free.
How do the two scopes compare?
Ask each shop the same questions in the same order. The exact quote comes after diagnosis and is shared in writing for your approval. A quote that gives one total and no scope cannot be compared with another, so do not approve it yet.
What does a typical case look like?
An All-in-One goes off during a thunderstorm and will not switch on again. A technician checks the power supply first and finds it working. The board shows damage in one small area, so a component-level repair is quoted with the parts named. In another typical case, the board shows damage in many places after a surge, and the written quote says a replacement board is the more sensible scope. The same fault on the surface, a dead machine, led to two different decisions.
How do power cuts and storms affect an All-in-One in India?
Voltage spikes when power returns after a cut are a common cause of power faults in India, and monsoon humidity can add to the problem. Plug the All-in-One into a good surge-protected socket or a UPS (a small battery unit that smooths the supply), and unplug it during heavy storms. A cheap extension board with no surge protection gives little defence. Our guide on HP All-in-One repair lists other common faults, and the post on repairing or replacing an All-in-One covers the question of the whole machine.
When is the manufacturer's cover the better choice?
Choose the brand's route when the machine is within warranty, or when a Care Pack or accidental-damage plan is active. These are exactly the cases where cover exists to pay for the repair. Our page on HP manufacturer repair centre versus independent repair sets out the questions to ask. An independent repair makes sense when cover has ended and you want a written scope to compare.
When to get help
- The All-in-One shows no light, no fan sound and no response to the power button.
- It switched off after a power cut, a surge or a storm.
- It restarts by itself or clicks and then goes silent.
- You have a quote that says 'board' without saying what is wrong with it.

A note from the LRW Engineer Team
Before any work, copy down the serial number and take a photo of the back label. If you can, note what happened just before it stopped, such as a power cut or a smell. That short note helps a technician start in the right place, and it makes any quote easier to check.
