Laptop series HP Laptop 15 - one of the most popular budget and mid-budget devices on the market. Their disassembly may be required to clean dust, replace thermal paste, upgrade RAM or SSD, as well as repair the keyboard or cables. However, the design of these models has a number of features that are important to consider in order not to damage the case or internal components.
Unlike business lines HP EliteBook or ProBook, where disassembly is often simplified due to modular design, Laptop 15 series may turn out to be more capricious. There are hidden latches, non-obvious battery mounts, and even options with soldered memory. This article will help you avoid common mistakes and carry out disassembly as carefully as possible - be it a model 15-dw1xxx, 15-da0xxx or 15-dy2xxx.
Preparing for Disassembly: Tools and Precautions
Before you begin, make sure you have everything you need. Minimum set of tools for disassembly HP Laptop 15 includes:
- ✅ Plastic picks (2-3 pcs.) - for safe separation of the housing latches.
- ✅ Phillips screwdriver PH00 (magnetic) - most of the screws in these models are of this size.
- ✅ Tweezers - for removing small cables or screws.
- ✅ Antistatic wrist strap — protects components from static electricity.
- ✅ Thermal paste (if you are planning a replacement) - for example, Arctic MX-6 or Noctua NT-H2.
Also prepare your workplace: It is strictly forbidden to disassemble the laptop on a carpet or soft surface - this may lead to loss of screws or damage to the motherboard. It is optimal to use a table with a hard surface and place an antistatic mat or at least a sheet of paper under the laptop.
⚠️ Attention: If your HP Laptop 15 It is under warranty and disassembly will void it. In models with soldered RAM (for example, 15-dw1076ur) RAM upgrade is not possible - check your model specifications in advance.

Removing the back cover: hidden latches and screws
The first stage is dismantling the bottom panel. Most models HP Laptop 15 it is attached to 8–10 screws (depending on modification) and additional plastic latches. It is important to unscrew all screws, including those hidden under the rubber feet - they're easy to miss!
After removing the screws, carefully pry the cover open with a plastic pick, starting at the corner next to the screen hinges. Don't use force - if the lid does not budge, it means you missed a screw or the latch is not yet unlocked. In models 15-dy2xxx Often there is an additional mount near the power connector.
☑️ Check before removing the cover
| Model | Number of screws | Mounting features |
|---|---|---|
| HP Laptop 15-dw1xxx | 8–9 | Screw under the left leg, latches around the perimeter |
| HP Laptop 15-da0xxx | 10 | Additional screw near the cooler |
| HP Laptop 15-dy2xxx | 9 | Latch near the power connector |
Disabling the battery: why is it critical?
After removing the cover, the first thing you need to do is disconnect battery. B HP Laptop 15 it is usually secured with 2-3 screws and connected via a snap-on connector. Never touch the motherboard while the battery is connected - even when turned off, voltage may remain on the board, which will damage the components.
In some models (for example, 15-dw1056ur) the battery is glued to the body. In this case, you need to carefully pry it off with a plastic card, after heating it with a hairdryer (temperature no higher than 60°C) so as not to damage the lithium-polymer elements.
⚠️ Attention: If, after disconnecting the battery, the laptop does not turn on from the power supply, check the fuse on the motherboard (located next to the power connector). Its burnout is a common problem during careless disassembly.
Take photos of the location of the screws and cables before removing them - this will save time when reassembling.
Removing the cooling system and replacing thermal paste
Cooling system in HP Laptop 15 usually consists of a heatsink, heat pipes and a fan. To remove it, you need to:
- Unscrew 3-4 screws securing the cooler.
- Disconnect the fan connector from the motherboard.
- Carefully remove the heatsink, rocking it from side to side (the thermal paste may “stick”).
When replacing thermal paste, completely remove the old layer from the processor and video chip (if any) using isopropyl alcohol (90%+) and a lint-free wipe. The new layer should be thin - a pea of 4-5 mm in diameter is enough for the CPU. For GPU (if discrete graphics are present, for example, NVIDIA MX250) - a little more.
What happens if you overdo it with thermal paste?
A layer that is too thick impairs heat transfer, which leads to overheating. In the worst case scenario, thermal paste can leak onto the motherboard components and cause a short circuit.
Replacing RAM and SSD: nuances for different models
In the majority HP Laptop 15 RAM installed in one slot (often soldered) and the SSD has a form factor M.2 2242/2280. However there are exceptions:
- 🔹Models 15-dw1xxx (until 2020) - often have two RAM slots (one is busy, the other is free).
- 🔹Models 15-dy2xxx (2021–2023) - memory soldered in 90% of cases, upgrade is not possible.
- 🔹 SSD can be like
SATA, soNVMe— check the markings on the sticker of the old disk.
When installing a new SSD, make sure it is compatible with the connector: M.2 SATA And M.2 NVMe Look similar, but not interchangeable! To replace RAM, use modules that support DDR4-2666/3200 MHz (depending on processor generation).
Before purchasing RAM or SSD, check the supported specifications in the documentation for your model - for example, on the website HP Support by serial number.
Assembling a laptop: how to avoid mistakes
Reassembly is often more difficult than disassembly. Follow these rules:
- Make sure all loops (keyboard, touchpad, display) are connected tightly - they should click.
- Tighten the screws criss-crossto avoid distortion of the cover.
- Before final assembly, check the operation of the laptop without lid (connecting the power supply and monitor via HDMI).
If the laptop does not turn on after assembly, check:
- 🔌 Connecting the battery and power supply.
- 🖥️ Density of RAM and SSD.
- 🔧 All screws present - a missing screw can cause a short circuit.
FAQ: answers to frequently asked questions
Is it possible to disassemble HP Laptop 15 without special tools?
Theoretically, yes, but the risk of damaging the latches or the case is extremely high. Plastic picks are inexpensive (from 50 rubles), but they prevent chipping of the plastic, which will then be impossible to hide. If you don't have picks, use plastic card (for example, banking), but proceed with extreme caution.
How can I tell if the memory is soldered on my model?
There are two ways:
- View specifications on the website HP according to an exact model (for example, 15-dw1076ur).
- Remove the back cover and visually check - if there are no RAM slots, the memory is soldered.
On models with processors Intel 10th generation and newer memory is often soldered, in older ones (8th–9th generation) it is usually removable.
What should I do if the keyboard does not work after disassembling?
Most likely the problem is in the cable. Check:
- The tightness of the connection of the cable to the motherboard (must be secured with a latch).
- Integrity of the cable - if it is torn, a replacement will be required (cost ~500–1500 rubles).
- There is damage to the keyboard itself (for example, liquid ingress).
How often should you clean your laptop from dust?
The recommended frequency depends on the operating conditions:
- 🏠 Home use (clean room) - once every 1.5–2 years.
- 🌳 Dusty room or pets - once every 6-12 months.
- 🚬 Smokers indoors — cleaning every 6 months (resin settles on the fan blades).
Signs that cleaning is necessary: increased cooler noise, overheating (CPU temperature above 90°C under load), spontaneous shutdowns.
